44-550: Lisowski , Lisowsky , Lisovsky or Lisovski is a surname with variants in multiple languages. It is derived from the Polish noun lisъ (" fox "). In Poland, the surname is particularly common in southern regions. Fox All other species in Canini Foxes are small-to-medium-sized omnivorous mammals belonging to several genera of the family Canidae . They have a flattened skull; upright, triangular ears;
88-493: A fox. Fennec fox The fennec fox ( Vulpes zerda ) is a small crepuscular fox native to the deserts of North Africa, ranging from Western Sahara and Mauritania to the Sinai Peninsula . Its most distinctive feature is its unusually large ears, which serve to dissipate heat and listen for underground prey. The fennec is the smallest fox species. Its coat, ears, and kidney functions have adapted to
132-552: A pointed, slightly upturned snout ; and a long, bushy tail ("brush"). Twelve species belong to the monophyletic "true fox" group of genus Vulpes . Another 25 current or extinct species are sometimes called foxes – they are part of the paraphyletic group of the South American foxes or an outlying group, which consists of the bat-eared fox , gray fox , and island fox . Foxes live on every continent except Antarctica. The most common and widespread species of fox
176-460: A single chamber. Captive individuals reside in family groups consisting of several members. Fennec foxes exhibit playful behavior, especially among younger individuals. The fennec fox is omnivorous, feeding on small rodents , lizards ( geckos and skinks ), small birds and their eggs, insects, fruits, leaves , roots and also some tubers . It relies on the moisture content of prey, but drinks water when available. It hunts alone and digs in
220-426: A white marking . A fox's coat color and texture may vary due to the change in seasons; fox pelts are richer and denser in the colder months and lighter in the warmer months. To get rid of the dense winter coat, foxes moult once a year around April; the process begins from the feet, up the legs, and then along the back. Coat color may also change as the individual ages. A fox's dentition , like all other canids,
264-458: A woman in Clapham, London was bitten on the arm by a fox after she had left the door to her flat open. The fox appears in many cultures, usually in folklore . There are slight variations in their depictions. In European, Persian, East Asian, and Native American folklore, foxes are symbols of cunning and trickery —a reputation derived especially from their reputed ability to evade hunters. This
308-416: Is I 3/3, C 1/1, PM 4/4, M 3/2 = 42. (Bat-eared foxes have six extra molars, totalling in 48 teeth.) Foxes have pronounced carnassial pairs, which is characteristic of a carnivore . These pairs consist of the upper premolar and the lower first molar, and work together to shear tough material like flesh. Foxes' canines are pronounced, also characteristic of a carnivore, and are excellent in gripping prey. In
352-454: Is distributed throughout the Sahara, from Morocco and Mauritania to northern Sudan , through Egypt and its Sinai Peninsula . It inhabits small sand dunes and vast treeless sand areas with sparse vegetation such as grasses, sedges and small shrubs. Fennec foxes are primarily nocturnal, displaying heightened activity during the cooler nighttime hours. This behaviour helps them escape
396-615: Is limited to the forests that extend from the southernmost to the northwesternmost part of the island. Though the Nahuelbuta National Park is protected, 90% of the species live on Chiloé Island. A major issue the species faces is their dwindling, limited habitat due to the cutting and burning of the unprotected forests. Because of deforestation, the Darwin's fox habitat is shrinking, allowing for their competitor's ( chilla fox ) preferred habitat of open space, to increase;
440-548: Is often pressure to exclude them from these environments. The San Joaquin kit fox is a highly endangered species that has, ironically, become adapted to urban living in the San Joaquin Valley and Salinas Valley of southern California. Its diet includes mice, ground squirrels, rabbits, hares, bird eggs, and insects, and it has claimed habitats in open areas, golf courses, drainage basins, and school grounds. Though rare, bites by foxes have been reported; in 2018,
484-692: Is the Russian silver fox , which resulted in visible and behavioral changes, and is a case study of an animal population modeling according to human domestication needs. The current group of domesticated silver foxes are the result of nearly fifty years of experiments in the Soviet Union and Russia to de novo domesticate the silver morph of the red fox. This selective breeding resulted in physical and behavioral traits appearing that are frequently seen in domestic cats, dogs, and other animals, such as pigmentation changes, floppy ears, and curly tails. Notably,
SECTION 10
#1732783193502528-555: Is the red fox ( Vulpes vulpes ) with about 47 recognized subspecies . The global distribution of foxes, together with their widespread reputation for cunning, has contributed to their prominence in popular culture and folklore in many societies around the world. The hunting of foxes with packs of hounds, long an established pursuit in Europe, especially in the British Isles , was exported by European settlers to various parts of
