Adults are uniformly dark with darker crossbands on tail.Their avarage size approximately 5 m (16 ft.) with maximum size of roughly 6 m (20 ft.)They are found throughout tropical and southern Africa and Madagascar. And ı want to say some fun facts about Nıle crocodıles
1)A crocodile's ectothermic metabolism is extremely efficient. A large crocodile, which may weigh more than 900 kg (2000 lb.), can survive for long periods of time between meals!
2.
If baby crocodiles are in danger, the adult female may pick them up and flip them into her mouth or gular (throat) pouch for protection.
3.
When fish are migrating, crocs may hunt cooperatively by forming a semi-circle across the river and herding the fish. They then eat the fish that are closest to them.
4.
When young crocodiles are hatching, either parent may help them out of the egg by rolling it between their tongue and palate. This cracks the shell allowing for an easier escape.
