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 its own species, or conspecific with the African clawless otter.
