Green Sea Turtle
1. Baby sea turtles are either 'cool daddies' or 'hot mamas'.
The temperature of the sand surrounding the eggs in a sea turtle nest is a determining factor in the sex of the hatchings. Lower temperatures produce more males, higher temperatures produce more females. This phenomenon, called Temperature-Dependent Sex Determination or TSD, is true of other reptiles, such as alligators and crocodiles.
When they are ready to hatch, the hatchlings dig out of their sandy nest and scurry to enter the ocean before they are eaten by hungry birds and crabs.
