BISON

The Bison is a large, powerful, genus of ox-like mammals of the family Bovidae. They differ from typical cattle in being larger, with a convex forehead, large legs and a pronounced hump at the shoulders. They also have 14 pairs of ribs, where cattle have 13. The fur is coarse, and long on the head, neck and shoulders. The large head is carried low, the animal being unable to lift its head above shoulder level. Both the male and female are furnished with heavy, curved horns, those of the female being smaller than those of the male.
