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").
Three species are currently recognised: [10] [11]

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 a species, or is conspecific with the African clawless otter. [14] [15] [16] [17] [18]
