Crocodiles are left over from the age of the dinosaurs.
Crocodiles are great hunters due to their lightening-fast reflexes.
Crocs propel themselves in water using their powerful tails and webbed feet. They are nocturnal which means they hunt mostly at night. After mating, females bury from 10 to 60 hard-shelled eggs into a nest which is either a hole dug in the ground or a mound of plants made by the mother. Crocodiles are good mothers. Most females stay near the nest and protect it from predators until the hatchlings are ready to come out.
