63-422: Naja is a genus of venomous elapid snakes commonly known as cobras (or " true cobras "). Members of the genus Naja are the most widespread and the most widely recognized as "true" cobras. Various species occur in regions throughout Africa , Southwest Asia , South Asia , and Southeast Asia . Several other elapid species are also called "cobras", such as the king cobra and the rinkhals , but neither

126-418: A hypodermic needle ), have a shortened, rounded opening in the front surface, which ejects the venom forward, out of the mouth. While typically referred to as "spitting", the action is more like squirting. The range and accuracy with which they can shoot their venom varies from species to species, but it is used primarily as a defense mechanism. The venom has little or no effect on unbroken skin, but if it enters

189-513: A basal lineage to all species. Shi, Vogel, Chen, & Ding, 2022 Genus The composition of a genus is determined by taxonomists . The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: Moreover, genera should be composed of phylogenetic units of

252-510: A characteristic ability to raise the front quarters of their bodies off the ground and flatten their necks to appear larger to a potential predator. Fang structure is variable; all species except the Indian cobra ( Naja naja ) and Caspian cobra ( Naja oxiana ) have some degree of adaptation to spitting . All species in the genus Naja are capable of delivering a fatal bite to a human. Most species have strongly neurotoxic venom, which attacks

315-448: A high potency of 0.22 mg/kg. Other highly venomous species are the forest cobras and/or water cobras ( Boulengerina subgenus). The murine intraperitoneal LD 50 of Naja annulata and Naja christyi venoms were 0.143 mg/kg (range of 0.131 mg/kg to 0.156 mg/kg) and 0.120 mg/kg, respectively. Christensen (1968) also listed an IV LD 50 of 0.17 mg/kg for N. annulata . The Chinese cobra ( N. atra )

378-465: A keen sense of hearing. They depend on their sense of smell to locate food and avoid predators. In the wild, mice are known to build intricate burrows. These burrows have long entrances and are equipped with escape tunnels. In at least one species, the architectural design of a burrow is a genetic trait. The most common mice are murines , in the same clade as common rats . They are murids, along with gerbils and other close relatives. Researchers at

441-769: A large variety of vegetables. Despite popular belief, most mice do not have a special appetite for cheese. They will only eat cheese for lack of better options. Mice are common experimental animals in laboratory research of biology and psychology fields primarily because they are mammals , and also because they share a high degree of homology with humans. They are the most commonly used mammalian model organism , more common than rats . The mouse genome has been sequenced, and virtually all mouse genes have human homologs . The mouse has approximately 2.7 billion base pairs and 20 pairs of chromosomes. They can also be manipulated in ways that are illegal with humans, although animal rights activists often object. A knockout mouse

504-651: A later homonym of a validly published name is a nomen illegitimum or nom. illeg. ; for a full list refer to the International Code of Nomenclature for algae, fungi, and plants and the work cited above by Hawksworth, 2010. In place of the "valid taxon" in zoology, the nearest equivalent in botany is " correct name " or "current name" which can, again, differ or change with alternative taxonomic treatments or new information that results in previously accepted genera being combined or split. Prokaryote and virus codes of nomenclature also exist which serve as

567-628: A long time and redescribed as new by a range of subsequent workers, or if a range of genera previously considered separate taxa have subsequently been consolidated into one. For example, the World Register of Marine Species presently lists 8 genus-level synonyms for the sperm whale genus Physeter Linnaeus, 1758, and 13 for the bivalve genus Pecten O.F. Müller, 1776. Within the same kingdom, one generic name can apply to one genus only. However, many names have been assigned (usually unintentionally) to two or more different genera. For example,

630-460: A medically important group of snakes due to the number of bites and fatalities they cause across their geographical range. They range throughout Africa (including some parts of the Sahara where Naja haje can be found), Southwest Asia , Central Asia , South Asia , East Asia , and Southeast Asia . Roughly 30% of bites by some cobra species are dry bites, thus do not cause envenomation (a dry bite

693-403: A more plausible etymology connecting it with Sanskrit nagna , "hairless" or "naked". Naja species vary in length and most are relatively slender-bodied snakes. Most species are capable of attaining lengths of 1.84 m (6.0 ft). Maximum lengths for some of the larger species of cobras are around 3.1 m (10 ft), with the forest cobra arguably being the longest species. All have

An available (zoological) or validly published (botanical) name that has been historically applied to a genus but is not regarded as the accepted (current/valid) name for

