The American Bison, also called Buffalo and North America's heaviest land animal, is not a true buffalo (like the Asian Water Buffalo). It is a little heavier than its European cousin above and has much shorter horns, a far shorter tail and much shaggier, longer hair on its neck/shoulders. Both Bisons have some capability to interbreed with the largest Asian wild cattle, the Gaur, and with the Yak and so are sometimes put in the same genus, Bos, rather than their own genus, Bison.
