Grizzly bears live in western Canada, the northwestern United States, and some areas of Europe and Asia near rivers where they can catch fish. Male grizzly bears live 22 years on average while females live 26 years on average. Grizzly bears are carnivorous and normally eat fish, sleeping at night and hunting during the day, though they hibernate in winter by sleeping for the entire season. Grizzly bears can weigh up to 675 kilos. They have keen senses of smell and hearing but poorer vision over long distances.