819-481: A relatively short time. Mice are generally very docile if raised from birth and given sufficient human contact. However, certain strains have been known to be quite temperamental. Many people buy mice as companion pets. They can be playful, loving and can grow used to being handled. Like pet rats, pet mice should not be left unsupervised outside as they have many natural predators, including (but not limited to) birds, snakes, lizards, cats, and dogs. Male mice tend to have

882-524: A stronger odor than the females. However, mice are careful groomers and as pets they never need bathing. Well looked-after mice can make ideal pets. Some common mouse care products are: Mice are a staple in the diet of many small carnivores . In various countries mice are used as feed for pets such as snakes , lizards , frogs , tarantulas , and birds of prey , and many pet stores carry mice for this purpose. Such mice are sold in various sizes and with various amounts of fur. Mice without fur are easier for

945-594: A subcutaneous value of 0.2 mg/kg (0.16-0.47 mg/kg) for N. oxiana . The crude venom of N. oxiana produced the lowest known lethal dose (LCLo) of 0.005 mg/kg, the lowest among all cobra species ever recorded, derived from an individual case of envenomation by intracerebroventricular injection. The Banded water cobra 's LD 50 was estimated to be 0.17 mg/kg via IV according to Christensen (1968). The Philippine cobra ( N. philippinensis ) has an average murine LD 50 of 0.18 mg/kg IV ( Tan et al, 2019 ). Minton (1974) reported 0.14 mg/kg IV for

1008-427: A taxon; however, the names published in suppressed works are made unavailable via the relevant Opinion dealing with the work in question. In botany, similar concepts exist but with different labels. The botanical equivalent of zoology's "available name" is a validly published name . An invalidly published name is a nomen invalidum or nom. inval. ; a rejected name is a nomen rejiciendum or nom. rej. ;

1071-455: A total of c. 520,000 published names (including synonyms) as at end 2019, increasing at some 2,500 published generic names per year. "Official" registers of taxon names at all ranks, including genera, exist for a few groups only such as viruses and prokaryotes, while for others there are compendia with no "official" standing such as Index Fungorum for fungi, Index Nominum Algarum and AlgaeBase for algae, Index Nominum Genericorum and

1134-494: Is a genetically modified mouse that has had one or more of its genes made inoperable through a gene knockout . Experimental mouse model systems include mouse models of colorectal and intestinal cancer , mouse models of Down syndrome and mouse models of breast cancer metastasis . Reasons for common selection of mice are that they are small and inexpensive, have a widely varied diet, are easily maintained, and can reproduce quickly. Several generations of mice can be observed in

1197-573: Is a bite by a venomous snake that does not inject venom). Brown (1973) noted that cobras with a higher rates of 'sham strikes' tend to be more venomous, while those with a less toxic venom tend to envenomate more frequently when attempting to bite. This can vary even between specimens of the same species. This is unlike related elapids, such as those species belonging to Dendroaspis (mambas) and Bungarus (kraits), with mambas tending to almost always envenomate and kraits tending to envenomate more often than they attempt 'sham strikes'. Many factors influence

1260-406: Is a true cobra, in that they do not belong to the genus Naja , but instead each belong to monotypic genera Hemachatus (the rinkhals) and Ophiophagus (the king cobra/hamadryad). Until recently, the genus Naja had 20 to 22 species , but it has undergone several taxonomic revisions in recent years, so sources vary greatly. Wide support exists, though, for a 2009 revision that synonymised

1323-588: Is administered rapidly after envenomation. Envenomation caused by N. oxiana is much more complicated. In addition to prominent neurotoxicity, very potent cytotoxic and cardiotoxic components are in this species' venom. Local effects are marked and manifest in all cases of envenomation: severe pain, severe swelling, bruising, blistering, and tissue necrosis. Renal damage and cardiotoxicity are also clinical manifestations of envenomation caused by N. oxiana , though they are rare and secondary. The untreated mortality rate among those envenomed by N. oxiana approaches 80%,

1386-613: Is also highly venomous. Minton (1974) listed a value of LD 50 0.3 mg/kg intravenous (IV), while Lee and Tseng list a value of 0.67 mg/kg subcutaneous injection (SC). The LD 50 of the Cape cobra ( N. nivea ) according to Minton, 1974 was 0.35 mg/kg (IV) and 0.4 mg/kg (SC). The Senegalese cobra ( N. senegalensis ) has a murine LD 50 of 0.39 mg/kg (Tan et al, 2021) via IV. The Egyptian cobra ( N. haje ) of Ugandan locality had an IV LD 50 of 0.43 mg/kg (0.35–0.52 mg/kg). The Naja species are

1449-612: Is discouraged by both the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants , there are some five thousand such names in use in more than one kingdom. For instance, A list of generic homonyms (with their authorities), including both available (validly published) and selected unavailable names, has been compiled by the Interim Register of Marine and Nonmarine Genera (IRMNG). The type genus forms

1512-1606: Is generally poor among patients, so mechanical ventilation and endotracheal intubation is required. As a result, mortality among those treated for N. oxiana envenomation is still relatively high (up to 30%) compared to all other species of cobra (<1%).

