A swimming polar bear can jump 8 ft. (2.4 m) out of the water to surprise a seal.
A polar bear’s stomach can hold 150 lbs. (68 kg) of meat.
Panda bears have an extra “thumb” (which is actually an extra-large wrist bone) just for holding onto bamboo stalks. A panda bear can eat over 45 lbs. (20.4 kg) of bamboo per day.
The giant panda has a large head for its body. Scientists believe this is because it needs a strong jaw and neck muscles to eat bamboo, which makes up 99% of its diet. The remaining 1% consists of insects on the bamboo and dead meat that the panda may find.
Sloth bears’ favorite food is termites. These bears have no front teeth, so they easily suck out insects from their nests like a vacuum cleaner. They can also seal their nostrils for better suction.
Bears have been known to eat almost anything, including snowmobile seats, engine oil, and rubber boots.
Lumber companies felt they had no choice but to kill the black bears in Washington State that were eating the bark from trees. However, once someone thought to put piles of food in the forest, the bears stopped eating the trees, and were happy to eat the free food.

About 98% of the grizzly bear population in the U.S. lives in Alaska.
A polar bear can swim up to 100 miles without resting.
Bears can see almost as well as humans, and they can hear a little better. But they can smell much better. In fact, a bear’s sense of smell is around 100 times greater than a human’s. Polar bears can track down an odor from 20 miles (32 km) away. They can smell a dead seal under 3 feet of solid ice.
