English: It takes several decades for adult sea turtles to reach sexual maturity. The mature turtles migrate, sometimes for thousands of miles, to reach breeding sites. Male and female turtles mate in the water, and the males return to deep sea to feed. For several weeks, female sea turtles alternate between mating in the water and laying their eggs on land. Before laying her eggs, a female turtle will dig a hole in the sand with her hind flippers. She covers it with sand and returns to the ocean. About two months pass for the eggs to incubate under the sand. Afterwards, the eggs hatch, generally at night to avoid predation, and the hatchlings crawl to the water. They then swim out to sea to begin their own cycle of maturing and reproducing. Sea turtles can continue this cycle until they are 80 years old.
