The majority of nesting in the southeast U. Green turtles are an endangered species around the world, but they still nest in increasing numbers on the east coast of Florida. The green sea turtle was listed in the United States under the Endangered Species Act as endangered in While the nesting population may be stable in Suriname, and increasing in Tortuguero, there is insufficient information from other nesting sites to determine a species trend worldwide.
The leatherback is the champion of sea turtles: It grows the largest, dives the deepest, and travels the farthest of all sea turtles. The leatherback was listed in the United States under the Endangered Species Act as endangered in Leatherbacks are seriously declining at all major nesting beaches throughout the Pacific.
In contrast, there has been a recent increase in leatherback nesting on the central and south eastern coast of Florida. It is a solitary nester, and thus, population trends or estimates are difficult to determine.
The decline of nesting populations is accepted by most researchers. The leatherback is the largest sea turtle and can weigh a whopping 2, pounds. Its carapace is somewhat flexible and almost rubbery to the touch. The shells of other sea turtles are made of thick plates called scutes. Sea turtles make incredibly long migrations between feeding and breeding areas. The leatherback travels an average of 3, miles each way.
Sea turtles mate at sea, then come ashore on beaches to lay their eggs. After about 60 days, the eggs hatch and tiny hatchlings make their way from the nest to the water at night, often a deadly ordeal as seabirds, crabs, and other predators prey on the young turtles.
Another threat comes from coastal development. Natural light at the horizon guides the hatchings to the ocean. Lights from hotels, homes, and other buildings can confuse the turtles into heading the wrong way.
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.

When food is not available, they will eat plastic bags, as it resembles a jellyfish. Loggerhead Turtle The loggerhead is most notable for its large head. The body is shaped similar to a heart and can grow up to pounds and 3 feet in length.