572-510: Is the smallest canid species. Females range in head-to-body size from 34.5 to 39.5 cm (13.6 to 15.6 in) with a 23–25 cm (9.1–9.8 in) long tail and 9–9.5 cm (3.5–3.7 in) long ears, and weigh 1–1.9 kg (2.2–4.2 lb). Males are slightly larger, ranging in head-to-body size from 39 to 39.5 cm (15.4 to 15.6 in) with a 23–25 cm (9.1–9.8 in) long tail and 10 cm (3.9 in) long ears, weighing at least 1.3 kg (2.9 lb). The fennec fox
616-414: Is usually represented as a character possessing these traits. These traits are used on a wide variety of characters, either making them a nuisance to the story, a misunderstood hero, or a devious villain. In East Asian folklore, foxes are depicted as familiar spirits possessing magic powers. Similar to in the folklore of other regions, foxes are portrayed as mischievous, usually tricking other people, with
660-508: The IUCN have since downgraded the conservation status from crictically endangered in their 2004 and 2008 assessments to endangered in the 2016 assessment, following findings of a wider distribution than previously reported. On the Chilean mainland, the population is limited to Nahuelbuta National Park and the surrounding Valdivian rainforest . Similarly on Chiloé Island , their population
704-565: The Middle English southern dialectal "v" pronunciation instead of "f"; i.e., northern English "fox" versus southern English "vox". A group of foxes is referred to as a skulk , leash , or earth . Within the Canidae, the results of DNA analysis shows several phylogenetic divisions: Foxes are generally smaller than some other members of the family Canidae such as wolves and jackals , while they may be larger than some within
748-504: The New World . The word fox comes from Old English and derives from Proto-Germanic * fuhsaz . This in turn derives from Proto-Indo-European * puḱ- "thick-haired, tail." Male foxes are known as dogs , tods , or reynards ; females as vixens ; and young as cubs , pups , or kits , though the last term is not to be confused with the kit fox , a distinct species. "Vixen" is one of very few modern English words that retain
792-426: The copulation tie lasts up to two hours and 45 minutes. Gestation usually lasts between 50 and 52 days, though sometimes up to 63 days. After mating, the male becomes very aggressive and protects the female, and provides her with food during pregnancy and lactation . Females give birth between March and June to a litter of one to four pups that open their eyes after 8 to 11 days. Both female and male care for
836-516: The crab-eating fox ) have more specialized diets. Most species of fox consume around 1 kg (2.2 lb) of food every day. Foxes cache excess food, burying it for later consumption, usually under leaves, snow, or soil. While hunting, foxes tend to use a particular pouncing technique, such that they crouch down to camouflage themselves in the terrain and then use their hind legs to leap up with great force and land on top of their chosen prey. Using their pronounced canine teeth, they can then grip
880-500: The desert environment with high temperatures and little water. It mainly eats insects , small mammals and birds . The fennec has a life span of up to 14 years in captivity and about 10 years in the wild. Its main predators are the Verreaux's eagle-owl , jackals and other large mammals. Fennec families dig out burrows in the sand for habitation and protection, which can be as large as 120 m (1,300 sq ft) and adjoin
924-599: The California Channel Islands, it was found that the population of the island fox was so low due to an outbreak of canine distemper virus from 1999 to 2000 as well as predation by non-native golden eagles . Since 1993, the eagles have caused the population to decline by as much as 95%. Because of the low number of foxes, the population went through an Allee effect (an effect in which, at low enough densities, an individual's fitness decreases). Conservationists had to take healthy breeding pairs out of
SECTION 20
#1732783193502968-515: The Darwin's fox, subsequently, is being outcompeted. Another problem they face is their inability to fight off diseases transmitted by the increasing number of pet dogs. To conserve these animals, researchers suggest the need for the forests that link the Nahuelbuta National Park to the coast of Chile and in turn Chiloé Island and its forests, to be protected. They also suggest that other forests around Chile be examined to determine whether Darwin's foxes have previously existed there or can live there in
1012-460: The ability to disguise as an attractive female human . Others depict them as mystical, sacred creatures who can bring wonder or ruin. Nine-tailed foxes appear in Chinese folklore, literature, and mythology, in which, depending on the tale, they can be a good or a bad omen. The motif was eventually introduced from Chinese to Japanese and Korean cultures. The constellation Vulpecula represents
1056-410: The burrows of other families. Precise population figures are not known but are estimated from the frequency of sightings; these indicate that the fennec is currently not threatened by extinction. Knowledge of social interactions is limited to information gathered from captive animals. The fennec's fur is prized by the indigenous peoples of North Africa, and it is considered an exotic pet in some parts of
