Bison and buffalo are two animals that roam in the Midwest. They look very similar and are often confused for one another. The buffalo is probably the term used more often to describe both of these animals. Many Native Americans hunted buffalo in the west, and the word used to describe the animals that they used for clothing and shelter was buffalo and not bison.
The buffalo is longer, and the bison is sharper. The buffalo came from Asia and Africa, whereas ironically the bison came from North America, South America, and Europe. There are far more buffalo walking around the world compared to bison. The bison only has two million in population and one hundred fifty million buffalo.
