The Bicolor-spined Porcupine is a nocturnal mammal native to the rainforests of Colombia, Ecuador, Peru, and Venezuela. It has a dense coat of yellow-based, black-tipped spines that darken on its mid-back. Its primarily spine-free tail is fully prehensile, aiding in maneuverability.

It communicates using various sounds and primarily feeds on leaves, fruits, and bark, supplementing its diet with roots, stems, and insects. 

After a gestation period of around 200 days, the female gives birth to a single offspring, which initially has soft quills that harden within a few days.
