Aonyx capensis capensis
The Cape clawless otter (''Aonyx capensis capensis''), sub-species of (''A. capensis'') or generally referred to as African clawless otter is found in Sub-Saharan Africa near permanent bodies of freshwater or can be seen to occupy along the sea coast (2). The Cape clawless otter is the largest of the Old World otters and the 3rd largest of all the otters after the giant otter (''Pteronura brasiliensis'') and the sea otter (''Enhydra lutris'').〔http://www.science.smith.edu/msi/pdf/671_Aonyx_capensis.pdf〕
== Physical Description ==
The Cape clawless otter is described to have a massive body and a stout tail for an otter ranging from 72 – 91 cm in length and 12 – 21 kg.〔http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2028.2004.00526.x/epdf〕 Upper lips, sides of face, neck, throat, belly, and edge of ears are all white while the rest of the coat is a brown, chestnut color.〔 The eyes and ears are small and rounded.〔 The otter's coat is dense with hairs that can reach 25 mm in length to cover a layer of thick skin.〔 As noted by the name, the otter's toes are clawless except for digits 2, 3, and 4 of hind feet which have small grooming claws.〔 The otter's hind feet are partially webbed, but the front feet are not which marks ''A. capensis'' as having the least interdigital webbing of all otters.〔 Notably, the skull of ''A. capensis'' is quite large, housing a larger brain in relative size to its body.〔http://www.arkive.org/african-clawless-otter/aonyx-capensis/〕
