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.
Various species of sea turtles bury their eggs on beaches under a layer of sand that provides both protection from predators and a constant temperature for the nest. Snakes may lay eggs in communal burrows, where a large number of adults combine to keep the eggs warm. Some species coil their torsos around the eggs to provide heat for incubation.
A sea turtle clutch. A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in double-clutching. The technique is used to double ...
In Mexico, turtle eggs are a common meal; locals claim the egg is an aphrodisiac. [87] Eating turtle eggs or meat can cause serious illness due to harmful bacteria, such as Pseudomonas aeruginosa and Serratia marcescens, and high levels of toxic metals that build up through bioaccumulation.

While most species build nests and lay eggs where they forage, some travel miles. The common snapping turtle walks 5 km (3 mi) on land, while sea turtles travel even further; the leatherback swims some 12,000 km (7,500 mi) to its nesting beaches. [13] [89] Most turtles create a nest for their eggs. Females usually dig a flask-like chamber in ...
The chemicals in the plastic that sea life eats damages their internal organs and can also clog their airway. The chemicals in the plastic that they eat is also a leading cause of the death of the turtles. If the turtles are close to laying eggs, the chemicals that they ingested from the plastic can seep into their eggs and affect their offspring.
Sea Turtle laying eggs at designated natal beach Geomagnetic imprinting is done by the use of inclination angle and field intensity to imprint onto the magnetic fields of the sea turtles natal homes. Imprinting is an innate learning process that is inherited within species to recognize important landmarks and resources.
Mating takes place yearly, in early spring in the southern part of its geographic range, and in later spring in the northern part. About two months later, the female builds a nest and lays a clutch of 10–50 eggs. [17] It was found that some females lay eggs every year and some females lay eggs every other year. [30]
