There are many groups of mammals, both large and small. Here are a few of the groups you will see in our halls. Bears Most bears, with the exception of the polar bear, are omnivores. A combination of sharp and flat teeth help with their varied diet of insects, fish, berries, nuts, and small vertebrates. They may also eat carrion, which is the rotting remains of dead animals.
Bears have heavy bodies, powerful limbs, and walk on flat feet.
They have short tails and thick, shaggy fur that is usually all one color. Cats Members of the cat family are considered to be the most carnivorous of mammals. Most have a short snout that allows them to bite strongly with their front teeth. They stalk their prey and move quickly to capture it. Most cats also have retractable claws, for hunting and climbing, that they can pull inside when not in use.
