Rajah spiny rat

The Rajah spiny rat, Maxomys rajah, also called the brown spiny rat, is a rodent endemic to Thailand and Malaysia, Sumatra, Borneo and adjacent islands. Its source article, drawing on Payne and colleagues in 1985, describes a medium-sized animal with brown upperparts that are darker along the midline and covered in stiff gray-brown spines, white underparts with short white spines, and a tail that is brown above and pale below. Recorded weights run from 71 to 218 grams. It lives in primary and logged-over forest, favours sandy and lowland sites, and is mostly active on the ground while occasionally climbing into the canopy. It tends to live apart from other rats, and the article notes that the immature red spiny rat is hard to tell from it.
