132-515: These pigs are typically black, on rare occasions having white markings. They have long snouts that slowly converge downward, have erect, floppy ears, and short, shiny hair. Their face is similar to that of a wild boar ’s. They typically reach a weight of 400 to 600 pounds (180 to 270 kg), with males averaging 550 pounds (250 kg) and females 450 pounds (200 kg). The sows are known as good mothers, having litters that average 5 to 6 piglets. The Mulefoot likely originated with swine brought to

264-423: A Komodo dragon reputedly suffer from said sepsis and will later be eaten by the same or other lizards. Komodo dragons eat by tearing large chunks of flesh and swallowing them whole while holding the carcass down with their forelegs. For smaller prey up to the size of a goat, their loosely articulated jaws, flexible skulls, and expandable stomachs allow them to swallow prey whole. The undigested vegetable contents of

396-461: A W chromosome become WW and fail to develop, meaning that only males are produced by parthenogenesis in this species. It has been hypothesised that this reproductive adaptation allows a single female to enter an isolated ecological niche (such as an island) and by parthenogenesis produce male offspring, thereby establishing a sexually reproducing population (via reproduction with her offspring that can result in both male and female young). Despite

528-790: A case of intraguild predation , brought on by interspecific competition for human handouts. There is also at least one recorded case of a group of wild boar attacking, killing, and eating an adult, healthy female axis deer ( Axis axis ) as a pack. Stable isotope analysis of fossil wild boar tooth enamel from the late Middle Pleistocene found in Thailand indicate that it fed on a versatile mixed vegetation. Piglets are vulnerable to attack from medium-sized felids like Eurasian lynx ( Lynx lynx ), jungle cats ( Felis chaus ), and snow leopards ( Panthera uncia ), as well as other carnivorans like brown bears ( Ursus arctos ) and yellow-throated martens ( Martes flavigula ). The wolf ( Canis lupus )

660-645: A couple of months, dying in October and November 1926. The first Komodo dragons were displayed at London Zoo in 1927. A Komodo dragon was exhibited in 1934 in the United States at the National Zoo in Washington, D.C. , but it lived for only two years. More attempts to exhibit Komodo dragons were made, but the lifespan of the animals in captivity at the time proved very short, averaging five years in

792-486: A light-coloured patch running backward from the corners of the mouth. Coat colour also varies with age, with piglets having light brown or rusty-brown fur with pale bands extending from the flanks and back. The wild boar produces a number of different sounds which are divided into three categories: Its sense of smell is very well developed to the point that the animal is used for drug detection in Germany. Its hearing

924-690: A male dragon. After Flora's eggs' condition had been discovered, testing showed Sungai's eggs were also produced without outside fertilization. On 31 January 2008, the Sedgwick County Zoo in Wichita, Kansas , became the first zoo in the Americas to document parthenogenesis in Komodo dragons. The zoo has two adult female Komodo dragons, one of which laid about 17 eggs on 19–20 May 2007. Only two eggs were incubated and hatched due to space issues;

1056-606: A male, an adaptation known as superfecundation . On 20 December 2006, it was reported that Flora, a captive Komodo dragon living in the Chester Zoo in England, was the second known Komodo dragon to have laid unfertilised eggs: she laid 11 eggs, and seven of them hatched, all of them male. Scientists at Liverpool University in England performed genetic tests on three eggs that collapsed after being moved to an incubator, and verified Flora had never been in physical contact with

1188-403: A mane running down the back, which is particularly apparent during autumn and winter. The canine teeth are also much more prominent in males and grow throughout life. The upper canines are relatively short and grow sideways early in life, though they gradually curve upwards. The lower canines are much sharper and longer, with the exposed parts measuring 10–12 cm (3.9–4.7 in) in length. In

1320-1072: A mass of horns, hair, and teeth known as the gastric pellet, which is covered in malodorous mucus. After regurgitating the gastric pellet, it rubs its face in the dirt or on bushes to get rid of the mucus. The eating habits of Komodo dragons follow a hierarchy, with the larger animals generally eating before the smaller ones. The largest male typically asserts his dominance and the smaller males show their submission by use of body language and rumbling hisses. Dragons of equal size may resort to "wrestling". Losers usually retreat, though they have been known to be killed and eaten by victors. The Komodo dragon's diet varies depending on stage of growth. Young Komodo dragons will eat insects, birds and bird's eggs and small reptiles, while larger Komodo dragons (typically over 20 kg (44 lb)) prefer large ungulate prey, such as Javan rusa deer, wild pigs and water buffalo . Occasionally, they attack and bite humans. Sometimes they consume human corpses, digging up bodies from shallow graves. This habit of raiding graves caused

1452-622: A mix of both wild boar and domestic pigs. They are now known to be present in Dumfries and Galloway and a number of sites in the Highlands , mainly centred around the Loch Ness area. They can be killed there legally without a license and are culled by land managers as wild populations appear occasionally. As of 2024 , an agency that advises the Scottish government estimates that Scotland

1584-530: A poor source of leather. Additionally, these osteoderms become more extensive and variable in shape as the Komodo dragon ages, ossifying more extensively as the lizard grows. These osteoderms are absent in hatchlings and juveniles, indicating that the natural armor develops as a product of age and competition between adults for protection in intraspecific combat over food and mates. Komodo dragons have ziphodont teeth, which are defined as teeth that are laterally flattened, recurved, and with serrated tooth crowns where

1716-428: A prey animal's stomach and intestines are typically avoided. Copious amounts of red saliva the Komodo dragons produce help to lubricate the food, but swallowing is still a long process (15–20 minutes to swallow a goat). A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully that the tree is knocked down. A small tube under

1848-482: A short peptide dubbed DRGN-1 and tested it against multidrug-resistant (MDR) pathogens. Preliminary results of these tests show that DRGN-1 is effective in killing drug-resistant bacterial strains and even some fungi. It has the added observed benefit of significantly promoting wound healing in both uninfected and mixed biofilm infected wounds. In late 2005, researchers at the University of Melbourne speculated

1980-613: A skull from a recently killed individual in the Annamite Range , Laos, in 1995. Subsequent studies indicated that Sus bucculentus was not a valid taxon. As of 2022 the Mammal Diversity Database included it in Sus scrofa . The wild boar is a bulky, massively built suid with short and relatively thin legs. The trunk is short and robust, while the hindquarters are comparatively underdeveloped. The region behind

2112-523: A small tiger and a tigress to death in self-defense. A "large male tiger" died of wounds inflicted by an old wild boar it had killed in "a battle royal" between the two animals. In the Amur region , wild boars are one of the two most important prey species for Siberian tigers , alongside the Manchurian wapiti ( Cervus canadensis xanthopygus ), with the two species collectively comprising roughly 80% of

