Hippos have big and heavy bodies, dark grey skin, and short legs. They do not have large tusks, as elephants do; a hippo's main defence is their extremely strong mouth. Hippos are actually strong enough to break an alligator in half with one bite, but they are usually not violent unless something attacks their babies. Hippopotamuses live in Africa. They live in and near fresh water, like lakes and riversHippopotamuses are herbivores. They live in groups. Sometimes 30 hippopotamuses will live in the same place. In daytime they will sleep in the mud and water, but at night they come out to eat grass
