  • A small, omnivorous, mainly nocturnal mammal with hairs on the back and sides that are hollow and stiffened with keratin to form sharp spines. If the animal is disturbed it rolls into a ball, with its spines on the outside and its vulnerable head and belly safely inside. There are five genera with 17 species found in parts of Europe, Asia, and North America, and introduced in New Zealand.
