They are found in Africa and on the island of Madagascar.
They live in freshwater areas like; lakes, rivers, swamps, and mixed salt and fresh water (brackish) areas.
They can reach about 10 feet long (1.2 m).
They dig into dens in very cold or hot weather until temperatures get better. They allow some birds to “pick their teeth.” They open their mouths wide and let the bird pick pieces of meat from between their large teeth.
They eat mostly fish, amphibians and reptiles, but will take a big animal like an antelope, buffalo, baby hippos, or big cat, if they can. They also eat dead animals that they find (carrion).
Once they are adults, man is their only real predator.
The female digs a nest hole in a sandy bank above the high water line. There she lays about 60 eggs. She stays near the nest until they hatch in about 14 weeks and then carries the babies to the water. They stay near her in the water for protection.
They can live for 45 years in the wild.
