There's no animal scientifically known as a "Leather Buffalo". This term likely refers to the American Bison (Bison bison).

Here's why:

* Leather is a material, not a species.

* Buffalo is a common name for several different animals, most notably the American Bison.

* The American Bison's hide was historically used to make leather goods, hence the possible association.
