Sea turtles usually lay around 100 eggs at a time, but on average only one of the eggs from the nest will survive to adulthood. [135] Raccoons, foxes, and seabirds may raid nests or hatchlings may be eaten within minutes of hatching as they make their initial run for the ocean. [ 136 ]
It spends most of its life in saltwater and estuarine habitats, with females briefly coming ashore to lay eggs. The loggerhead sea turtle has a low reproductive rate; females lay an average of four egg clutches and then become quiescent, producing no eggs for two to three years. The loggerhead reaches sexual maturity within 17–33 years and ...
About 50% of female sea turtles complete "false crawls," which occur when they crawl onto the beach but return to the water without laying eggs.

Most sea turtles lay their eggs at night, but a Palm Beach woman was in the right place at the right time, saw a leatherback turtle do it during the day. "Like winning the lottery."
In sea turtles, hatchling sex is determined by incubation temperature. [8] In species in which eggs are laid then buried in sand, indentations in the sand can be a clue to imminent hatching. [9] In sea turtles, this usually occurs about 60 days after the laying of eggs, and often at night. [10]
Sea turtles nest in a specific area, such as a beach, leaving the eggs to hatch unattended. The young turtles leave that area, migrating long distances in the years or decades in which they grow to maturity, and then return seemingly to the same area every few years to mate and lay eggs, though the precision varies between species and populations.
