BLACK BEAR SKULL

Black Bear Skull Replica. Ursidae americanus Forests of N America and upper Mexico. Size 274mm/10.8in.

The American Black Bear usually ranges in length from 150 to 180 cm (59 to 72 inches) and typically stands about 80 to 95 cm (31 to 37 inches) at the shoulder. Standing up on its hind feet, a black bear can be up to 7 feet tall[2]. Males are 33% larger than females.[3] Females weigh between 40 and 180 kg (90 and 400 pounds); males weigh between 115 and 275 kg (250 and 600 pounds) [1]. Adult black bears seldom exceed 300 kg (660 pounds) [2] but exceptionally large males have been recorded from the wild at up to 240 cm (95 inches) long and at least 365 kg (800 pounds). The biggest American black bear ever recorded was a male from North Carolina that weigh 880 lbs (400 kilograms)[4]. Cubs usually weigh 200 to 450 g (between 7 ounces and 1 pound) at birth. The adult has small eyes, rounded ears, a long snout, a large body, and a short tail. It has an excellent sense of smell. Though they generally have shaggy black hair, the coat can vary in color from white through chocolate-brown, cinnamon-brown and blonde (found mostly west of the Mississippi River), to black in the east (the same is generally true in Canada, the border being between Manitoba and Ontario). They occasionally have a slight V-shaped white chest blaze. The tail is 4.8 inches long.[3]

Although black bears can stand and walk on their hind legs it is more normal for them to walk on all fours. When they do stand, it is usually to get a better scent or to look at something. Their characteristic shuffling gait results from their plantigrade (flat-footed) walk, with the hind legs slightly longer than the forelegs. Another reason for the apparent shuffle is that they commonly walk with a pacing gait. Unlike many quadrupeds, the legs on one side move together instead of alternating, much like a pacer horse. Each paw has five long, strong claws used for tearing, digging, and climbing.
