Bison and cattle (Bos taurus) are closely related, and bison are sometimes classified as Bos bison ).
Bison are typically far larger than cows and are hairier, with larger curved horns and a characteristic hump that flat-backed cattle do not have.
There are many varieties of cows, some of which have a similar appearance to bison, while others are easily told apart.
It's believed that bison cause less trampling and erosion damage to the plains than cattle, that their diet is higher in grasses and thus less damaging to the long-term chances of the plains environment, and that bison poop functions as a natural fertilizer to their habitats.
