Size	Brown bears and polar bears are the largest bears, some growing to a length of 2 m (7 ft) or more and weighing 800 kg (1,760 lb). Sun bears are the smallest type of bear, growing about 1.5 m (5 ft) in length and weighing no more than 66 kg (146 lb).
Feeding Habits	Bears are classified as carnivores, or meat eaters, although different species vary widely in their feeding habits. Polar bears feed largely on seals, while other bears are generally omnivorous, eating plants, fruits, nuts, insects, fish, birds, and small to large mammals.
Offspring	Females give birth to litters of one to three cubs after a gestation of seven to nine months, depending on the species.
Lifespan	About 25 to 40 years.
Did You Know	Bears have a keen sense of smell that is seven times more powerful than that of dogs.
	Bears have an excellent memory that helps them return from afar to an abundant food location year after year.
	After bears mate, the bear embryo undergoes delayed implantation, in which it halts development and becomes inactive for as long as six months before implanting in the mother's uterus.
	Bear attacks are extremely rare and most result when a human surprises a bear, provoking it to respond defensively. have you ever provoke a bear and what was the respond of the bear?  answer  this question.