2244-582: A stealthy approach. When suitable prey arrives near a dragon's ambush site, it will suddenly charge at the animal at high speeds and go for the underside or the throat. Komodo dragons do not deliberately allow the prey to escape with fatal injuries but try to kill prey outright using a combination of lacerating damage and blood loss. They have been recorded as killing wild pigs within seconds, and observations of Komodo dragons tracking prey for long distances are likely misinterpreted cases of prey escaping an attack before succumbing to infection. Most prey attacked by

2376-552: A study reported no agitation in wild Komodo dragons in response to whispers, raised voices, or shouts. This was disputed when London Zoo employee Joan Procter trained a captive specimen to come out to feed at the sound of her voice, even when she could not be seen. The Komodo dragon can see objects as far away as 300 m (980 ft), but because its retinas only contain cones , it is thought to have poor night vision. It can distinguish colours, but has poor visual discrimination of stationary objects. As with many other reptiles,

2508-413: A support. As it matures, its claws are used primarily as weapons, as its great size makes climbing impractical. For shelter, the Komodo dragon digs holes that can measure from 1 to 3 m (3.3 to 9.8 ft) wide with its powerful forelimbs and claws. Because of its large size and habit of sleeping in these burrows, it is able to conserve body heat throughout the night and minimise its basking period

2640-557: A third domestication event with the Near Eastern genes dying out in European pig stock. Modern domesticated pigs have involved complex exchanges, with European domesticated lines being exported in turn to the ancient Near East. Historical records indicate that Asian pigs were introduced into Europe during the 18th and early 19th centuries. Domestic pigs tend to have much more developed hindquarters than their wild boar ancestors, to

2772-412: A very narrow view of oral secretions and resulted in misinterpretation of reptilian evolution." According to these scientists "reptilian oral secretions contribute to many biological roles other than to quickly dispatch prey." These researchers concluded that, "Calling all in this clade venomous implies an overall potential danger that does not exist, misleads in the assessment of medical risks, and confuses

2904-530: A year later. However, estrus usually first occurs after two years in sows, while males begin participating in the rut after 4–5 years, as they are not permitted to mate by the older males. The maximum lifespan in the wild is 10–14 years, though few specimens survive past 4–5 years. Boars in captivity have lived for 20 years. The wild boar inhabits a diverse array of habitats from boreal taigas to deserts . In mountainous regions, it can even occupy alpine zones, occurring up to 1,900 m (6,200 ft) in

3036-552: Is a highly versatile omnivore , whose diversity in choice of food is comparable to that of humans . Their foods can be divided into four categories: A 50 kg (110 lb) boar needs around 4,000–4,500 calories of food per day, though this required amount increases during winter and pregnancy, with the majority of its diet consisting of food items dug from the ground, like underground plant material and burrowing animals. Acorns and beechnuts are invariably its most important food items in temperate zones , as they are rich in

3168-424: Is also acute, though its eyesight is comparatively weak, lacking color vision and being unable to recognise a standing human 10–15 metres (33–49 ft) away. Pigs are one of four known mammalian taxa which possess mutations in the nicotinic acetylcholine receptor that protect against snake venom. Mongooses , honey badgers , hedgehogs , and pigs all have modifications to the receptor pocket which prevents

3300-671: Is an exhausting effort for the neonates, which break out of their eggshells with an egg tooth that falls off before long. After cutting themselves out, the hatchlings may lie in their eggshells for hours before starting to dig out of the nest. They are born quite defenseless and are vulnerable to predation. Sixteen youngsters from a single nest were on average 46.5 cm long and weighed 105.1 grams. Young Komodo dragons spend much of their first few years in trees, where they are relatively safe from predators, including cannibalistic adults, as juvenile dragons make up 10% of their diets. The habit of cannibalism may be advantageous in sustaining

3432-497: Is home to a few thousand wild boars. Locals around Loch Ness that were interviewed by The New York Times believed that the boars were becoming an increasingly worse problem, and farmers noted that they had killed and eaten several lambs. Wild boars are an invasive species in the Americas, having been introduced by European explorers and settlers in the 16th century to serve as a source of food. Wild boars now cause problems including out-competing native species for food, destroying

3564-488: Is illegal to import, breed, release, possess, sell, distribute, trade, transport, hunt, or trap Eurasian boars. Hunting and trapping is done systematically, to increase the chance of eradication and to remove the incentive to illegally release boars, which have mostly been spread deliberately by sport hunters. While domestic pigs, both captive and feral (popularly termed "razorbacks"), have been in North America since

3696-713: Is largely due in part to the local leopard subspecies' large size. Boars of all ages were once the primary prey of the tiger ( Panthera tigris ) in Transcaucasia, Kazakhstan, Middle Asia and the Far East up until the late 19th century. In modern times, tiger numbers are too low to have a limiting effect on boar populations. A single tiger can systematically destroy an entire sounder by preying on its members one by one, before moving on to another sounder. Tigers have been noted to chase boars for longer distances than with other prey. In two rare cases, boars were reported to gore

3828-439: Is most active in the day, although it exhibits some nocturnal activity. Komodo dragons are solitary, coming together only to breed and eat. They are capable of running rapidly in brief sprints up to 20 km/h (12 mph), diving up to 4.5 m (15 ft), and climbing trees proficiently when young through use of their strong claws. To catch out-of-reach prey, the Komodo dragon may stand on its hind legs and use its tail as

3960-614: Is prohibited. Despite this, there are occasional reports of illegal attempts to trade in live Komodo dragons. The most recent attempt was in March 2019, when Indonesian police in the East Java city of Surabaya reported that a criminal network had been caught trying to smuggle 41 young Komodo dragons out of Indonesia. The plan was said to include shipping the animals to several other countries in Southeast Asia through Singapore. It

4092-500: Is reinforced by armoured scales, which contain tiny bones called osteoderms that function as a sort of natural chain-mail . The only areas lacking osteoderms on the head of the adult Komodo dragon are around the eyes, nostrils, mouth margins, and parietal eye , a light-sensing organ on the top of the head. Where lizards typically have one or two varying patterns or shapes of osteoderms, komodos have four: rosette, platy, dendritic, and vermiform. This rugged hide makes Komodo dragon skin

4224-403: Is the main predator of wild boar throughout most of its range. A single wolf can kill around 50 to 80 boars of differing ages in one year. In Italy and Belarus' Belovezhskaya Pushcha National Park , boars are the wolf's primary prey, despite an abundance of alternative, less powerful ungulates. Wolves are particularly threatening during the winter, when deep snow impedes the boars' movements. In

