Bears are a type of mammal that can be found in many parts of the world. From the tiny, silly-looking sun bear to the iconic polar bear, these animals are specially adapted to different environments, including forests, mountains, icy tundra, deserts and swamps. Though there are different types of bear, all bear species have similarities. They all have stocky, fur-covered bodies; short legs; and a round head with a long snout. Whether the word "bear" makes you think of a fierce predator or a cuddly stuffed toy, there's plenty to discover about the science behind this diverse group of mammals.
