The Giant Otter Shrew (Potamogale velox) is an aquatic, carnivorous tenrec that inhabits the Dzanga-Sangha tropical rainforest
of Cameroon, where it lives along streams and in swamps. It is the only member of the genus Potamogale. It is characterized
by a long, flat tail, which it uses for swimming by sideways undulation, much like a crocodile. The Giant Otter Shrew feeds
underwater on frogs, fish, crabs, and mollusks, which it locates with the thick bristles on its snout.
