Bears are large, carnivorous mammals found in various habitats around the world. They are known for their thick fur, sharp claws, and powerful build. There are eight species of bears: American black bear, brown bear, polar bear, Asiatic black bear, sloth bear, spectacled bear, sun bear, and giant panda. Bears have a great sense of smell and are omnivores, meaning they eat both plants and animals. They are apex predators and play a vital role in the ecosystem. Many bear species are threatened or endangered due to habitat loss, poaching, and hunting.
