The only time Green Sea Turtles emerge from the water, is when they are nesting. When it is time to mate, they migrate over one thousand miles back to their own hatching site. Females are the only ones to emerge; they deposit the eggs- this process takes about 2 hours and usually occurs at night time. They deposit from anywhere between 1 and 7 clutches. Their breeding season has intervals of about 12 days. On average females lay three clutches. That adds up to over a hundred eggs per clutch. Green Sea Turtles return to these nesting sites every two or three years.
