How does a green sea turtle reproduce? A sea turtle lays eggs into a nest dug in the sand.
Once a site is chosen, the turtle uses her hind flippers to dig a vase-shaped hole about two feet deep, and then lays her eggs.
A nesting female will lay multiple nests per nesting season.
How often do green sea turtles lay eggs? The clutches are laid approximately every two weeks, and the period between female nesting season ranges from one to nine years. Temperature determines the sex of the turtle; warmer nests produce female hatchlings and cooler nests produce males.
Where do green turtles lay eggs? A few weeks after mating, a female green sea turtle arrives on the beach and digs a hole in the sand for her eggs. Inside the hole, she lays 75 to 200 eggs and covers the hole with sand.
