Bison

Finally, I've discovered the difference between European and American bisons! There you go! The American bison is in Latin Bison bison and can be also called buffalo. While the European one in Latin is Bison bonasus, or can be named also wisent! What is interesting, the term bison is used in English, French (Bison d'Europe) and German (Europäischer Bison). While the term wisent only in English and German.

P.S. It is not to be confused with the aurochs as it's a different animal, by the way.
