The marsh mongoose or water mongoose (Atilax paludinosus) is a medium-sized mammal, but a large mongoose. Its weight can range from 2 to 5.5 kg (4.4 to 12.1 lb), with an average range of 2.5 to 4.1 kg (5.5 to 9.0 lb). From the head to the base of the tail, these animals range from 44 to 62 cm (17 to 24 in), with the tail adding 25–36 cm (9.8–14.2 in). It is a member of the mongoose family and the only member of its genus. Atilax paludinosus is found throughout sub-Saharan Africa, with a preference for permanent freshwater habitats bordered by dense vegetation, such as marshes, reed beds, and estuaries (though sightings have been recorded in hilly areas with little or no aquatic wildlife presence). The marsh mongoose is an important member of the community of animals inhabiting the papyrus swamps, where deoxygenated water limits aquatic life to various air-breathing fish, frogs, insect larvae, snails, and mammals.
