Large mammal with big head, small rounded ears, shoulder hump and short tail. Brown shaggy fur becomes grizzled (silver-tipped) with age -- hence the name "grizzly." Height on all fours is 3 1/2 feet; body length, 6 1/2 to 7 feet. Weight ranges from 330 to 1,500 lbs., depending on food and climate. Males in an area can be twice as heavy as females. Front claws range from 3 to 5 inches, and are highly adapted to digging.
