Crocodiles are thought to be around since the time of the dinosaurs. They are solitary reptiles that live in warm quiet murky water and mainly feed on fish. They have a dark bronze colour on their bodies that are covered with scales. They move by crawling on their stomachs but can also high walk. Their nostrils, eyes and ears are situated on top of their heads so that their bodies can remain submerged in the water.
The male crocodiles are around 30 % larger than the female. Both the male and the female crocodiles reach sexual maturity after 10 years. 2 months after mating, the female lays an average of 50 eggs and buries them in the soil a meter from the water banks. Both parents-
To-be guard the eggs for the 3 months incubation period until the eggs hatch. When they are ready to hatch, the hatchlings make a noise while still inside the egg, the parents crack the eggs in their mouths releasing the offsprings and then lead them or carry them to the water in their mouth.
Crocodiles are known to swallow stones when they are on the banks of the water. The crocodile does this to not only help its digestive system but also to aid the crocodile’s water buoyancy. It is thought that by swallowing stones, the crocodile may also be able to swim to deeper parts of the water.
The crocodile is also unable to stick out its tongue. The crocodile is able to grow new teeth very quickly after losing the old ones, throughout the crocodile’s life.
The life span of crocodiles is 40 to 70 years.