Several recent taxonomic studies have revealed species not included in

1575-460: Is somewhat arbitrary. Although all species within a genus are supposed to be "similar", there are no objective criteria for grouping species into genera. There is much debate among zoologists about whether enormous, species-rich genera should be maintained, as it is extremely difficult to come up with identification keys or even character sets that distinguish all species. Hence, many taxonomists argue in favor of breaking down large genera. For instance,

1638-474: Is the type species , and the generic name is permanently associated with the type specimen of its type species. Should the specimen turn out to be assignable to another genus, the generic name linked to it becomes a junior synonym and the remaining taxa in the former genus need to be reassessed. In zoological usage, taxonomic names, including those of genera, are classified as "available" or "unavailable". Available names are those published in accordance with

1701-621: The International Code of Zoological Nomenclature ; the earliest such name for any taxon (for example, a genus) should then be selected as the " valid " (i.e., current or accepted) name for the taxon in question. Consequently, there will be more available names than valid names at any point in time; which names are currently in use depending on the judgement of taxonomists in either combining taxa described under multiple names, or splitting taxa which may bring available names previously treated as synonyms back into use. "Unavailable" names in zoology comprise names that either were not published according to

1764-824: The International Plant Names Index for plants in general, and ferns through angiosperms, respectively, and Nomenclator Zoologicus and the Index to Organism Names for zoological names. Totals for both "all names" and estimates for "accepted names" as held in the Interim Register of Marine and Nonmarine Genera (IRMNG) are broken down further in the publication by Rees et al., 2020 cited above. The accepted names estimates are as follows, broken down by kingdom: The cited ranges of uncertainty arise because IRMNG lists "uncertain" names (not researched therein) in addition to known "accepted" names;

1827-535: The murine LD 50 via intravenous injection (IV) value for Naja oxiana (Iranian specimens) was estimated to be 0.14 mg/kg (0.067-0.21 mg/kg) more potent than the sympatric Pakistani Naja naja karachiensis and Naja naja indusi found in far north and northwest India and adjacent Pakistani border areas (0.22 mg/kg), the Thai Naja kaouthia (0.2 mg/kg), and Naja philippinensis at 0.18 mg/kg (0.11-0.3 mg/kg). Latifi (1984) listed

1890-419: The nomenclature codes , which allow each species a single unique name that, for animals (including protists ), plants (also including algae and fungi ) and prokaryotes ( bacteria and archaea ), is Latin and binomial in form; this contrasts with common or vernacular names , which are non-standardized, can be non-unique, and typically also vary by country and language of usage. Except for viruses ,

1953-404: The platypus belongs to the genus Ornithorhynchus although George Shaw named it Platypus in 1799 (these two names are thus synonyms ) . However, the name Platypus had already been given to a group of ambrosia beetles by Johann Friedrich Wilhelm Herbst in 1793. A name that means two different things is a homonym . Since beetles and platypuses are both members of the kingdom Animalia,

2016-602: The Max Planck Institute of Neurobiology have confirmed that mice have a range of facial expressions. They used machine vision to spot familiar human emotions like pleasure, disgust, nausea, pain, and fear. In nature, mice are largely herbivores , consuming any kind of fruit or grain from plants. However, mice adapt well to urban areas and are known for eating almost all types of food scraps. In captivity, mice are commonly fed commercial pelleted mouse diet. These diets are nutritionally complete, but they still need

2079-579: The Philippine cobra ( N. philippinensis ) are the two cobra species with the most toxic venom based on LD 50 studies on mice. Both species cause prominent neurotoxicity and progression of life-threatening symptoms following envenomation. Death has been reported in as little as 30 minutes in cases of envenomation by both species. N. philippinensis purely neurotoxic venom causes prominent neurotoxicity with minimal local tissue damage and pain and patients respond very well to antivenom therapy if treatment

2142-626: The Philippine cobra. The Samar cobra ( Naja samarensis ), another cobra species endemic to the southern islands of the Philippines, is reported to have a LD 50 of 0.2 mg/kg, similar in potency to the monocled cobras ( Naja kaouthia ) found only in Thailand and eastern Cambodia , which also have a LD 50 of 0.2 mg/kg. The spectacled cobras that are sympatric with N. oxiana , in Pakistan and far northwest India, also have

