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:[10][11]

Image Scientific name Common name Distribution
Aonyx capensis, male, Shamvura.jpg Aonyx capensis African clawless otter also known as the Cape clawless otter sub-Saharan Africa
Aonyx Congicus.jpg Aonyx congicus Congo clawless otter, also known as the Cameroon clawless otter, and formerly considered a subspecies of the African clawless otter Cameroon, Republic of the Congo, Democratic Republic of the Congo, Gabon, and possibly Angola, Burundi, Central African Republic, Equatorial Guinea, Nigeria, Rwanda, or Uganda.
Water Animal.jpg Aonyx cinereus Asian small-clawed otter, also known as the oriental small-clawed otter South and Southeast Asia.

Zoologists differ as to whether or not to include the Asian small-clawed otter in this genus, or in its own genus Amblonyx.[12][13] They also differ as to whether the Congo clawless otter is its own species, or conspecific with the African clawless otter.[14][15]
Notes

Type species by subsequent designation (Palmer 1904).[1]
