The Porcupine has long strands of brown hair with thousands of quills inside. The porcupine has a small face, small ears, short legs and a thick, small tail. Its flat feet and sharp, rounded claws make it well adapted to climbing trees. Porcupines rely heavily on smell as they are short-sighted. Porcupines stick close to the trees. Beyond forests, you may find them alongside river undergrowth and maybe in the trees by a rocky ledge. They live in dens found in rock piles, caves, fallen logs and trees.