4356-802: The Americas and Australia . As true wild boars became extinct in Great Britain before the development of Modern English , the same terms are often used for both true wild boar and pigs, especially large or semi-wild ones. The English boar stems from the Old English bār , which is thought to be derived from the West Germanic bair , of unknown origin. Boar is sometimes used specifically to refer to males, and may also be used to refer to male domesticated pigs, especially breeding males that have not been castrated. Sow ,

4488-766: The British Isles to Korea and the Sunda Islands . The northern limit of its range extended from southern Scandinavia to southern Siberia and Japan . Within this range, it was only absent in extremely dry deserts and alpine zones. It was once found in North Africa along the Nile valley up to Khartoum and north of the Sahara . The species occurs on a few Ionian and Aegean Islands , sometimes swimming between islands. The reconstructed northern boundary of

4620-717: The Carpathians , 2,600 m (8,500 ft) in the Caucasus and up to 3,600–4,000 m (11,800–13,100 ft) in the mountains in Central Asia and Kazakhstan . In order to survive in a given area, wild boars require a habitat fulfilling three conditions: heavily brushed areas providing shelter from predators, water for drinking and bathing purposes and an absence of regular snowfall. The main habitats favored by boars in Europe are deciduous and mixed forests , with

4752-696: The Dutch colonial administration. Widespread notoriety came after 1912, when Peter Ouwens , the director of the Zoological Museum of Bogor , Java , published a paper on the topic after receiving a photo and a skin from the lieutenant, as well as two other specimens from a collector. The first two live Komodo dragons to arrive in Europe were exhibited in the Reptile House at London Zoo when it opened in 1927. Joan Beauchamp Procter made some of

4884-537: The Far East and the Lesser Sunda Islands , where it is replaced by the tiger and Komodo dragon respectively. The wild boar has a long history of association with humans , having been the ancestor of most domestic pig breeds and a big-game animal for millennia. Boars have also re- hybridized in recent decades with feral pigs ; these boar–pig hybrids have become a serious pest wild animal in

5016-639: The Giza Zoo , with wild populations having disappeared by 1894–1902. Prince Kamal el Dine Hussein attempted to repopulate Wadi El Natrun with boars of Hungarian stock, but they were quickly exterminated by poachers. A revival of boar populations began in the middle of the 20th century. By 1950, wild boar had once again reached their original northern boundary in many parts of their Asiatic range. By 1960, they reached Leningrad and Moscow and by 1975, they were to be found in Archangelsk and Astrakhan . In

5148-715: The Gulf Coast by the Spanish; however, exactly when they originated as a syndactyl animal is not clear. While pigs with single hooves are found in writings as far back as Aristotle , the Mulefoot is the only population to be considered a breed , having an established standard type. The breed is possibly closely related to the Choctaw hog , and may share a similar ancestry. The Spanish-descended ungulates were minimally managed, with some selective breeding , which continued into

5280-764: The Himalayas . It is absent in the higher elevations of the Pamir and the Tian Shan , though they do occur in the Tarim Basin and on the lower slopes of the Tien Shan. In recent centuries, the range of wild boar has changed dramatically, largely due to hunting by humans and more recently because of captive wild boar escaping into the wild. Prior to the 20th century, boar populations had declined in numerous areas, with British populations probably becoming extinct during

5412-529: The Komodo monitor , is a large reptile of the monitor lizard family Varanidae that is endemic to the Indonesian islands of Komodo , Rinca , Flores , and Gili Motang . It is the largest extant species of lizard , with the males growing to a maximum length of 3 m (9.8 ft) and weighing up to 150 kg (330 lb). As a result of their size, Komodo dragons are apex predators , and dominate

5544-496: The Old World . As of 2005 , up to 16 subspecies are recognized, which are divided into four regional groupings based on skull height and lacrimal bone length. The species lives in matriarchal societies consisting of interrelated females and their young (both male and female). Fully grown males are usually solitary outside the breeding season . The wolf is the wild boar's main predator in most of its natural range except in

5676-476: The Volga Delta and near some lakes and rivers of Kazakhstan have been recorded to feed extensively on fish like carp and Caspian roach . Boars in the former area will also feed on cormorant and heron chicks, bivalved molluscs , trapped muskrats and mice. There is at least one record of a boar killing and eating a bonnet macaque in southern India's Bandipur National Park , though this may have been

5808-635: The carbohydrates necessary for the buildup of fat reserves needed to survive lean periods. In Western Europe, underground plant material favoured by boars includes bracken , willow herb , bulbs, meadow herb roots and bulbs and the bulbs of cultivated crops. Such food is favoured in early spring and summer, but may also be eaten in autumn and winter during beechnut and acorn crop failures. Should regular wild foods become scarce, boars will eat tree bark and fungi , as well as visit cultivated potato and artichoke fields. Boar soil disturbance and foraging have been shown to facilitate invasive plants. Boars of

5940-530: The crocodile monitor . Many other monitor species as well as Chinese crocodile lizards and beaded lizards only have 1-2 replacement teeth behind each tooth position. As with other varanids, Komodo dragons have only a single ear bone, the stapes , for transferring vibrations from the tympanic membrane to the cochlea . This arrangement means they are likely restricted to sounds in the 400 to 2,000 hertz range, compared to humans who hear between 20 and 20,000 hertz. They were formerly thought to be deaf when

6072-428: The ecosystems in which they live. Komodo dragons hunt and ambush prey including invertebrates , birds, and mammals . Komodo dragons' group behavior in hunting is exceptional in the reptile world. The diet of Komodo dragons mainly consists of Javan rusa ( Rusa timorensis ), though they also eat considerable amounts of carrion . Komodo dragons also occasionally attack humans. Mating begins between May and August, and

6204-435: The meiosis reduction-divisions in her ovaries failing. When a female Komodo dragon (with ZW sex chromosomes) reproduces in this manner, she provides her progeny with only one chromosome from each of her pairs of chromosomes, including only one of her two sex chromosomes. This single set of chromosomes is duplicated in the egg, which develops parthenogenetically. Eggs receiving a Z chromosome become ZZ (male); those receiving

6336-437: The perentie ( Varanus giganteus ), other species of monitors, and agamids may be somewhat venomous. The team believes the immediate effects of bites from these lizards were caused by mild envenomation. Bites on human digits by a lace monitor ( V. varius ), a Komodo dragon, and a spotted tree monitor ( V. timorensis ) all produced similar effects: rapid swelling, localised disruption of blood clotting, and shooting pain up to

6468-499: The snake venom α-neurotoxin from binding. These represent four separate, independent mutations. Boars are typically social animals, living in female-dominated sounders consisting of barren sows and mothers with young led by an old matriarch. Male boars leave their sounder at the age of 8–15 months, while females either remain with their mothers or establish new territories nearby. Subadult males may live in loosely knit groups, while adult and elderly males tend to be solitary outside

