Ambush at the River Crossing
Crocodiles lie almost submerged and explode from the water to seize animals drinking or crossing, such as the wildebeest during the Serengeti migration. They use a "death roll" to tear off pieces of prey.
Caring Mothers
The female guards her nest of eggs buried in sand, and when the hatchlings call from inside the eggs she digs them out and carries them gently in her mouth to the water. Nest temperature determines the sex of the young.
People and Crocodiles
The species is responsible for many human deaths each year, while the animals themselves were heavily hunted for skins. Populations have rebounded in many areas under protection. See American Alligator.
