Western water rat

The western water rat (Hydromys hussoni) is a semiaquatic species of rodent in the family Muridae. The Wikipedia article that serves as this entry's source says it is found in West Papua, Indonesia, and in Papua New Guinea. It is threatened by habitat loss, yet much about the species is still unknown, and it has been classified as data deficient on the IUCN Red List. The article is only a few lines long, so it gives no body measurements, habitat description, diet, lifespan or population figure. Those details are left blank here rather than guessed, and the description goes only as far as that single source supports.
