Peter's Climbing Rat is a large rodent with a long, naked tail and reddish-brown back. It is active at night and around dawn in forests.
Its back ranges from reddish brown to light brown, and its underside is whitish. The naked tail is nearly as long as the head and body, with a dark proximal section and a white tip.
It is arboreal and active at night and around dawn. It moves through branches and vines in tropical forest and eats mostly seeds, as well as fruit.
