How to identify New World porcupine
The New World porcupine has shaggy brown-grey fur with striking yellowish to white quills that protrude from the coat like long needles. The dense pads of quills on its back, tail and flanks are particularly noticeable and sometimes shimmer in the light.
With a body length of around 60 to 90 centimetres and a broad, bushy tail, the New World porcupine appears rounded and lumbering. Compared with other rodents, its compact silhouette with short legs and a small head radiates calm and self-sufficiency.
