Tragulus Javanicus Skeleton At Yale Peabody Museum
''Tragulus'' is a genus of even-toed ungulates in the family Tragulidae that are known as mouse-deer. In Ancient Greek τράγος (''tragos'') means a male goat, while the Latin diminutive ''–ulus'' means 'tiny'. With a weight of and a length of , they are the smallest ungulates in the world, though the largest species of mouse-deer surpass some species of ''Neotragus'' antelopes in size.Nowak, R. M. (eds) (1999). ''Walker's Mammals of the World.'' 6th edition. Johns Hopkins University Press. The mouse-deer are restricted to Southeast Asia from far Southern China (south Yunnan) to the Philippines (Balabac) and Java. Following recent taxonomic changes, several of the species in this genus are poorly known, but all are believed to be mainly nocturnal and feed on leaves, fruits, grasses, and other vegetation in the dense forest undergrowth. They are solitary or live in pairs, and the males have elongated canine teeth (neither gender has horns or antlers) that are used in fight ...

Mathurin Jacques Brisson
Mathurin Jacques Brisson (; 30 April 1723 – 23 June 1806) was a French zoologist and natural philosophy, natural philosopher. Brisson was born on 30 April 1723 at Fontenay-le-Comte in the Vendée department of western France. Note that page 141 is before page 140. His parents wished him to take ecclesiastic orders, but in 1747, he abandoned his studies, and from 1749, was employed by the wealthy French naturalist René Antoine Ferchault de Réaumur as the curator of a large private collection of objects related to natural history that de Réaumur kept at his ancestral home at Réaumur, Vendée, Réaumur in the Vendée. Originally published by F. W. Peters in 1951 as ''Die Entwicklung Der Ornithologie von Aristoteles bis zur Gegenwart''. Brisson became interested in the classification of animals and was influenced by the works of Carl Linnaeus and Jacob Theodor Klein. His book ''Le Règne animal'' was published in 1756, and the highly regarded six-volume work ''Ornithologie'' wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nocturnal
Nocturnality is a ethology, behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnality, diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing (sense), hearing, olfaction, smell, and specially adapted eyesight. Some animals, such as ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbaby, bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsier, tarsiers and some owl, owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Mathurin Jacques Brisson
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal Genera
There are currently 1,258 genera, 161 families, 27 orders, and around 5,937 recognized living species of mammal. Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families. The taxonomy represented here is a compilation of the most logical and up-to-date information on mammalian taxonomy from many sources, the main ones being '' Handbook of the Mammals of the World'' series and '' Mammal Species of the World''.

Chevrotains
Chevrotains, or mouse-deer, are small, even-toed ungulates that make up the family Tragulidae, and are the only living members of the infraorder Tragulina. The 10 extant species are placed in three genera, but several species also are known only from fossils. The extant species are found in forests in South and Southeast Asia; a single species, the water chevrotain, is found in the rainforests of Central and West Africa. In November 2019, conservation scientists announced that they had photographed silver-backed chevrotains (''Tragulus versicolor'') in a Vietnamese forest for the first time since the last confirmed sightings in 1990. They are solitary, or live in loose groupings or pairs, and feed almost exclusively on plant material. Chevrotains are the smallest hoofed mammals in the world. The Asian species weigh between , while the African chevrotain is considerably larger, at . With an average length of and an average height of , the Java mouse-deer is the smallest ...

Vietnam Mouse-deer
The Vietnam mouse-deer (''Tragulus versicolor''), also known as the silver-backed chevrotain, is an even-toed ungulate in the family Tragulidae known only from Vietnam. It was first described in 1910 by British zoologist Oldfield Thomas, who procured four specimens from Nha Trang in Annam. Little is known about its distribution and ecology. After 1910, the Vietnam mouse-deer was reported next in 1990 near Dak Rong and Buon Luoi in the Gia Lai Province. With increasing hunting pressure, habitat loss due to deforestation and no more reports of the species in the wild, the mouse-deer was feared to have gone extinct. The IUCN listed the species as Data Deficient in 2008. In 2019, a study confirmed the presence of the Vietnam mouse-deer in dry low-lying forests of southern Vietnam with camera trap evidence. The mouse-deer is characterised by a rough coat with a strange double-tone coloration unseen in other chevrotains; the front part of the body is reddish brown and contrasts str ...