In Victorian Britain, fried mice were still given to children as a folk remedy for bed-wetting ; while Jared Diamond reports creamed mice being used in England as a dietary supplement during Second World War rationing. Mice are a delicacy throughout eastern Zambia and northern Malawi , where they are

However, this does not typically ascend more than one or two levels: the order to which dogs and wolves belong is Carnivora ("Carnivores"). The numbers of either accepted, or all published genus names is not known precisely; Rees et al., 2020 estimate that approximately 310,000 accepted names (valid taxa) may exist, out of

2331-411: The cobra species involved. The vast majority of envenomated patients treated make quick and complete recoveries, while other envenomated patients who receive similar treatment result in fatalities. The most important factors in the difference of mortality rates among victims envenomated by cobras is the severity of the bite and which cobra species caused the envenomation. The Caspian cobra ( N. oxiana ) and

2394-493: The common house mouse ( Mus musculus ). Mice are also popular as pets . In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter. Mice are typically distinguished from rats by their size. Generally, when a muroid rodent is discovered, its common name includes the term mouse if it is smaller, or rat if it is larger. The common terms rat and mouse are not taxonomically specific. Typical mice are classified in

2457-540: The current listing in ITIS: Two recent molecular phylogenetic studies have also supported the incorporation of the species previously assigned to the genera Boulengerina and Paranaja into Naja , as both are closely related to the forest cobra ( Naja melanoleuca ). In the most comprehensive phylogenetic study to date, 5 putative new species were initially identified, of which 3 have since been named. The controversial amateur herpetologist Raymond Hoser proposed

2520-638: The differences in cases of fatality among different species within the same genus. Among cobras, the cases of fatal outcome of bites in both treated and untreated victims can be quite large. For example, mortality rates among untreated cases of envenomation by the cobras as a whole group ranges from 6.5–10% for N kaouthia . to about 80% for N. oxiana . Mortality rate for Naja atra is between 15 and 20%, 5–10% for N. nigricollis , 50% for N. nivea , 20–25% for N. naja , In cases where victims of cobra bites are medically treated using normal treatment protocol for elapid type envenomation, differences in prognosis depend on

2583-513: The eyes, it can cause a severe burning sensation and temporary or even permanent blindness if not washed out immediately and thoroughly. A recent study showed that all three spitting cobra lineages have evolved higher pain-inducing activity through increased phospholipase A2 levels, which potentiate the algesic action of the cytotoxins present in most cobra venoms. The timing of the origin of spitting in African and Asian Naja species corresponds to

2646-446: The form "author, year" in zoology, and "standard abbreviated author name" in botany. Thus in the examples above, the genus Canis would be cited in full as " Canis Linnaeus, 1758" (zoological usage), while Hibiscus , also first established by Linnaeus but in 1753, is simply " Hibiscus L." (botanical usage). Each genus should have a designated type , although in practice there is a backlog of older names without one. In zoology, this

2709-525: The genera Boulengerina and Paranaja with Naja . According to that revision, the genus Naja now includes 38 species. The origin of this genus name is from the Sanskrit nāga (with a hard "g") meaning "snake". Some hold that the Sanskrit word is cognate with English "snake", Germanic: *snēk-a- , Proto-IE : *(s)nēg-o- , but Manfred Mayrhofer calls this etymology "not credible", and suggests

2772-737: The generic name (or its abbreviated form) still forms the leading portion of the scientific name, for example, Canis lupus lupus for the Eurasian wolf subspecies, or as a botanical example, Hibiscus arnottianus ssp. immaculatus . Also, as visible in the above examples, the Latinised portions of the scientific names of genera and their included species (and infraspecies, where applicable) are, by convention, written in italics . The scientific names of virus species are descriptive, not binomial in form, and may or may not incorporate an indication of their containing genus; for example,

2835-699: The genus Mus , but the term mouse is not confined to members of Mus and can also apply to species from other genera such as the deer mouse ( Peromyscus ) . Domestic mice sold as pets often differ substantially in size from the common house mouse. This is attributable to breeding and different conditions in the wild. The best-known strain of mouse is the white lab mouse . It has more uniform traits that are appropriate to its use in research. Cats , wild dogs , foxes , birds of prey , snakes and certain kinds of arthropods have been known to prey upon mice. Despite this, mice populations remain plentiful. Due to its remarkable adaptability to almost any environment ,

