Bear
Bears are large mammals in the family Ursidae.
Bears are large mammals in the family Ursidae, found across forests, tundra, and Arctic regions of the Northern Hemisphere and parts of South America. Most species are omnivores, but diets and sizes vary widely.
What it is
Bears belong to the mammal family Ursidae (order Carnivora). There are eight living species, including the brown bear, American black bear, polar bear, giant panda, sun bear, sloth bear, spectacled bear, and Asian black bear. They range in size from the smaller sun bear to the massive polar bear.
Diet and habitat
Most bears are opportunistic omnivores, eating berries, nuts, grasses, insects, fish, carrion, and small mammals. Polar bears lean heavily on meat (seals), while giant pandas eat mostly bamboo. Bears inhabit forests, mountains, tundra, and coastal areas across North America, Europe, Asia, and South America (spectacled bear).
Key details
Body weight varies hugely — from under 100 kg to over 600 kg for polar bears. Lifespan depends on species and conditions; brown bears typically live 15–25 years in the wild. Bears can be dangerous if surprised or defending cubs or food.
