| Bears (family Ursidae) are large mammals in the order Carnivora. Bears are classified as caniforms, or doglike carnivorans, with the pinnipeds being their closest living relatives. Although there are only eight living species of bear, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. Common characteristics of modern bears include a large body with stocky legs, a long snout, shaggy hair, paws with five nonretractile claws, and a short tail. While the polar bear is mostly carnivorous and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous, with largely varied diets including both plants and animals. Common characteristics of bears include a short tail, acute senses of smell and hearing, a snubbed nose, five non-retractable claws per paw, and long, dense, shaggy fur. Bears have large bodies and powerful limbs. They are capable of standing up on their hind legs. They have broad paws, long snouts, and round ears. Their teeth are bared for defense and used as tools, depending on the diet of the bear. Their claws are used for ripping, digging, and catching. Bears are generally more robust and stockier than other land carnivorans. Polar bears are the longest type, and in fact one of the largest extant carnivores, though brown bears are the heaviest.[citation needed] Sun bears are the smallest, only the size of a large dog. Some of the larger species, such as the polar bear and the grizzly bear, are dangerous to humans, especially in areas where they have become used to people. For the most part, bears are shy and are easily frightened of humans. They will, however, defend their cubs ferociously if a situation calls for it. The bear's courtship period is very brief. Bears reproduce seasonally, usually after a period of inactivity similar to hibernation. Cubs are born toothless, blind, and bald. The cubs of brown bears, usually born in litters of 1–3, will typically stay with the mother for two full seasons. They feed on their mother's milk through the duration of their relationship with their mother, although as the cubs continue to grow, nursing becomes less frequent and learn to begin hunting with the mother. They will remain with the mother for approximately three years, until she enters the next cycle of estrus and drives the cubs off. Bears will reach sexual maturity in five to seven years. Bears are generally solitary creatures and will not stay close together for long periods of time. Exceptions have been regularly observed; siblings recently on their own and sub-adult bears of similar age and status will spend a significant amount of time in informal social groups. |
