Gender of the baby croc depends on the nest temperature. Crocodilians have a "preferred" body temperature of around 30-33C, and to achieve such temperatures they move back and forth between warm and cool parts of their environment. Despite fluctuating external conditions, the temperature in the egg chamber stays relatively stable, with the preferred temperature being around 31-32°C.
