They live in burrows alongside river and lake banks. Distribution. The Water-rat is found in Queensland, New South Wales, Victoria, Tasmania, South Australia, Western Australia (south-west and north), Northern Territory.
The European water vole (Arvicola amphibius) is found in most of Europe, Russia, West Asia and Kazakhstan. Habitat Water vole, Ore Mountains, Germany. In Britain, water voles live in burrows excavated within the banks of rivers, ditches, ponds, and streams.
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).
They live in burrows on the edges of rivers, lakes, estuaries and protected coastal beaches and islands – the key requirement is a permanent body of water. Rakali can even be spotted in inner cities, such as alongside the penguins at St Kilda beach pier in Melbourne!
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.
The Water-rat typically forages close to the shoreline, restricting its movements to shallow water (up to 2 m in depth). In sufficiently shallow areas, it wades through the water in search of aquatic prey, and it dives in areas of greater depth (Watts and Aslin 1981).