6600-683: The vittatus subspecies in Ujung Kulon National Park in Java differ from most other populations by their primarily frugivorous diet, which consists of 50 different fruit species, especially figs , thus making them important seed dispersers. The wild boar can consume numerous genera of poisonous plants without ill effect, including Aconitum , Anemone , Calla , Caltha , Ferula and Pteridium . Boars may occasionally prey on small vertebrates like newborn deer fawns, leporids and galliform chicks. Boars inhabiting

6732-570: The 13th century. In the warm period after the ice age, wild boar lived in the southern parts of Sweden and Norway and north of Lake Ladoga in Karelia . It was previously thought that the species did not live in Finland during prehistory because no prehistoric wild boar bones had been found within the borders of the country. It was not until 2013, when a wild boar bone was found in Askola , that

6864-589: The 1970s they again occurred in Denmark and Sweden, where captive animals escaped and now survive in the wild. In England, wild boar populations re-established themselves in the 1990s, after escaping from specialist farms that had imported European stock. By the 11th century, wild boars were apparently already becoming rare in Britain. A 1087 forestry law enacted by William the Conqueror punished through blinding

6996-611: The 1970s, but since the early 1990s significant populations have re-established themselves after escapes from farms, the number of which has increased as the demand for meat from the species has grown. A 1998 MAFF (now DEFRA ) study on wild boar living wild in Britain confirmed the presence of two populations of wild boar living in Britain; one in Kent / East Sussex and another in Dorset . Another DEFRA report, in February 2008, confirmed

7128-556: The Auffenberg expedition proved enormously influential in raising Komodo dragons in captivity. Research after that of the Auffenberg family has shed more light on the nature of the Komodo dragon, with biologists such as Claudio Ciofi continuing to study the creatures. The Komodo dragon is also sometimes known as the Komodo monitor or the Komodo Island monitor in scientific literature, although these names are uncommon. To

7260-512: The Baltic regions, heavy snowfall can allow wolves to eliminate boars from an area almost completely. Wolves primarily target piglets and subadults and only rarely attack adult sows. Adult males are usually avoided entirely. Dholes ( Cuon alpinus ) may also prey on boars, to the point of keeping their numbers down in northwestern Bhutan, despite there being many more cattle in the area. Leopards ( Panthera pardus ) are predators of wild boar in

7392-637: The Caucasus (particularly Transcaucasia), the Russian Far East, India, China and Iran. In most areas, boars constitute only a small part of the leopard's diet. However, in Iran's Sarigol National Park, boars are the second most frequently targeted prey species after mouflon ( Ovis gmelini ), though adult individuals are generally avoided, as they are above the leopard's preferred weight range of 10–40 kg (22–88 lb). This dependence on wild boar

7524-462: The Komodo dragon primarily relies on its tongue to detect, taste , and smell stimuli , with the vomeronasal sense using the Jacobson's organ , rather than using the nostrils. With the help of a favorable wind and its habit of swinging its head from side to side as it walks, a Komodo dragon may be able to detect carrion from 4–9.5 km (2.5–5.9 mi) away. It only has a few taste buds in

7656-455: The Komodo dragon. In the wild, adult Komodo dragons usually weigh around 70 kg (150 lb), although captive specimens often weigh more. According to Guinness World Records , an average adult male will weigh 79 to 91 kg (174 to 201 lb) and measure 2.59 m (8.5 ft), while an average female will weigh 68 to 73 kg (150 to 161 lb) and measure 2.29 m (7.5 ft). The largest verified specimen in captivity

Wild boar The wild boar ( Sus scrofa ), also known as the wild swine , common wild pig , Eurasian wild pig , or simply wild pig , is a suid native to much of Eurasia and North Africa , and has been introduced to the Americas and Oceania . The species is now one of

7920-1028: The National Zoological Park. Studies were done by Walter Auffenberg, which were documented in his book The Behavioral Ecology of the Komodo Monitor , eventually allowing for more successful management and breeding of the dragons in captivity. Surabaya Zoo in Indonesia has been breeding Komodo dragons since 1990 and had 134 dragons in 2022, the largest collection outside its natural habitat. As of May 2009, there were 35 North American, 13 European, one Singaporean, two African, and two Australian institutions which housed captive Komodo dragons. In 2016, four Komodo dragons were transferred from Bronx zoo to Madras Crocodile Bank Trust in India. A variety of behaviors have been observed from captive specimens. Most individuals become relatively tame within

8052-569: The U.K.'s woodlands were discussed with Ralph Harmer of the Forestry Commission on the BBC Radio 's Farming Today radio programme in 2011. The programme prompted activist writer George Monbiot to propose a thorough population study, followed by the introduction of permit-controlled culling . In Scotland, wild boar are professionally referred to as 'feral pigs' as the genetics of the established feral populations may come from

8184-781: The Wae Wuul and Wolo Tado Reserves were opened on Flores to aid Komodo dragon conservation. Komodo dragons generally avoid encounters with humans. Juveniles are very shy and will flee quickly into a hideout if a human comes closer than about 100 metres (330 ft). Older animals will also retreat from humans from a shorter distance away. If cornered, they may react aggressively by gaping their mouth, hissing, and swinging their tail. If they are disturbed further, they may attack and bite. Although there are anecdotes of unprovoked Komodo dragons attacking or preying on humans, most of these reports are either not reputable or have subsequently been interpreted as defensive bites. Only very few cases are truly

8316-420: The advantages of such an adaptation, zoos are cautioned that parthenogenesis may be detrimental to genetic diversity. Attacks on humans are rare, but Komodo dragons have been responsible for several human fatalities, both in the wild and in captivity. According to data from Komodo National Park spanning a 38-year period between 1974 and 2012, there were 24 reported attacks on humans, five of them fatal. Most of

8448-422: The age of the expecting mother. For first-time breeders, it lasts 114–130 days, while it lasts 133–140 days in older sows. Farrowing occurs between March and May, with litter sizes depending on the age and nutrition of the mother. The average litter consists of 4–6 piglets, with the maximum being 10–12. The piglets are whelped in a nest constructed from twigs, grasses and leaves. Should the mother die prematurely,

8580-431: The animal had consumed a large meal. The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced, serrated teeth that can measure up to 2.5 cm (1 in) in length. Its saliva is frequently blood-tinged because its teeth are almost completely covered by gingival tissue that is naturally lacerated during feeding. It also has a long, yellow, deeply forked tongue . Komodo dragon skin

8712-623: The animal's Asian range ran from Lake Ladoga (at 60°N) through the area of Novgorod and Moscow into the southern Urals , where it reached 52°N. From there, the boundary passed Ishim and farther east the Irtysh at 56°N. In the eastern Baraba steppe (near Novosibirsk ) the boundary turned steep south, encircled the Altai Mountains and went again eastward including the Tannu-Ola Mountains and Lake Baikal . From here,