1100-645: The causes. African horned owl species such as the Pharaoh eagle-owl prey on fennec fox pups. Anecdotal reports exist about caracals , jackals , and striped hyenas also preying on the fennec fox. But according to nomads, the fennec fox is fast and changes directions so well that even their Salukis are hardly ever able to capture it. In North Africa, the fennec fox is commonly trapped for exhibition or sale to tourists. Expansion of permanent human settlements in southern Morocco caused its disappearance in these areas and restricted it to marginal areas. As of 2015,
1144-483: The early 19th century for sport, and have since become widespread through much of the country. They have caused population decline among many native species and prey on livestock, especially new lambs. Fox hunting is practiced as recreation in several other countries including Canada, France, Ireland, Italy, Russia, United States and Australia. There are many records of domesticated red foxes and others, but rarely of sustained domestication. A recent and notable exception
1188-478: The ears are whitish, but darker on the back. The ear to body ratio is the greatest in the canid family and likely helps in dissipating heat and locating vertebrates . It has dark streaks running from the inner eye to either side of the slender muzzle. Its large eyes are dark. The dental formula is 3.1.4.2 3.1.4.3 × 2 = 42 with small and narrow canines . The pads of its paws are covered with dense fur, which facilitates walking on hot, sandy soil. The fennec fox
1232-460: The extreme Saharan heat and reduces water loss through panting. A fennec fox digs its den in sand, either in open areas or places sheltered by plants with stable sand dunes . In compacted soils, dens are up to 120 m (1,300 sq ft) large, with up to 15 different entrances. In some cases, different families interconnect their dens, or locate them close together. In soft, looser sand, dens tend to be simpler with only one entrance leading to
1276-710: The family Canidae, foxes have partially retractable claws . Fox vibrissae, or whiskers , are black. The whiskers on the muzzle, known as mystacial vibrissae, average 100–110 millimetres ( 3 + 7 ⁄ 8 – 4 + 3 ⁄ 8 inches) long, while the whiskers everywhere else on the head average to be shorter in length. Whiskers (carpal vibrissae) are also on the forelimbs and average 40 mm ( 1 + 5 ⁄ 8 in) long, pointing downward and backward. Other physical characteristics vary according to habitat and adaptive significance. Fox species differ in fur color, length, and density. Coat colors range from pearly white to black-and-white to black flecked with white or grey on
1320-461: The family, such as raccoon dogs . In the largest species, the red fox , males weigh between 4.1 and 8.7 kg (9.0 and 19.2 lb), while the smallest species, the fennec fox , weighs just 0.7 to 1.6 kg ( 1 + 1 ⁄ 2 to 3 + 1 ⁄ 2 lb). Fox features typically include a triangular face, pointed ears, an elongated rostrum , and a bushy tail. They are digitigrade (meaning they walk on their toes). Unlike most members of
1364-632: The fennec fox is classified as Least concern on the IUCN Red List . It is listed in CITES Appendix II and is protected in Morocco and Western Sahara, Algeria, Tunisia and Egypt, where it has been documented in several protected areas. The fennec fox is bred commercially as an exotic pet . Commercial breeders remove the pups from their mother to hand-raise them, as tame foxes are more valuable. A breeders' registry has been set up in

1408-526: The first nonlinear oscillation studied and led to the derivation of the Lotka–Volterra equation . Fox meat is edible, though it is not considered a common cuisine in any country. Fox hunting originated in the United Kingdom in the 16th century. Hunting with dogs is now banned in the United Kingdom, though hunting without dogs is still permitted. Red foxes were introduced into Australia in
1452-565: The fruit intact. The island fox , though considered a near-threatened species throughout the world, is becoming increasingly endangered in its endemic environment of the California Channel Islands . A population on an island is smaller than those on the mainland because of limited resources like space, food and shelter. Island populations are therefore highly susceptible to external threats ranging from introduced predatory species and humans to extreme weather . On
1496-1143: The future, should the need to reintroduce the species to those areas arise. And finally, the researchers advise for the creation of a captive breeding program, in Chile, because of the limited number of mature individuals in the wild. Foxes are often considered pests or nuisance creatures for their opportunistic attacks on poultry and other small livestock. Fox attacks on humans are not common. Many foxes adapt well to human environments, with several species classified as "resident urban carnivores" for their ability to sustain populations entirely within urban boundaries. Foxes in urban areas can live longer and can have smaller litter sizes than foxes in non-urban areas. Urban foxes are ubiquitous in Europe, where they show altered behaviors compared to non-urban foxes, including increased population density, smaller territory, and pack foraging. Foxes have been introduced in numerous locations, with varying effects on indigenous flora and fauna. In some countries, foxes are major predators of rabbits and hens. Population oscillations of these two species were
