The incubation lasts for 3,5 to 5 months. Hatchling sex depends on the temperature of the developing eggs. Typically, the hatchling will be male if the incubation temperature is below 27,2 degrees Celsius, and female if the temperature is above 31 degrees Celsius. It is a common trait among turtles, crocodiles, and alligators, and is called temperature-dependent sex determination.
