Tylomys nudicaudus

Peters’s Climbing Rat

Order: Rodentia
Family: Cricetidae


Conservation Status: Least Concern.

Peters's Climbing Rat has a fairly wide distribution, from Mexico south to southern Nicaragua. The two other climbing rats found - but not often found - in Mexico are identical except for some characters of their craniums, and may prove to be subspecies of this one. They are all very large, with long, dense, woolly fur and long, naked, scaly tails. They have short, broad feet, good for climbing, and often carry their tails loosely coiled. Even Peters's Climbing Rat is not common. It is usually found near rocks, cliffs, or caves in dense forest, and though it is usually slow-moving, it can speed along vines and branches if necessary. Like other climbing rats, it is nocturnal. Little is known about its diet, but it will enter traps baited with bananas or other fruit.

Range: Head and Body: 188-260 mm; Tail: 195-262 mm

Average: 326 g