1540-800: The mammary gland to the nipple, allowing for milk to be carried to the nipple. The fox's vocal repertoire is vast, and includes: In the case of domesticated foxes, the whining seems to remain in adult individuals as a sign of excitement and submission in the presence of their owners. Canids commonly known as foxes include the following genera and species: Several fox species are endangered in their native environments. Pressures placed on foxes include habitat loss and being hunted for pelts, other trade, or control. Due in part to their opportunistic hunting style and industriousness, foxes are commonly resented as nuisance animals. Contrastingly, foxes, while often considered pests themselves, have been successfully employed to control pests on fruit farms while leaving
1584-595: The new foxes became more tame, allowing themselves to be petted, whimpering to get attention and sniffing and licking their caretakers. Foxes are among the comparatively few mammals which have been able to adapt themselves to a certain degree to living in urban (mostly suburban) human environments. Their omnivorous diet allows them to survive on discarded food waste , and their skittish and often nocturnal nature means that they are often able to avoid detection, despite their larger size. Urban foxes have been identified as threats to cats and small dogs, and for this reason there
1628-559: The prey's neck and shake it until it is dead or can be readily disemboweled. The gray fox is one of only two canine species known to regularly climb trees; the other is the raccoon dog . The male fox's scrotum is held up close to the body with the testes inside even after they descend. Like other canines, the male fox has a baculum , or penile bone. The testes of red foxes are smaller than those of Arctic foxes. Sperm formation in red foxes begins in August–September, with
1672-653: The pups. They communicate by barking, purring, yapping and squeaking. Pups remain in the family even after a new litter is born. The pups are weaned at the age of 61 to 70 days. Adults rear pups until they are around 16 to 17 weeks old. The oldest captive male fennec fox was 14 years old, and the oldest female 13 years. Captive fennec foxes are susceptible to canine distemper virus , displaying fever, mucopurulent ocular discharge, diarrhea , severe emaciation , seizures, generalized ataxia , severe dehydration , brain congestion, gastric ulcers and death. Stress because of capture and long-distance transportation are thought to be
1716-682: The sand for small vertebrates and insects . Some individuals were observed to bury prey for later consumption and searching for food in the vicinity of human settlements. In the Algerian Sahara, 114 scat samples were collected that contained more than 400 insects, plant fragments and date palm ( Phoenix dactylifera ) fruits, remains of birds, mammals, squamata and insects. Fennec foxes mate for life. Captive fennec foxes reach sexual maturity at around nine months and mate between January and April. Female fennec foxes are in estrus for an average of 24 hours and usually breed once per year;
1760-850: The testicles attaining their greatest weight in December–February. Vixens are in heat for one to six days, making their reproductive cycle twelve months long. As with other canines, the ova are shed during estrus without the need for the stimulation of copulating. Once the egg is fertilized, the vixen enters a period of gestation that can last from 52 to 53 days. Foxes tend to have an average litter size of four to five with an 80 percent success rate in becoming pregnant. Litter sizes can vary greatly according to species and environment – the Arctic fox , for example, can have up to eleven kits. The vixen usually has six or eight mammae . Each teat has 8 to 20 lactiferous ducts , which connect
1804-411: The underside. Fennec foxes (and other species of fox adapted to life in the desert, such as kit foxes ), for example, have large ears and short fur to aid in keeping the body cool. Arctic foxes , on the other hand, have tiny ears and short limbs as well as thick, insulating fur, which aid in keeping the body warm. Red foxes , by contrast, have a typical auburn pelt , the tail normally ending with

1848-476: The wild population to breed them in captivity until they had enough foxes to release back into the wild. Nonnative grazers were also removed so that native plants would be able to grow back to their natural height, thereby providing adequate cover and protection for the foxes against golden eagles. Darwin's fox was considered critically endangered because of their small known population of 250 mature individuals as well as their restricted distribution. However,
1892-513: The wild, the typical lifespan of a fox is one to three years, although individuals may live up to ten years. Unlike many canids, foxes are not always pack animals. Typically, they live in small family groups, but some (such as Arctic foxes ) are known to be solitary. Foxes are omnivores . Their diet is made up primarily of invertebrates such as insects and small vertebrates such as reptiles and birds. They may also eat eggs and vegetation. Many species are generalist predators, but some (such as
