The genera Melursus and Helarctos are sometimes also included in Ursus. The Asiatic black bear and the polar bear used to be placed in their own genera, Selenarctos and Thalarctos; these names have since been reduced in rank to subgenera rank.

A number of hybrids have been bred between American black, brown, and polar bears (see Ursid hybrids).
