Bears, scientifically classified within the Ursidae family, are a group of eight mammalian species. The black bear, brown bear and polar bear make up the genus Ursus, with the polar bear being the largest species of bear in the world. Bears are carnivorous or omnivorous and hibernate to varying degrees, though the Giant Panda does not hibernate and eats mostly bamboo.
Bears are found across Europe, Asia, North America and South America. The sun bear of South-East Asia is the world's smallest bear, and the spectacled bear is the only bear found in South America. Polar bears are found at the Arctic, while black and brown bears inhabit North America and Eurasia.
