Do Crocodiles Lay Eggs?

Female crocodiles lay approximately 35 to 50 eggs, with some laying up to 90 eggs at a time, around late June or early July after they have finished building a nest made from vegetation to support and house the eggs. The nests can measure anywhere from 7 to 10 feet in diameter with a height of approximately 2 to 3 feet. The eggs are then incubated in the nest for approximately 90 days with vegetation covering them to protection them and to maintain a certain temperature and environmental conditions.

The sex of the young will be determined by the temperature of the nests. Studies have shown that nests with an internal temperature above 93 degree Fahrenheit tend to result in all males whereas nests with an internal temperature below 83 F tend to result in all females.

Courtship between males and females typically start in April with males emitting loud roars to attract the females. Mating typically happens in early May. The eggs will hatch sometime by the end of August, and the young alligators, which are approximately 6 to 8 inches in length, will make loud pitch noises to encourage the mothers to remove the vegetation from the nests.
