Aonyx
''Aonyx'' is a genus of otters, containing three species, the African clawless otter, the Congo clawless otter, and the Asian small-clawed otter. The word ''aonyx'' means "clawless", derived from the prefix '' a-'' ("without") and ''onyx'' ("claw/hoof"). Species Three species are currently recognised: Zoologists differ as to whether or not to include the Asian small-clawed otter in this genus, or in its own genus '' Amblonyx''. They also differ as to whether the Congo clawless otter is a species, or is conspecific Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species.

Aonyx Cinereus
The Asian small-clawed otter (''Aonyx cinereus''), also known as the oriental small-clawed otter and the small-clawed otter, is an otter species native to South and Southeast Asia. It has short claws that do not extend beyond the pads of its webbed digits. With a total body length of , it is the smallest otter species in the world. The Asian small-clawed otter lives in riverine habitats, freshwater wetlands and mangrove swamps. It feeds on molluscs, crabs and other small aquatic animals. It lives in pairs, but was also observed in family groups with up to 12 individuals. It is listed as Vulnerable on the IUCN Red List, and is threatened by habitat loss, pollution, and in some areas also by hunting. Taxonomy ''Lutra cinerea'' was the scientific name proposed by Johann Karl Wilhelm Illiger in 1815 for an otter collected in Batavia. In the 19th and 20th centuries, several zoological specimens were described: *''Lutra concolor'' proposed by Constantine Samuel Rafinesque in ...

African Clawless Otter
The African clawless otter (''Aonyx capensis''), also known as the Cape clawless otter or groot otter, is the second-largest freshwater otter species. It inhabits permanent water bodies in savannah and lowland forest areas through most of sub-Saharan Africa. It is characterised by partly webbed and clawless feet, from which their name is derived. The word 'aonyx' means clawless, derived from the prefix a- ("without") and onyx ("claw/hoof"). Taxonomy ''Aonyx capensis'' is a member of the weasel family (Mustelidae) and of the order Carnivora. The earliest known species of otter, ''Potamotherium valetoni'', occurred in the upper Oligocene of Europe: ''A. capensis'' first appears in the fossil record during the Pleistocene. ''Aonyx'' is closely related to the extinct giant Sardinian otter, ''Megalenhydris''. Subspecies ''Mammal Species of the World'' lists six subspecies of the African clawless otter: * ''A. c. capensis'' (Schinz, 1821) * ''A. c. hindei'' (Thomas, 1905) * ''A. c. me ...

Otter
Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic, or marine, with diets based on fish and invertebrates. Lutrinae is a branch of the Mustelidae family, which also includes weasels, badgers, mink, and wolverines, among other animals. Etymology The word ''otter'' derives from the Old English word or . This, and cognate words in other Indo-European languages, ultimately stem from the Proto-Indo-European language root , which also gave rise to the English word "water". Terminology An otter's den is called a holt or couch. Male otters are called dogs or boars, females are called bitches or sows, and their offspring are called pups or cubs. The collective nouns for otters are bevy, family, lodge, romp (being descriptive of their often playful nature) or, when in water, raft. The feces of otters are typically identified by their distinctive aroma, the smell of which has been described as ranging from fres ...

Mammal Genera
There are currently 1,258 genera, 156 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''.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. 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: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Martin Hinton
Martin Alister Campbell Hinton FRS (29 June 1883 – 3 October 1961) was a British zoologist. Career Hinton joined the staff of the Natural History Museum in 1910, working on mammals, in particular rodent Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are roden ...s. He became Deputy Keeper of Zoology in 1927 and Keeper in 1936, retiring in 1945. Hinton is among those associated with the Piltdown Man hoax, a composite of an altered human skull and ape jawbone planted, and subsequently 'discovered', at a dig in Piltdown, England, and presented as a missing link between man and ape. A trunk belonging to Hinton left in storage at the Natural History Museum and found in 1970 contained animal bones and teeth carved and stained in a manner similar to the Piltdown finds, and raising question ...
