Black-tailed mosaic-tailed rat

The black-tailed mosaic-tailed rat, or black-tailed melomys (Melomys rufescens), is a species of rodent in the family Muridae. The Wikipedia article that serves as this entry's source says it is found through much of New Guinea and on some nearby islands, namely Salawati and Misool in Indonesia and the Bismarck Archipelago, including New Britain and New Ireland. It is known as alks in the Kalam language of Papua New Guinea. The species is common in disturbed habitat and in primary forest at elevations up to 2,400 metres, and it is largely arboreal. The article gives no body measurements, diet, lifespan, population figure or conservation category, so those details are left blank here rather than guessed.
