Well, when settlers first visited the new world and witnessed bison, they thought they looked like the Cape buffalo and water buffalo from other parts of the world, so they called them buffalo, and this misnomer continues to this today.
· Bison and buffalo are often confused, especially in North America.
· A key difference between bison and buffalo is the shoulder shape and horn length.
· While Buffalo are found in Asia and Africa, Bison live in North America.
