Hydromys chrysogaster (Rakali or Water Rat)
The Australian Water-rat (Hydromys chrysogaster) is a genuine native rodent that was a natural part of our environment long before its pest cousins - the black rat and brown rat - arrived with the early colonists. The Water-rat (also known as Rakali) has a thick coat of waterproof, soft fur, dense whiskers, blunt muzzle, partly webbed hind feet and furry tail. It is black to brown in colour with an orange to white belly, and dark tail with a white tip.
Most active at dusk, but can be active anytime of day. Feed on a variety of primarily animal foods including fish, crustaceans, shellfish and some vertebrates. They have learnt to eat the toxic Cane Toad by flipping it over on its back to avoid the poisonous shoulder glands. They live in a burrow on the low banks of waterways.
They have been protected since 1938; before then they were killed as a nuisance animal and hunted for their soft fur. Widespread in permanent water bodies of Australia, New Guinea and offshore Islands. As it is widespread it has various Indigenous names according to the local linguistic group or area.
