They eat foods such as shrimp, sea sponges, snails, algae, moluscs, sea weed, and crabs. • It is unknown what their population is because male sea turtles and young juvinile sea turtles do not go back to the shore once they hatch and they remain at sea. • Sea turtles such as green sea turtles have the ability to stay underwater for up to five hours. This is despite their actual feeding time being less than five minutes. • When they are underwater, the sea turtle slows their heart rate in order to preserve their oxygen underwater. This can slow up to 9 minutes per beat. • They enjoy warm and temperate waters and they migrate long distances as far as 1400 miles between the areas they feed and where they nest. • Not much is known about the behaviour of sea turtles as they spend most of their time at sea and much of the information gathered has been obtained from observing females and their hatchlings. • When they nest females will dig out a nest in the ground an bury their eggs before they return to the sea and leave the eggs alone. • When they hatch, the young sea turtles are completely on their own and without the aid of their mother. They will take as long as a week to dig themselves out of the nest in which they are buried. • Once they have dug themselves out of the burrow, young sea turtles will start to move towards the ocean but will do this in the cover of night to avoid predators and launch out to the sea left to fend for themselves.
