In a zoological context, a spine is a hard, needle-like anatomical structure. Spines are found in a wide range of animals both vertebrate and invertebrate.
In most spiny mammals, the spines are modified hairs, with a spongy center covered in a thick, hard layer of keratin, and a sharp, sometimes barbed, tip.
