Aquatic mammals

The nutria () or coypu () (Myocastor coypus) is an herbivorous, semiaquatic rodent from South America. Classified for a long time as the only member of the family Myocastoridae, Myocastor has since been included within Echimyidae, the family of the spiny rats. The nutria lives in burrows alongside stretches of water and feeds on river plant stems.

hypothesis about human evolution

Desmans are aquatic insectivores of the tribe Desmanini (also considered a subfamily, Desmaninae) in the mole family, Talpidae.

Micropotamogale is a genus of small, otter-like dwarf otter shrews native to riverine habitats of West African rainforests. They feed on aquatic animals and insects they can find and capture. They are afrotherian mammals most closely related to the tenrecs of Madagascar, but are not closely related to shrews or otters.

Potamogalidae is the family of otter shrews, a group of semiaquatic riverine afrotherian mammals indigenous to sub-Saharan Africa. They are most closely related to the tenrecs of Madagascar, from which they are thought to have split about 47–53 million years ago. They were formerly considered a subfamily of Tenrecidae.

mammal that lives in aquatic environments

Amphinectomys savamis, also known as the Ucayali water rat or amphibious rat, is a rodent from the Peruvian Amazon. It is placed as the only member of genus Amphinectomys in the tribe Oryzomyini of family Cricetidae. It is similar to Nectomys, but its discoverers considered it to be different enough (with more expansive interdigital webbing and a significantly broader interorbital region) to require its own genus. When it was described as a new genus in 1994, knowledge of the variation within Nectomys was much more limited than it is now, and it has been suggested that the status of the taxon
