Giant otter shrew

The giant otter shrew (Potamogale velox) is a semiaquatic, carnivorous tenrec.
This species, which is often mistaken for a small otter, has a slender body and a long tail. This tail is used to propel itself through the water. Mainly nocturnal and solitary, the Giant otter-shrew hunts primarily on shellfish, fish, frogs, and other freshwater animals.
