types of american bison
Bison are ungulates, meaning they have hooves. They have a hump and huge heads and shoulders, and both males and females have short, curved horns. There are two types of American Bison - the Wood Bison (Bison athabascae) and the Plains Bison (Bison bison bison). The Wood Bison is larger and heavier, with a darker coat. Long strands of hair hang between its horns and it has a thinner beard and throat mane. The Plains Bison is smaller.
