Bison are very large animals that can run very fast. Irrespective of their size, they can run up to 55 km per hour. They possess humped shoulders along with short-sized legs which have hair all over them.
Also, they possess an elongated tail with a hairy end that is known as a tuft. Other than that, their coat is very much thick which provides them warmth in cooler temperatures. In the warm weather, they shade their long hairs to keep them cool.
