Description

The Andean porcupine is a medium-sized porcupine with a head-and-body length of between and a tail length of between . A fully grown adult weighs in the region of . The nose is pink and large, and the eyes are small. The body is spiny all over, the evenly spaced spines being dark with yellowish tips in the animal's mid section. The tail tapers from a broad base and is prehensile. This porcupine could be confused with the

(''Sphiggurus mexicanus''), but that species has long black hair which largely conceals the spines while the Andean is more obviously spiny.

Ecology

The ecology of this species is little known. Its behaviour is likely to resemble that of its close relatives in being nocturnal and arboreal, and feeding on fruit and leaves.