8844-417: The back of its throat. Its scales, some of which are reinforced with bone, have sensory plaques connected to nerves to facilitate its sense of touch. The scales around the ears, lips, chin, and soles of the feet may have three or more sensory plaques. The Komodo dragon prefers hot and dry places and typically lives in dry, open grassland, savanna, and tropical forest at low elevations. As an ectotherm , it

8976-435: The bigger islands (Komodo and Rinca), but decreased on smaller islands, such as Nusa Kode and Gili Motang, likely due to diminishing prey availability. On Padar , a former population of Komodo dragons has recently become extirpated , of which the last individuals were seen in 1975. It is widely assumed that the Komodo dragon died out on Padar following a major decline of populations of large ungulate prey, for which poaching

9108-399: The biological assessment of squamate biochemical systems." Evolutionary biologist Schwenk says that even if the lizards have venom-like proteins in their mouths they may be using them for a different function, and he doubts venom is necessary to explain the effect of a Komodo dragon bite, arguing that shock and blood loss are the primary factors. Mating occurs between May and August, with

9240-405: The body, with the shortest being around the face and limbs and the longest running along the back. These back bristles form the aforementioned mane prominent in males and stand erect when the animal is agitated. Colour is highly variable; specimens around Lake Balkhash are very lightly coloured, and can even be white, while some boars from Belarus and Ussuriland can be black. Some subspecies sport

9372-566: The boundary went slightly north of the Amur River eastward to its lower reaches at the Sea of Okhotsk . On Sakhalin , there are only fossil reports of wild boar. The southern boundaries in Europe and Asia were almost invariably identical to the seashores of these continents. It is absent in the dry regions of Mongolia from 44 to 46°N southward, in China westward of Sichuan and in India north of

9504-413: The breed registry and expand breeding programs to additional farms. As of 2013, The Livestock Conservancy considers the Mulefoot to be critically endangered, a categorization given to breeds with a population of fewer than 2,000 and yearly registrations of fewer than 200. As of 2006, there were estimated to be fewer than 200 purebred Mulefoot hogs in existence. Maveric Ranch took over conservatorship of

9636-1106: The breeding period, males develop a coating of subcutaneous tissue , which may be 2–3 cm (0.79–1.18 in) thick, extending from the shoulder blades to the rump, thus protecting vital organs during fights. Males sport a roughly chicken egg–sized sac of unclear function near the opening of the penis that collects urine and emits a sharp odour. Adult size and weight is largely determined by environmental factors; boars living in arid areas with little productivity tend to attain smaller sizes than their counterparts inhabiting areas with abundant food and water. In most of Europe , males average 75–100 kg (165–220 lb) in weight, 75–80 cm (30–31 in) in shoulder height and 150 cm (59 in) in body length, whereas females average 60–80 kg (130–180 lb) in weight, 70 cm (28 in) in shoulder height and 140 cm (55 in) in body length. In Europe's Mediterranean regions , males may reach average weights as low as 50 kg (110 lb) and females 45 kg (99 lb), with shoulder heights of 63–65 cm (25–26 in). In

9768-426: The breeding season. The breeding period in most areas lasts from November to January, though most mating only lasts a month and a half. Prior to mating, the males develop their subcutaneous armour in preparation for confronting rivals. The testicles double in size and the glands secrete a foamy yellowish liquid. Once ready to reproduce, males travel long distances in search of a sounder of sows, eating little on

9900-531: The earliest days of European colonization , pure wild boars were not introduced into the New World until the 19th century. The suids were released into the wild by wealthy landowners as big game animals. The initial introductions took place in fenced enclosures, though several escapes occurred, with the escapees sometimes intermixing with already established feral pig populations. Komodo dragon The Komodo dragon ( Varanus komodoensis ), also known as

10032-489: The earliest observations of these animals in captivity and she demonstrated their behaviour at a scientific meeting of the Zoological Society of London in 1928. The Komodo dragon was the driving factor for an expedition to Komodo Island by W. Douglas Burden in 1926. After returning with 12 preserved specimens and two live ones, this expedition provided the inspiration for the 1933 movie King Kong . It

10164-543: The early phases of courtship. Therefore, the male must fully restrain the female during coitus to avoid being hurt. Other courtship displays include males rubbing their chins on the female, hard scratches to the back, and licking. Copulation occurs when the male inserts one of his hemipenes into the female's cloaca . Komodo dragons may be monogamous and form "pair bonds", a rare behavior for lizards. Female Komodos lay their eggs from August to September and may use several types of locality; in one study, 60% laid their eggs in

10296-498: The ears long and broad. The species has well developed canine teeth , which protrude from the mouths of adult males. The medial hooves are larger and more elongated than the lateral ones and are capable of quick movements. The animal can run at a maximum speed of 40 km/h (25 mph) and jump at a height of 140–150 cm (55–59 in). Sexual dimorphism is very pronounced in the species, with males being typically 5–10% larger and 20–30% heavier than females. Males also sport

10428-740: The eggs are laid in September; as many as 20 eggs are deposited at a time in an abandoned megapode nest or in a self-dug nesting hole. The eggs are incubated for seven to eight months, hatching in April, when insects are most plentiful. Young Komodo dragons are vulnerable and dwell in trees to avoid predators, such as cannibalistic adults, which young Komodo dragons also try to repel by rolling in feces. They take 8 to 9 years to mature and are estimated to live up to 30 years. Komodo dragons were first recorded by Western scientists in 1910. Their large size and fearsome reputation make them popular zoo exhibits. In

10560-445: The eggs laid in September. During this period, males fight over females and territory by grappling with one another upon their hind legs, with the loser eventually being pinned to the ground. These males may vomit or defecate when preparing for the fight. The winner of the fight will then flick his long tongue at the female to gain information about her receptivity. Females are antagonistic and resist with their claws and teeth during

10692-651: The elbow, with some symptoms lasting for several hours. In 2009, the same researchers published further evidence demonstrating Komodo dragons possess a venomous bite. MRI scans of a preserved skull showed the presence of two glands in the lower jaw. The researchers extracted one of these glands from the head of a terminally ill dragon in the Singapore Zoological Gardens , and found it secreted several different toxic proteins . The known functions of these proteins include inhibition of blood clotting, lowering of blood pressure, muscle paralysis, and

10824-768: The exception of domestic pigs in Timor and Papua New Guinea (which appear to be of Sulawesi warty pig stock), the wild boar is the ancestor of most pig breeds . Archaeological evidence suggests that pigs were domesticated from wild boar as early as 13,000–12,700 BCE in the Near East in the Tigris Basin, being managed in the wild in a way similar to the way they are managed by some modern New Guineans. Remains of pigs have been dated to earlier than 11,400 BCE in Cyprus . Those animals must have been introduced from

