The
grizzly bear (
Ursus arctos ssp.) is any North American morphological form or
subspecies of
brown bear, including the mainland
grizzly (
Ursus arctos horribilis),
Kodiak bear (
U. a. middendorffi),
peninsular grizzly (
U. a. gyas), and the recently extinct
California grizzly (
U. a. californicus†) and
Mexican grizzly bear (
U. a. nelsoni†). Scientists do not use the name grizzly bear but call it the
North American brown bear. (See
brown bear for a discussion of brown bears outside of North America). It should not be confused with the black grizzly or
Ussuri brown bear (
U. a. lasiotus) which is another giant brown bear inhabiting Russia, Northern China, and Korea.
