Prehensile-tailed porcupine. Widely distributed across several South American countries, it lives arboreally in lowland tropical rainforests and dry forests. Body length about 30–60 cm; the tail accounts for nearly half the total length and is prehensile, and it grasps branches with sharply curved claws. It eats fruits and unripe seeds, bark, and leaves; it is nocturnal and primarily solitary. During the day it rests in tree cavities and frequently moves its nest. The gestation period is about 195–210 days and the young are born well developed. Currently the population is stable and it is categorized as Least Concern.
