How many times a year do sea turtles lay eggs?
Recent studies suggest that some females of some species will visit more than one nesting beach (other than the original beach) in a season. Females usually lay between 1 and 9 clutches of eggs per season. Females may nest every 2 or 3 years. Female green turtles may lay 1,900 to 2,300 eggs within a lifetime.
How many times do turtles breed a year?
In most species, eggs are laid annually; a few species lay every other year, and some lay twice in one nesting season. The sea turtles generally nest in three- to four-year cycles, the female usually laying multiple clutches of eggs during each nesting season.

What is the lifespan of a sea turtle?
What we do know is that sea turtles live a long time (some can live up to 50 years or more) and have similar lifespans to humans. Most marine turtles take decades to mature—between 20 and 30 years—and remain actively reproductive for another 10 years.

And, it takes the newborns about 20 years to be matured and grown up. If you look on the previous page, it will show you a exponential growth graph of the species.
How many eggs does a green sea turtle lay?
Inside the hole, she lays 75 to 200 eggs and covers the hole with sand. At this point, her role is complete, and she leaves her eggs to fend for themselves. A female green sea turtle can lay several clutches of eggs before she leaves the nesting grounds. After about two months, the eggs hatch and the hatchlings make their way to the water.
When does the life cycle of a sea turtle start?
The sea turtle life cycle starts when a female lays its eggs on a nesting beach, usually in the tropics. From six weeks to two months later (depending on the species), a tiny hatchling makes its way to the surface of the sand and heads to the water, dodging every predator imaginable.
When do green sea turtles come to the beach?
The breeding season occurs in late spring and early summer. The males arrive in offshore waters first and wait for the females to come to the beaches. Adult males can breed every year, but females only breed every three to four years. A few weeks after mating, a female green sea turtle arrives on the beach and digs a hole in the sand for her eggs.