10956-624: The existence of these two sites as 'established breeding areas' and identified a third in Gloucestershire / Herefordshire ; in the Forest of Dean / Ross on Wye area. A 'new breeding population' was also identified in Devon . There is another significant population in Dumfries and Galloway . Populations estimates were as follows: Population estimates for the Forest of Dean are disputed as, at

11088-566: The felid's prey. In Sikhote Alin , a tiger can kill 30–34 boars a year. Studies of tigers in India indicate that boars are usually secondary in preference to various cervids and bovids , though when boars are targeted, healthy adults are caught more frequently than young and sick specimens. On the islands of Komodo , Rinca and Flores , the boar's main predator is the Komodo dragon ( Varanus komodoensis ). The species originally occurred in North Africa and much of Eurasia ; from

11220-536: The first hatched on 31 January 2008, while the second hatched on 1 February. Both hatchlings were males. Komodo dragons have the ZW chromosomal sex-determination system , as opposed to the mammalian XY system . Male progeny prove Flora's unfertilized eggs were haploid (n) and doubled their chromosomes later to become diploid (2n) (by being fertilized by a polar body , or by chromosome duplication without cell division ), rather than by her laying diploid eggs by one of

11352-825: The fruit-bearing season. This is in contrast to the Caucasian and Transcaucasian mountain areas, where boars will occupy such fruit-bearing forests year-round. In the mountainous areas of the Russian Far East , the species inhabits nutpine groves, hilly mixed forests where Mongolian oak and Korean pine are present, swampy mixed taiga and coastal oak forests. In Transbaikalia , boars are restricted to river valleys with nut pine and shrubs. Boars are regularly encountered in pistachio groves in winter in some areas of Tajikistan and Turkmenistan , while in spring they migrate to open deserts; boar have also colonized deserts in several areas they have been introduced to. On

11484-423: The induction of hypothermia, leading to shock and loss of consciousness in envenomated prey. As a result of the discovery, the previous theory that bacteria were responsible for the deaths of Komodo victims was disputed. Other scientists have stated that this allegation of venom glands "has had the effect of underestimating the variety of complex roles played by oral secretions in the biology of reptiles, produced

11616-470: The islands of Komodo and Rinca , the boar mostly inhabits savanna or open monsoon forests, avoiding heavily forested areas unless pursued by humans. Wild boar are known to be competent swimmers, capable of covering long distances. In 2013, one boar was reported to have completed the 11-kilometre (7 mi) swim from France to Alderney in the Channel Islands . Due to concerns about disease, it

11748-553: The large size of adults, as medium-sized prey on the islands is rare. When the young approach a kill, they roll around in faecal matter and rest in the intestines of eviscerated animals to deter these hungry adults. Komodo dragons take approximately 8 to 9 years to mature, and may live for up to 30 years. A Komodo dragon at London Zoo named Sungai laid a clutch of eggs in late 2005 after being separated from male company for more than two years. Scientists initially assumed she had been able to store sperm from her earlier encounter with

11880-515: The last herd of purebred Mulefoot hogs. He acquired swine from all known purebred breeders, and used selective breeding to maintain the breed standard. By 1976, the registries for the breed closed, and the herd books, pedigrees and other registration information were lost. In 1993, Mark Fields and the American Livestock Breeds Conservancy (later The Livestock Conservancy ) began working with Holiday to re-establish

12012-603: The late Miocene , the ancestors of Komodo dragons had hybridized with the common ancestor of Australian sand monitors (including V. spenceri , V. gouldii , V. rosenbergi and V. panoptes ). Fossils from across Queensland demonstrate that the Komodo dragon was once present in Australia, with fossils spanning from the Early Pliocene (~3.8 million years ago) to the Middle Pleistocene , with

12144-582: The late 1800s. Breed standards for the Mulefoot arose around 1900. The breed was seen mainly in the Corn Belt and Mississippi River Valley . The early 20th century saw the breed at the peak of its popularity, with over 200 purebred herds and two breed associations . At the same time, some Mulefoots were exported to Canada, but the population was not maintained. In the mid-20th century, the population began to decline, and by 1964, one breeder, R. M. Holiday of Louisiana, Missouri , established what would become

12276-568: The leaves to clean their mouth ... Unlike people have been led to believe, they do not have chunks of rotting flesh from their meals on their teeth, cultivating bacteria." They do have a slashing bite, which normally includes a dose of their neurotoxin venom and anticoagulant saliva. Komodo dragons do not wait for prey to die and track it at a distance, as vipers do; observations of them hunting deer, boar and in some cases buffalo reveal that they kill prey in less than half an hour. The observation of prey dying of sepsis would then be explained by

12408-421: The low-lying habitats and valleys that the Komodo dragon depends on, as Komodo dragons do not range into the higher-altitude regions of the islands they inhabit. Based on projections, climate change will lead to a decline in suitable habitat of 8.4%, 30.2%, or 71% by 2050 depending on the climate change scenario . Without effective conservation actions, populations on Flores are extirpated in all scenarios, while in

12540-466: The mainland, which suggests domestication in the adjacent mainland by then. There was also a separate domestication in China, which took place about 8,000 years ago. DNA evidence from sub-fossil remains of teeth and jawbones of Neolithic pigs shows that the first domestic pigs in Europe had been brought from the Near East. This stimulated the domestication of local European wild boars, resulting in

12672-515: The modern S. verrucosus throughout the Eurasian mainland, restricting it to insular Asia. Its closest wild relative is the bearded pig of Malacca and surrounding islands. As of 2005 , 16 subspecies are recognised, which are divided into four regional groupings: sahariensis (Heim de Balzac, 1937) nipponicus (Heude, 1899) mediterraneus (Ulmansky, 1911) reiseri (Bolkay, 1925) sardous (Ströbel, 1882) With

12804-592: The more extreme scenarios, only the populations on Komodo and Rinca persist in highly reduced numbers. Rapid climate change mitigation is crucial for conserving the species in the wild. Other scientists have disputed the conclusions about the effects of climate change on Komodo dragon populations. Under Appendix I of CITES (the Convention on International Trade in Endangered Species), commercial international trade of Komodo dragon skins or specimens

