Sea turtles can rest or sleep underwater for several hours at a time but submergence time is much shorter while diving for food or to escape predators. A female loggerhead tracked at sea made up to 500 dives every 12 hours. During routine activity green and loggerhead turtles dive for about 4 to 5 minutes and surface to breathe for 1 to 3 seconds. The blood of sea turtles can deliver oxygen efficiently to body tissues even at the pressures encountered during diving. The lungs are adapted to permit a rapid exchange of oxygen and to prevent gasses from being trapped during deep dives. There is currently limited population data. Flatback turtles are found only in Australia and are not known to. With a single explosive exhalation and rapid inhalation, sea turtles can quickly replace the air in their lungs. Flatback sea turtles nest only on Australian beaches and have the shortest migratory range of all sea turtles. They are unique as the only sea turtle species not to have an oceanic phase as hatchlings. Sea turtles spend almost all their lives submerged but must breathe air for the oxygen needed to meet the demands of vigorous activity.

These long-distance travelers have been known to swim up to 4,828 km.Īlthough sea turtles cannot withdraw their heads into their shells, the adults are protected from predators by their shells, large size, and thick scaly skin on their heads and necks. Their smooth shells and paddlelike flippers help them speed through the water as fast as 24 kph. Sea turtles are some of the largest and most endangered turtles in the world and live in almost every ocean of the world.
