Climate change affects the turtles by warming the temperature of the sand that sea turtle eggs are laid in, which in turn affects the outcome of the hatchlings’ sex. Leatherbacks are obligate jellyfish feeders, and while in Canadian waters are found to feed almost exclusively on large scyphozoan jellyfish (such as lions. Six of the seven sea turtle species are classified as threatened, endangered, or critically endangered, due largely to human impact in the form of hunting, bycatch in fishing nets, pollution, and climate change. Lights from hotels, homes, and other buildings can confuse the turtles into heading the wrong way. Natural light at the horizon guides the hatchings to the ocean. Another threat comes from coastal development. There are populations with different colorings and markings in the Atlantic, Indian, and Pacific Oceans. Six of the seven species of sea turtles that swim the planet’s waters leatherback, loggerhead, Kemp’s ridley, green, olive ridley, and hawksbill are found in every ocean except the Arctic and.

Range Green sea turtles are found around the world in warm subtropical and tropical ocean waters, and nesting occurs in over 80 countries. In both areas, most species are aquatic, living in bodies of water ranging from small ponds and bogs to large lakes and rivers. Sea turtles mate at sea, then come ashore on beaches to lay their eggs. Habitats common map turtle box turtle Turtles have adapted to a remarkable variety of environments, but the greatest number of species occur in southeastern North America and South Asia.

Sea turtles make incredibly long migrations between feeding and breeding areas.