12936-1176: The more productive areas of Eastern Europe , males average 110–130 kg (240–290 lb) in weight, 95 cm (37 in) in shoulder height and 160 cm (63 in) in body length, while females weigh 95 kg (209 lb), reach 85–90 cm (33–35 in) in shoulder height, and reach 145 cm (57 in) in body length. In Western and Central Europe , the largest males weigh 200 kg (440 lb) and females 120 kg (260 lb). In Northeastern Asia, large males can reach brown bear -like sizes, weighing 270 kg (600 lb) and measuring 110–118 cm (43–46 in) in shoulder height. Some adult males in Ussuriland and Manchuria have been recorded to weigh 300–350 kg (660–770 lb) and measure 125 cm (49 in) in shoulder height. Adults of this size are generally immune from wolf predation. Such giants are rare in modern times, as past overhunting has prevented animals from attaining their full growth. The winter coat consists of long, coarse bristles underlaid with short brown downy fur. The length of these bristles varies along

13068-484: The morning after. The Komodo dragon stays in the shade during the hottest part of the day and hunts in the afternoon. These special resting places, usually located on ridges with cool sea breezes, are marked with droppings and are cleared of vegetation. They serve as strategic locations from which to ambush deer. Komodo dragons are apex predators . They are carnivores; although they have been considered as eating mostly carrion, they will frequently ambush live prey with

13200-466: The most favorable areas consisting of forest composed of oak and beech enclosing marshes and meadows . In the Białowieża Forest , the animal's primary habitat consists of well-developed broad-leaved and mixed forests, along with marshy mixed forests, with coniferous forests and undergrowths being of secondary importance. Forests made up entirely of oak groves and beeches are used only during

13332-421: The mother be absent, the piglets lie closely pressed to each other. By two weeks of age, the piglets begin accompanying their mother on her journeys. Should danger be detected, the piglets take cover or stand immobile, relying on their camouflage to keep them hidden. The neonatal coat fades after three months, with adult colouration being attained at eight months. Although the lactation period lasts 2.5–3.5 months,

13464-525: The natives of Komodo Island , it is referred to as ora , buaya darat ('land crocodile'), or biawak raksasa ('giant monitor'). Genetic analysis of mitochondrial DNA shows the Komodo dragon to be the closest relative ( sister taxon ) of the Australian lace monitor ( V. varius ), with their common ancestor diverging from a lineage that gave rise to the crocodile monitor ( Varanus salvadorii ) of New Guinea . A 2021 study showed that during

13596-485: The natural instinct of water buffalos , who are not native to the islands where the Komodo dragon lives, to run into water after escaping an attack. The warm, faeces-filled water would then cause the infections. The study used samples from 16 captive dragons (10 adults and six neonates) from three US zoos. Researchers have isolated a powerful antibacterial peptide from the blood plasma of Komodo dragons, VK25. Based on their analysis of this peptide, they have synthesized

13728-423: The nests of orange-footed scrubfowl (a moundbuilder or megapode ), 20% on ground level and 20% in hilly areas. The females make many camouflage nests/holes to prevent other dragons from eating the eggs. Nests typically house one female, however a study found evidence of two females occasionally occupying the same den. Clutches contain an average of 20 eggs, which have an incubation period of 7–8 months. Hatching

13860-400: The nests of ground-nesting species, killing fawns and young domestic livestock, destroying agricultural crops, eating tree seeds and seedlings, destroying native vegetation and wetlands through wallowing, damaging water quality, coming into violent conflict with humans and pets and carrying pig and human diseases including brucellosis , trichinosis and pseudorabies . In some jurisdictions, it

13992-534: The occurrence of World War II, not resuming until the 1950s and 1960s, when studies examined the Komodo dragon's feeding behavior, reproduction, and body temperature. At around this time, an expedition was planned in which a long-term study of the Komodo dragon would be undertaken. This task was given to the Auffenberg family, who stayed on Komodo Island for 11 months in 1969. During their stay, Walter Auffenberg and his assistant Putra Sastrawan captured and tagged more than 50 Komodo dragons. Research from

14124-415: The piglets are adopted by the other sows in the sounder. Newborn piglets weigh around 600–1,000 grams, lacking underfur and bearing a single milk incisor and canine on each half of the jaw. There is intense competition between the piglets over the most milk-rich nipples, as the best-fed young grow faster and have stronger constitutions. The piglets do not leave the lair for their first week of life. Should

14256-413: The piglets begin displaying adult feeding behaviours at the age of 2–3 weeks. The permanent dentition is fully formed by 1–2 years. With the exception of the canines in males, the teeth stop growing during the middle of the fourth year. The canines in old males continue to grow throughout their lives, curving strongly as they age. Sows attain sexual maturity at the age of one year, with males attaining it

14388-524: The point where 70% of their body weight is concentrated in the posterior, which is the opposite of wild boar, where most of the muscles are concentrated on the head and shoulders. The Heude's pig ( Sus bucculentus ), also known as the Indochinese warty pig or Vietnam warty pig, was an alleged pig species found in Laos and Vietnam . It was virtually unknown and was feared extinct , until the discovery of

14520-424: The result of unprovoked attacks by atypical individuals who lost their fear of humans. Volcanic activity, earthquakes, loss of habitat, fire, tourism, loss of prey due to poaching , and illegal poaching of the dragons themselves have all contributed to the vulnerable status of the Komodo dragon. A major future threat to the species is climate change via both aridification and sea level rise , which can affect

14652-564: The serrations have a dentine core and a very thin enamel outer layer. This is the same type of dentition observed in many extinct theropod dinosaurs. The teeth of the insectivorous juveniles in contrast are barely recurved, with fewer and less well-developed serrations that lack dentine cores. A 2024 study published in Nature Ecology & Evolution found that Komodo dragons have orange, iron -enriched coatings on their tooth serrations and tips, as an adaptation for maintaining

14784-413: The sharp cutting edges. This feature is also observed to a lesser degree in a few other Australasian to Asian monitor species, though notably absent in a few other species from that range. Teeth are quickly replaced every 40 days, while maintaining up to 5 replacement teeth for each tooth position at any given time. This high rate of replacement and large number of replacement teeth is similar to that of

14916-539: The shoulder blades rises into a hump and the neck is short and thick to the point of being nearly immobile. The animal's head is very large, taking up to one-third of the body's entire length. The structure of the head is well suited for digging. The head acts as a plough, while the powerful neck muscles allow the animal to upturn considerable amounts of soil: it is capable of digging 8–10 cm (3.1–3.9 in) into frozen ground and can upturn rocks weighing 40–50 kg (88–110 lb). The eyes are small and deep-set and

15048-607: The species was found to have lived in Finland more than 8,000 years ago. It is believed, however, that man prevented its establishment by hunting. In Denmark , the last boar was shot at the beginning of the 19th century, and by 1900 they were absent in Tunisia and Sudan and large areas of Germany, Austria and Italy. In Russia, they were extirpated in wide areas by the 1930s. The last boar in Egypt reportedly died on 20 December 1912 in

