The European water vole ( Arvicola amphibius) or northern water vole, is a semi-aquatic rodent. It is often informally called the water rat, though it only superficially resembles a true rat. [3] .
Habitat and distribution. The water rat is generally found in permanent fresh or brackish water, including freshwater lakes, streams, swamps, dams and urban rivers. It is one of only two Australian mammals living in fresh water (the other is the platypus).
Muskrats spend most of their time in the water and can swim underwater for 12 to 17 minutes. They live in families of a male and female pair and their young. They build nests to protect themselves from the cold and predators, often burrowed into the bank with an underwater entrance.
Rakali, previously known as Australia’s ‘water rat’, is an important species in Australia’s aquatic ecosystems. The largest of all Australian native rodents, rakali can be found anywhere in Australia where there is water all year round; the species’ only habitat requirement is clean water and plenty of vegetation.
The Water-rat generally occurs in permanent fresh or brackish water, although it can also be found in marine environments, including coastal mangroves in New Guinea (Flannery 1995). The species occupies a wide variety of freshwater habitats, from subalpine streams and other inland waterways to lakes, swamps, and farm dams.
