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. The average weight is 5.5 kilograms (male) and 4.5 kilograms (female), and their average height is 60 to 100 centimetres. They can live 10 years or more. Porcupines rely heavily on smell as they are short-sighted and stay 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. Porcupines eat a variety of shrubs, bark, water plants and anything salty.
