Green sea turtle hatchling

Green sea turtle breeding season begins in late spring and early summer. The males arrive in off-shore waters first and wait for the females to come to the beaches. Adult males are able to breed every year, but females only breed every approximately every 2-4 years once they are sexually mature. The males tend to return to their birth location for the mating process, even if this eans migrating long distances. The females may frequent several breeding grounds, but prefer to lay their eggs at their own nesting beach.
​
Mating can take place either on the surface or under water. Several males will compete for females and may even fight each other, as mating is on a first-come-first serve basis. Females may mate with several males just prior to nesting season and store the sperm for several weeks. When she finally lays her eggs, they will have been fertilized by a variety of males, which may contribute to keeping genetic diversity high within the population.
​
A few weeks after mating, female green sea turtles arrive on the beach and dig holes in the ground for her eggs. Inside the hole, she can lay over 75 - 200 eggs. The eggs are then covered with sand and left to fend for themselves. A female green sea turtle can lay several clusters of eggs before leaving the nesting grounds.
​
After approximately two months, the eggs hatch and the hatchlings make their way to the water. The newly hatched green sea turtles are very susceptible to predators, exposure, and losing their way. Birds, mammals and other predators prey on the young turtles. Light pollution from nearby developments may confuse the young turtles so that they crawl towards the light and not the ocean.
​
For green sea turtle hatchlings that reach the water, it will be at least 10-25 years before they themselves can breed.
