Sea Turtles (super family Chelonioidea) occupy all the world oceans apart from the Arctic. Sea turtles are roughly always flooded but breathe air. With a single volatile smell and rapid inhalation, sea turtles can quickly refill their lungs when they surface. Their lungs have adapted to consent quick exchange of oxygen and to avoid trapping gasses through deep dives. Throughout their tradition green and loggerhead sea turtles dive for about 4 to 5 minutes and surface to breathe for 1 to 3 seconds.
Loggerhead sea turtles have been known to often plane for a longer period of time. Sea turtles can rest or sleep underwater for some hours at a time but submergence time is much shorter while hunting or to flee predators. Activity and stress influence breath holding aptitude, which is why sea turtles drown in shrimp trawls and other fishing equipment within a relatively short time. Sea turtles must emerge while breeding, given the extra level of movement. The natural life of sea turtles has been speculated at 80 years.
After about 3 years of growing, adult female sea turtles return to land to nest at night. Different species of sea turtles display various levels of philopatry. In the excessive case, females depart to the beach where they hatched. This can take position every two to four years in adulthood. Sea turtles create from one to eight nests per season.
The adult nesting female sea turtles drag her onto the beach and finds appropriate sand on which to make a nest. Using her hind flippers, she digs a round hole 40 to 50 centimeters (16 to 20 in) deep. After the hole is dug, the female sea turtles then starts filling the nest with a grasp of soft shelled eggs one by one until she has deposited around 50 to 200 eggs, depending on the classes. Several species have been reported to lay 250 eggs like hawksbill.