15180-577: The time that the DEFRA population estimate was 100, a photo of a boar sounder in the forest near Staunton with over 33 animals visible was published and at about the same time over 30 boar were seen in a field near the original escape location of Weston under Penyard many kilometres or miles away. In early 2010 the Forestry Commission embarked on a cull, with the aim of reducing the boar population from an estimated 150 animals to 100. By August it

15312-427: The tongue that connects to the lungs allows it to breathe while swallowing. After eating up to 80% of its body weight in one meal, it drags itself to a sunny location to speed digestion, as the food could rot and poison the dragon if left undigested in its stomach for too long. Because of their slow metabolism, large dragons can survive on as few as 12 meals a year. After digestion, the Komodo dragon regurgitates

15444-589: The traditional name for a female, again comes from Old English and Germanic; it stems from Proto-Indo-European , and is related to the Latin : sus and Greek hus , and more closely to the New High German Sau . The young may be called piglets or boarlets . The animals' specific name scrofa is Latin for 'sow'. In hunting terminology, boars are given different designations according to their age: MtDNA studies indicate that

15576-565: The unlawful killing of a boar. Charles I attempted to reintroduce the species into the New Forest , but this population was exterminated in the 17th century during the English Civil War . Between their medieval extinction and the 1980s, when wild boar farming began, only a handful of captive wild boar, imported from the continent, were present in Britain. Occasional escapes of wild boar from wildlife parks have occurred as early as

15708-574: The victims were local villagers living around the national park. The Komodo dragon is classified by the IUCN as Endangered and is listed on the IUCN Red List . The species' sensitivity to natural and human-made threats has long been recognized by conservationists, zoological societies, and the Indonesian government. Komodo National Park was founded in 1980 to protect Komodo dragon populations on islands including Komodo, Rinca, and Padar. Later,

15840-704: The villagers of Komodo to move their graves from sandy to clay ground, and pile rocks on top of them, to deter the lizards. Dwarf species of Stegodon (a proboscidean related to living elephants) are suggested to have been a primary prey item of the Komodo dragon during the Pleistocene , prior to the introduction of their modern ungulate prey, which were only introduced to the islands in the Holocene , around 10-7,000 years ago. The Komodo dragon drinks by sucking water into its mouth via buccal pumping (a process also used for respiration), lifting its head, and letting

15972-476: The water run down its throat. Although previous studies proposed that Komodo dragon saliva contains a variety of highly septic bacteria that would help to bring down prey, research in 2013 suggested that the bacteria in the mouths of Komodo dragons are ordinary and similar to those found in other carnivores. Komodo dragons have good mouth hygiene. To quote Bryan Fry: "After they are done feeding, they will spend 10 to 15 minutes lip-licking and rubbing their head in

16104-403: The way. Once a sounder has been located, the male drives off all young animals and persistently chases the sows. At this point, the male fiercely fights potential rivals. A single male can mate with 5–10 sows. By the end of the rut, males are often badly mauled and have lost 20% of their body weight, with bite-induced injuries to the penis being common. The gestation period varies according to

16236-572: The widest-ranging mammals in the world, as well as the most widespread suiform . It has been assessed as least concern on the IUCN Red List due to its wide range, high numbers, and adaptability to a diversity of habitats. It has become an invasive species in part of its introduced range. Wild boars probably originated in Southeast Asia during the Early Pleistocene and outcompeted other suid species as they spread throughout

16368-477: The wild boar originated from islands in Southeast Asia such as Indonesia and the Philippines , and subsequently spread onto mainland Eurasia and North Africa. The earliest fossil finds of the species come from both Europe and Asia, and date back to the Early Pleistocene . By the late Villafranchian , S. scrofa largely displaced the related S. strozzii , a large, possibly swamp-adapted suid ancestral to

16500-453: The wild, their range has been reduced by human encroachment and is likely to contract further from the effects of climate change ; hence, they are listed as Endangered by the IUCN Red List . They are protected under Indonesian law , and Komodo National Park was founded in 1980 to aid protection efforts. Komodo dragons were first documented by Europeans in 1910, when rumors of a "land crocodile" reached Lieutenant van Steyn van Hensbroek of

16632-450: The youngest confirmed records of the species in Australia dating to at latest 330,000 years ago. In Australia, it coexisted with the even larger monitor species Varanus priscus also known as megalania, the largest terrestrial lizard ever. The oldest records of the Komodo dragon on Flores date to around 1.4 million years ago, during the Early Pleistocene . Additionally, Pleistocene fossils of Varanus found in Java and Timor may belong to

16764-470: Was 3.13 m (10 ft 3 in) long and weighed 166 kg (366 lb), including its undigested food. The largest wild specimen had a length 3.04 m (10 ft), a snout-vent length (SVL) 1.54 m (5 ft 1 in) and a mass of 81.5 kg (180 lb) excluding stomach contents. The heaviest reached a mass of 87.4 kg (193 lb). The study noted that weights greater than 100 kg (220 lb) were possible but only after

16896-470: Was also Burden who coined the common name "Komodo dragon". Three of his specimens were stuffed and are still on display in the American Museum of Natural History . The Dutch island administration, realizing the limited number of individuals in the wild, soon outlawed sport hunting and heavily limited the number of individuals taken for scientific study. Collecting expeditions ground to a halt with

17028-424: Was hoped that the animals could be sold for up to 500 million rupiah (around US$ 35,000) each. It was believed that the Komodo dragons had been smuggled out of East Nusa Tenggara province through the port at Ende in central Flores. In 2013, the total population of Komodo dragons in the wild was assessed as 3,222 individuals, declining to 3,092 in 2014 and 3,014 in 2015. Populations remained relatively stable on

17160-540: Was most likely responsible. Komodo dragons have long been sought-after zoo attractions, where their size and reputation make them popular exhibits. They are, however, rare in zoos because they are susceptible to infection and parasitic disease if captured from the wild, and do not readily reproduce in captivity. A pair of Komodo dragons was displayed at the Bronx Zoo in New York in September 1926, but they only lasted

17292-450: Was shot and incinerated. Wild boar rest in shelters, which contain insulating material like spruce branches and dry hay . These resting places are occupied by whole families (though males lie separately) and are often located in the vicinity of streams, in swamp forests and in tall grass or shrub thickets. Boars never defecate in their shelters and will cover themselves with soil and pine needles when irritated by insects. The wild boar

17424-594: Was stated that efforts were being made to reduce the population from 200 to 90, but that only 25 had been killed. The failure to meet cull targets was confirmed in February 2011. Wild boars have crossed the River Wye into Monmouthshire , Wales. Iolo Williams, the BBC Wales wildlife expert, attempted to film Welsh boar in late 2012. Many other sightings, across the UK, have also been reported. The effects of wild boar on