2898-716: The genus Spracklandus for the African spitting cobras. Wallach et al. suggested that this name was not published according to the Code and suggested instead the recognition of four subgenera within Naja : Naja for the Asiatic cobras, Boulengerina for the African forest, water and burrowing cobras, Uraeus for the Egyptian and Cape cobra group and Afronaja for the African spitting cobras. International Commission on Zoological Nomenclature issued an opinion that it "finds no basis under

2961-597: The highest among all species within the genus Naja . Antivenom is not as effective for envenomation by this species as it is for other Asian cobras within the same region, like the Indian cobra ( N. naja ) and due to the dangerous toxicity of this species' venom, massive amounts of antivenom are often required for patients. As a result, a monovalent antivenom serum is being developed by the Razi Vaccine and Serum Research Institute in Iran. Response to treatment with antivenom

3024-633: The largest component, with 23,236 ± 5,379 accepted genus names, of which 20,845 ± 4,494 are angiosperms (superclass Angiospermae). By comparison, the 2018 annual edition of the Catalogue of Life (estimated >90% complete, for extant species in the main) contains currently 175,363 "accepted" genus names for 1,744,204 living and 59,284 extinct species, also including genus names only (no species) for some groups. The number of species in genera varies considerably among taxonomic groups. For instance, among (non-avian) reptiles , which have about 1180 genera,

3087-400: The lizard genus Anolis has been suggested to be broken down into 8 or so different genera which would bring its ~400 species to smaller, more manageable subsets. Mouse A mouse ( pl. : mice ) is a small rodent . Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is

3150-403: The most (>300) have only 1 species, ~360 have between 2 and 4 species, 260 have 5–10 species, ~200 have 11–50 species, and only 27 genera have more than 50 species. However, some insect genera such as the bee genera Lasioglossum and Andrena have over 1000 species each. The largest flowering plant genus, Astragalus , contains over 3,000 species. Which species are assigned to a genus

3213-579: The mouse is one of the most successful mammalian genera living on Earth today. In certain contexts, mice can be considered vermin . Vermin are a major source of crop damage, as they are known to cause structural damage and spread disease . Mice spread disease through their feces and are often carriers of parasites . In North America, breathing dust that has come in contact with mouse excrement has been linked to hantavirus , which may lead to hantavirus pulmonary syndrome (HPS). Primarily nocturnal animals, mice compensate for their poor eyesight with

However, a genus in one kingdom is allowed to bear a scientific name that is in use as a generic name (or the name of a taxon in another rank) in a kingdom that is governed by a different nomenclature code.

According to "Glossary" section of the zoological Code, suppressed names (per published "Opinions" of the International Commission of Zoological Nomenclature) remain available but cannot be used as the valid name for

3528-470: The same kind as other (analogous) genera. The term "genus" comes from Latin genus , a noun form cognate with gignere ('to bear; to give birth to'). The Swedish taxonomist Carl Linnaeus popularized its use in his 1753 Species Plantarum , but the French botanist Joseph Pitton de Tournefort (1656–1708) is considered "the founder of the modern concept of genera". The scientific name (or

3591-408: The scientific epithet) of a genus is also called the generic name ; in modern style guides and science, it is always capitalised. It plays a fundamental role in binomial nomenclature , the system of naming organisms , where it is combined with the scientific name of a species : see Botanical name and Specific name (zoology) . The rules for the scientific names of organisms are laid down in

3654-509: The separation of the human and chimpanzee evolutionary lineages in Africa and the arrival of Homo erectus in Asia. The authors therefore hypothesise that the arrival of bipedal, tool-using primates may have triggered the evolution of spitting in cobras. The Caspian cobra ( N. oxiana ) of Central Asia is the most venomous Naja species. According to a 2019 study by Kazemi-Lomedasht et al ,

3717-497: The specific name particular to the wolf. A botanical example would be Hibiscus arnottianus , a particular species of the genus Hibiscus native to Hawaii. The specific name is written in lower-case and may be followed by subspecies names in zoology or a variety of infraspecific names in botany . When the generic name is already known from context, it may be shortened to its initial letter, for example, C. lupus in place of Canis lupus . Where species are further subdivided,

3780-412: The standard format for a species name comprises the generic name, indicating the genus to which the species belongs, followed by the specific epithet, which (within that genus) is unique to the species. For example, the gray wolf 's scientific name is Canis lupus , with Canis ( Latin for 'dog') being the generic name shared by the wolf's close relatives and lupus (Latin for 'wolf') being

3843-403: The taxon is termed a synonym ; some authors also include unavailable names in lists of synonyms as well as available names, such as misspellings, names previously published without fulfilling all of the requirements of the relevant nomenclatural code, and rejected or suppressed names.
