Which Australian mammal is commonly called the rakali?

The water rat is commonly called the rakali. It is a semi-aquatic native rodent found around rivers, lakes, wetlands and estuaries across much of Australia, as well as in parts of New Guinea.

Rakali have partly webbed hind feet, dense water-resistant fur and a broad tail that assists swimming. They hunt aquatic and shoreline prey, including fish, crustaceans, frogs, insects and small animals. They may also eat birds’ eggs and other available food.

The name “rakali” was promoted as a more respectful common name than older terminology associated with introduced rats. The animal is not the same as the introduced brown rat or black rat, both of which are widespread human commensals.

Water rats can live in urban waterways when food and cover remain available. Their presence reflects the ecological value of healthy wetlands, although they may occasionally conflict with people near fish farms or stocked waterways.
