Anatomy
Bears range in size form 25 kg to up to 800 kg. Males are larger than females, up to twice their size. Bears have very short tails, small rounded ears, and small eyes. Most species have long rough fur. The fur can range in color from white to a dark brown and even black. Bears have forty-two teeth, except the sloth bear, which has only forty. Bear have four kinds of teeth: incisors, canines, premolars, and molars. The height of a bear can be 2 ft to up to 6ft. A bear's length can range from 3ft to 10ft. Bear can also reach speeds up to 30 mph.
Reproduction
The bear’s courtship period is very brief. Bears reproduce once a year. A bear’s liter will consist of one to three cubs and the cubs will stay with their mother for three years. The cubs will feed on milk for the first three months and after that, they will go hunting with their mother. The cubs will reach sexual maturity in about seven years. Bears are very solitary animals. They are only around other bears when they mate and when a mother has cubs. Bears are really good parents. A bear is also very protective over its young. Bears will attack other animals, including humans if they feel their cubs will be harmed.
Ecology
Bears live all around the world. They live from the tropics to the arctic. Most of the bears we know live in forests or meadows. Bears are mainly omnivorous except the polar bears. Bears will travel long distances for food. Their diet consists mostly of plants. Bears will eat berries, bees, wasps, and small rodents. They also eat big game such as elk, seal, moose calves or smaller mammals, and salmon during certain parts of the year. But commonly, however, they can only catch the newborn.
Bears live 50 to 300 square miles apart form each other. Many bears that live in the northern regions hibernate. When a bear hibernates the heart rate slows down and there body temperature drops a few degrees. They do not normally wake up during hibernation. During this period of time, bears will not eat or drink.
