This species was formerly sometimes assigned to Sphiggurus,[2] a genus no longer recognized since genetic studies showed it to be polyphyletic.[4] Its closest relatives are the Andean porcupine (Coendou quichua) and the stump-tailed porcupine (Coendou rufescens).[4]

Description

This porcupine has a pale head and a dark-coloured body. The head-and-body length ranges between about 320 and 457 mm (12.6 and 18.0 in), with a tail ranging from 200 to 358 mm (8 to 14 in). The maximum weight is about 2.6 kg (6 lb). This porcupine is covered with short yellowish spines but these are almost entirely obscured by the long black hair on the body.[5] Sometimes the spines on the shoulders and back are visible projecting through the hairs. By contrast, the head is hairless, revealing the yellowish spines, the snout is pink, broad and bulbous, and the eyes are small. The tail is prehensile, spiny and broad at the base, tapering to a point. This porcupine differs from Rothschild's porcupine (Coendou rothschildi) in that Rothschild's is more obviously spiny and lacks the hairy coat.[5]

Ecology

An arboreal species, it uses its prehensile tail to hold onto branches.[5] It is nocturnal and is usually more active on dark nights. The day is spent in a hollow tree, concealed on a leafy branch, or in highland areas, in a clump of bamboos. As it uses the same hiding place each day, a pile of droppings accumulates which produces a strong odour. The diet consists of buds, young leaves, fruits and seeds. It particularly favours fruiting trees such as Inga, Cecropia, Ficus and Brosimum. Individuals normally live alone and are silent, but in the breeding season it is more vocal, emitting screams and yowls. The female usually bears a single offspring.[5]

gollark: In many cases you just need to have *a degree* of some sort, even if it's completely pointless, because it shows... that you have the patience to do a thing for 4 years or something??
gollark: Or, well, are just short of it.
gollark: So you just have costs go up until they don't reach the limit!
gollark: I mean, if you have a government policy saying "you'll get whatever education you want, free*", the government cannot just go "we'll not buy from you if you increase the price too much".
gollark: How does *that* work?
