Crocodile mothers exhibit some of the most sophisticated parental care among reptiles, actively protecting their offspring from the time the eggs are laid until the young are capable of surviving independently.1

Protecting the Eggs

After laying their eggs in either a hole in the ground or a mound of vegetation and soil, female crocodiles remain nearby to guard the nest against predators. This vigilance lasts throughout the entire incubation period, which typically spans several months.213

Assisting and Protecting Hatchlings

When the eggs are ready to hatch, the young produce chirping and squeaking sounds from within their shells. This vocalization signals the mother to return to the nest. She then performs the following actions:21
* Excavation: She removes the soil or debris covering the eggs to allow the hatchlings to emerge.21
* Assistance: She may use her tongue to carefully open the eggshells and help the young hatch.21
* Transportation: She often carries the hatchlings to the water in her mouth.21
* Ongoing Care: The mother remains close to her offspring, providing protection from predators for several weeks to months until they are large enough to disperse.231
