Many turtles from the same beaches show up at the same feeding areas. Once reaching sexual maturity in the Atlantic Oceans, the female Loggerhead makes the long trip back to her natal beach to lay her eggs. The Loggerhead sea turtle in the North Atlantic cover more than 9,000 miles round trip to lay eggs on the North American shore.
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."
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 ]

Common snapping turtles have few predators when older, but eggs are subject to predation by crows, American mink, skunks, foxes, and raccoons. [19] Egg predators use three types of cues to locate turtle nests:
On occasion, on a walk with Loggerhead Marinelife Center, you might even see baby sea turtles hatch from their eggs and scurry to the ocean, which usually emerge in groups of 80 to 120 hatchlings.
The number of eggs in a flatback sea turtle's clutch are fewer than other sea turtles. [6] It will have an average of 50 eggs laid each time in a clutch, while other sea turtles may lay up to 100-150 eggs in a clutch. [6] [8] The eggs are about 55 mm (2.2 in) long within these clutches. [6]
More than 8,000 sea turtle nests were logged across South Carolina beaches in 2022, the second-most ever documented. But threats to habitat and continued development are threats.
