The Saltwater Crocodile is the biggest reptile in the world with the Nile Crocodile being the second. The Nile Crocodile will normally grow to over 4 metres in length. Occasionally individuals around 6 metres in length are encountered.

Crocodiles eat a wide variety of prey including mammals, birds, reptiles and fish. The catch their prey by ambushing them. They are well-known for taking large mammals like Burchell's Zebras and wildebeest as they cross, or drink from, a stretch of water. The wildebeest migration in Tanzania has been the subject of many films showing the epic struggle between crocs and wildebeest as the herds cross the river as part of their migration.

Although the larger, older individuals get preference these crocodiles are, however, quite sociable and will often be seen basking in the sun together.

Female crocodiles bury their eggs in sand and will keep nearby to guard the nest. Some animals such as the Nile Monitor seek out the nests and will try and eat the eggs if they can. Normally around 50 eggs are laid by one female.

The newly hatched crocodiles are freed from their sandy nest by the mother. She helps them escape from their shells and may even carry them to the water. Although the mother crocodile offers protection for the hatchlings they must feed themselves.
