The incubation period for crocodile eggs typically ranges from 55 to 100 days.1

During this time, the temperature of the nest is crucial, as it not only aids the development of the embryo but also determines the sex of the offspring. Once the young are fully developed after two or three months, they may signal their readiness to emerge by uttering squeaks from within the egg. The female parent often assists in the hatching process by carefully opening the eggs and transporting the hatchlings to the water.1
