The principal distinctions of the grizzly are its physical appearance and diet. Inhabiting interior areas such as Yellowstone or Denali , grizzlies forage for plants such as grasses, glacier lilies, whitebark pinenuts, biscuit root, horsetail, false truffles, clover, dandelions, spring-beauty and globe huckleberries.

They fish cutthroat trout from streams and eat worms, moths and ants. They also scavenge the carcasses of wolf kills and prey upon elk calves and the occasional bison.

Meanwhile, coastal brown bears have a fatty, salmon-rich diet, which is why those found along the Alaska Peninsula are the largest in the world.

While all brown bears are resourceful, opportunistic feeders, vegetation play a much smaller role in the feeding habits of bears living along the shoreline. They will, however, supplement their diet with razor, butter and steamer clams they dig up on the tidal flats, as well as sedges, flowers, roots and berries.

Because a large bulk of their diet is vegetarian, grizzlies tend to be smaller than their relatives on the coast, who feast on the bounty of salmon runs.
