water rat, any of 18 species of amphibious carnivorous rodents. They exhibit many adaptations associated with hunting in water for food and burrowing along streams, rivers, and lakes. The eyes are small, the nostrils can be closed to keep water out, and the external portion of the ears is either small and furry or absent. Highly sensitive whiskers ...
One of the smallest species is a South American fish-eating rat (Neusticomys monticolus) with a body length of 10 to 12 cm (4 to nearly 5 inches) and a tail of about the same length. The golden-bellied water rat (Hydromys chrysogaster) of Australia and New Guinea is the largest, with a body 20 to 39 cm long and a slightly shorter tail (20 to 33 cm). Living by freshwater lakes, estuaries, and rivers and in coastal mangrove swamps, it is tolerant of heavily polluted aquatic habitats. Its prey includes a variety of invertebrates, such as large aquatic insects, snails, mussels, crabs, and crayfish. Vertebrates taken include fish, frogs, turtles, young and adult birds, bird eggs, bats, and mice. The other 17 species typically require clear, unpolluted freshwater streams. The animals’ diet consists primarily of a variety of aquatic insects, but they also eat crustaceans and occasionally small fish. All water rats locate prey underwater by touch with their sensitive whiskers. Most are adept swimmers and aggressive underwater predators, but the African water rat (Colomys goslingi) wades through shallow water or sits at the water’s edge with its muzzle submerged; it is reported to eat some terrestrial insects and snails. Although most water rats are nocturnal, some species are active during the day.

Water rats of the genus Hydromys live in the mountains and coastal lowlands of Australia, New Guinea, and some nearby islands. The earless water rat (Crossomys moncktoni) inhabits mountains of eastern New Guinea, where it prefers cold, fast-flowing streams bordered by tropical forest or grass. The African water rat is also found along streams bordered by tropical forest. The 11 water rats of the Western Hemisphere are found from southern Mexico into South America, where they typically live along streams in rainforests from sea level upward to mountain pastures above the tree line.
Although all water rats are members of the mouse family (Muridae), they belong to two different subfamilies. The genera Hydromys, Crossomys, and Colomys are classified in the subfamily Murinae (Old World mice and rats), whereas the American species are members of the subfamily Sigmodontinae (New World mice and rats). No water rats exist in the Asian tropics or at nontropical latitudes. Instead, carnivorous amphibious shrews and moles occupy the water rat’s ecological niche. The European water voles (genus Arvicola) are sometimes called water rats.

The Water-rat is one of Australia's largest rodents and is usually found near permanent bodies of water. Identification. Well adapted to aquatic life with its webbed hind feet and waterproof coat, the Water-rat can be identified by its large size and long tail with a white tip.
When all you've seen is a flash of brown fur, it can be hard to know whether it was a water vole or a rat. So how do you tell rats and water voles apart?
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. Water voles have rounder noses than rats, deep brown fur, chubby faces and short fuzzy ears; unlike rats their tails, paws and ears are covered with hair.
