Unlike the large, heavy porcupines many people imagine, this species is compact and lightweight, perfectly suited for life in trees. Its body is covered in a mix of coarse hair and short, sharp quills that provide protection while still allowing flexibility. The quills are not as long or dramatic as those of larger porcupines, giving it a softer, shaggy appearance. As its name suggests, the tail is dark and covered with bristly hair, helping distinguish it from other dwarf porcupines.

This porcupine is strongly adapted to an arboreal lifestyle, spending most of its life in the forest canopy. It has strong claws and gripping feet that allow it to climb trunks and move carefully along branches. The tail, while not fully prehensile like that of some tree-dwelling animals, helps with balance and stability when navigating narrow perches. The black-tailed hairy dwarf porcupine is mostly nocturnal, becoming active at night to forage and move quietly through the trees. During the day, it rests in tree hollows, dense foliage, or vine tangles where it is well hidden from predators.

Its diet consists mainly of plant material, including leaves, bark, fruits, seeds, and sometimes flowers. With strong incisors, it gnaws through tough plant matter that many animals cannot eat. By feeding on a variety of plants, the porcupine helps shape forest vegetation and spread seeds. Although slow-moving compared to many mammals, it relies on caution, camouflage, and its protective quills rather than speed to stay safe. When threatened, it may freeze in place or position its back toward danger, making its quills the first line of defense.