Philippine Mouse-deer
The Philippine mouse-deer (''Tragulus nigricans''), also known as the Balabac chevrotain or ''pilandok'' (in Filipino), is a small, nocturnal ruminant, which is endemic to Balabac and nearby smaller islands (Bugsuk and Ramos) southwest of Palawan in the Philippines. The genus ''Tragulus'' means 'little goat' and the Philippine mouse-deer has been named so due to the horizontal pupils of the eyes. This position of the pupil allows for an increase in peripheral depth perception. It has traditionally been considered a subspecies of the greater mouse-deer (''T. napu''). In 2004, though, ''T. nigricans'' was separated from ''T. napu'' as its own species due to differences in skull morphology (skull measurements). Contrary to its common name, the Philippine mouse-deer does not belong to the true deer family ( Cervidae); it is a member of the chevrotain family, a grouping of some of the world's smallest hoofed mammals. Morphology It has a black and brown coat with white stripes on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Mouse-deer
The greater mouse-deer, greater Malay chevrotain, or napu (''Tragulus napu'') is a species of even-toed ungulate in the family Tragulidae found in Sumatra, Borneo, and smaller Malaysian and Indonesian islands, and in southern Myanmar, southern Thailand, and peninsular Malaysia. Its natural habitat is subtropical or tropical, moist, lowland forest. Etymology ''Tragos'' is Greek for "goat" and ''–ulus'' in Latin means "tiny". ''Napu'' is a local name, from Malay ''napuh''. The name "mouse-deer" refers to its small size and does not imply that it is a true deer. It is called "greater" because it is larger than other ''Tragulus'' species. Morphology The greater mouse-deer is an even-toed ungulate. Although very small for an ungulate, the greater mouse-deer is one of the largest members of its genus. It is rivalled in size by Williamson's mouse-deer. It weighs . Its head-and-body length is and its tail length is . Its shoulder height is about It has a small, triangular hea ...

Lesser Mouse-deer
The lesser mouse-deer, lesser Malay chevrotain, or kanchil (''Tragulus kanchil'') is a species of even-toed ungulate in the family Tragulidae. Distribution The lesser mouse-deer is found widely across Southeast Asia in Indochina, Myanmar (Kra Isthmus), Brunei, Cambodia, China (Southern Yunnan), Indonesia (Kalimantan, Sumatra and many other small islands), Laos, Malaysia (Peninsular Malaysia, Sarawak and many other small islands), Singapore, Thailand, and Vietnam. Description It is one of the smallest known hoofed mammals, its mature size being as little as 45 cm (18 inches) and 2 kg (4.4 lb) and related to the even smaller Java mouse-deer. It is threatened by predation by feral dogs. Through further research it is also discovered that the creatures who were initially believed to be nocturnal actually conduct their activities during the day. Also, though many births occur in May, November or December, the females are able to reproduce throughout the year (Kus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Mouse-deer
The Java mouse-deer (''Tragulus javanicus'') is a species of even-toed ungulate in the family Tragulidae. When it reaches maturity it is about the size of a rabbit, making it the smallest living ungulate. It is found in forests in Java and perhaps Bali, although sightings there have not been verified. This mouse-deer is depicted in Indonesian folklore as '' Sang Kancil''. Nomenclature The Java mouse-deer has many common names, including Javan chevrotain, Javan mousdeer, or Java Mouse Deer.Facts about Lesser Mouse Deer (Tragulus javanicus) - Encyclopedia of Life.
