where do loggerhead sea turtles lay their eggs
Loggerhead sea turtle All sea turtles have similar basic nesting behaviors. Females return to lay eggs at intervals of 12â€“17 days during the nesting season, on or near the beach where they hatched.[60][61] They exit the water, climb the beach, and scrape away the surface sand to form a body pit. With their hind limbs, they excavate an egg chamber in which the eggs are deposited. The females then cover the egg chamber and body pit with sand, and finally return to the sea.[66] This process takes one to two hours, and occurs in open sand areas or on top of sand dunes, preferably near dune grasses that the females can use to camouflage the nest.[61] The nesting area must be selected carefully because it affects characteristics such as fitness, emergence ratio, and vulnerability to nest predators.[49] Loggerheads have an average clutch size of 112.4 eggs.[67]
Olive ridley sea turtle The olive ridley turtle has a circumtropical distribution, living in tropical and warm waters of the Pacific and Indian Oceans from India, Arabia, Japan, and Micronesia south to southern Africa, Australia, and New Zealand. In the Atlantic Ocean, it has been observed off the western coast of Africa and the coasts of northern Brazil, Suriname, Guyana, French Guiana, and Venezuela. Additionally, the olive ridley has been recorded in the Caribbean Sea as far north as Puerto Rico. A female individual was found alive on an Irish Sea beach on the Isle of Anglesey, British Isles in November 2016, giving this species its northernmost appearance. It was taken in by the nearby Anglesey Sea Zoo while its health was being assessed.[11] The olive ridley is also found in the eastern Pacific Ocean from the Galapagos Islands and Chile north to the Gulf of California, and along the Pacific coast to at least Oregon Migratory movements have been studied less intensely in olive ridleys than other species of marine turtles, but they are believed to use the coastal waters of over 80 countries.[12] Historically, this species has been widely regarded as the most abundant sea turtle in the world.[6] More than one million olive ridleys were commercially harvested off the coasts of Mexico in 1968 alone.[13]
