Bears are mammals known for their massive bulk, strong bodies, and loping gate. Though not commonly seen in the wild, bears are not as elusive as other large, feline predators, and are often spotted by hikers in mountainous areas.
Most bears have two layers of fur - a shorter, closer one that helps keep their bodies warm and a layer of longer hair to wick away water. Bears are also bow-legged, which gives them better grip on the ground and helps them balance.
Some bears can run up to 30 miles per hour - fast enough to catch a horse or other swift prey attempting to run away. Most bears are omnivores, meaning they eat both plants and animals.
A hibernating bear is able to slow down its heartbeat up to 75 percent - a remarkable and strange miracle of nature that allows the bear to sleep for months without needing food or water to keep alive.
