Rattus Villosissimus

Rattus villosissimus, the Long- haired Rat is a species of rodent in the Muridae family which is native to Australia. The Long-haired rat is well known for its population eruptions over vast areas of Australia which is the basis of its alternative common name, the Plague Rat. Most of the research on the Long-haired rat has been conducted during times of massive population fluctuations and therefore little is known about their biology in a non-eruptive period.
