Hippos are big blubbery animals. They have 2 big and sharp front teeth on their upper and lower jaw. Their jaws are so strong, they can bite even the mighty nile crocodile in half. Hippos have a small tail, 2 small ears, 4-toed feet, a big head, and a fat and mostly round body. Hippos can weigh up to a ton! You wouldn't want a hippo in your home! Hippos are herbavores. That means they only eat plants. Did you know hippos are great swimmers? They live in water most of the time. Hippopotamus means "river horse" though their closest relative is the whale.
