[75] Pollution, both chemical and physical, can also be fatal. Studies on wild D. coriacea discovered individuals may spend as little as 0.1% of the day resting. [46] The most significant Atlantic nesting sites are in Suriname, Guyana, French Guiana in South America, Antigua and Barbuda, and Trinidad and Tobago in the Caribbean, and Gabon in Central Africa. The leatherback turtle is the largest marine turtle and one of the largest living reptiles. Leatherback. On this research project, Dr. Dennis Sammy of Nature Seekers and Dr. Scott Eckert of Wider Caribbean Sea Turtle Conservation Network work alongside a team of volunteers to help prevent the extinction of leatherback sea turtles.[97]. They weigh between 250 and 750 kg (550 and 1650 lb). If the turtle approaches you, maintain a constant speed and allow them to interact on their own terms and leave at will. [44], The leatherback turtle population in the Atlantic Ocean ranges across the entire region. In 1996, a drowned carcass held sarcophagid and calliphorid flies after being picked open by a pair of Coragyps atratus vultures. After days of decomposition, beetles from the families Histeridae and Staphylinidae and anthomyiid flies invaded the corpse, as well. Several Caribbean countries started conservation programs, such as the St. Kitts Sea Turtle Monitoring Network, focused on using ecotourism to highlight the leatherback's plight. Individuals have been recorded diving to depths as great as 1,280 m (4,200 ft). coriacea. Weight: 660 to 1,100 pounds (300 – 500 kg). The leatherback sea turtle is subject to differing conservation laws in various countries. They use both traditional ecological knowledge and Western technology to help manage the turtle populations and protect the turtle's natural environment.[80]. In 1988 on the west coast of Wales, one Leatherback Turtle measured around 2m in size and weighed in at a colossal 900kg! They nest towards the dark and then return to the ocean and the light. Primary threats to the turtles include incidental take in commercial fisheries and marine pollution, as well as the harvest of eggs. With the front arm span around 8 feet (2.5 meters) Weight: Between 1200 pounds (550 kg) and 1450 pounds (664 kg) Habitat: These turtles inhabit the open seas. The eastern Pacific population forages in the Southern Hemisphere, in waters along the western coast of South America, nesting in Mexico, Panama, El Salvador, Nicaragua, and Costa Rica. Leatherbacks, sometimes called the lute turtle or leathery turtle, is the largest turtle on the planet and can grow up to 7 feet long and weigh more than 2,000 pounds. If possible, a maximum depth or body depth, measured after the animal inhales, is also useful. Asian exploitation of turtle nests has been cited as the most significant factor for the species' global population decline. Demonstrating countershading, the turtle's underside is lightly colored. All fl ippers are without claws. Some reports claim "30 years or more",[62] while others state "50 years or more". Hatchlings are attracted to light because the lightest area on a natural beach is the horizon over the ocean, the darkest area is the dunes or forest.

This enormous turtle is the 4 th largest reptile in the world, lighter only than some crocodiles. All turtle species have a bony and sturdy carapace covered with hard scales resembling alligator skin. [19][21] In the Caribbean, the mean size of adults was reported at 384 kg (847 lb) in weight and 1.55 m (5.1 ft) in CCL. Leatherback turtles have a streamline, tear-drop shape that helps reduce drag in the water. It has been listed as an EDGE species by the Zoological Society of London.[84]. Dermochelys coriacea.

Since 1998, the village has been assisting turtles with a hatchery program. However, the Pacific leatherbacks are bigger than the Atlantic leatherback sea turtles. Shaped for speed and built for strength, the Leatherback turtle, Dermochelys coriacea, is a swift behemoth. Size & Weight:4 to 6 feet (130-183 cm). [82], Many human activities indirectly harm Dermochelys populations. Since leatherback sea turtles had been reported to nest only at Espírito Santo's shore, but never in the state of Paraná, this unusual act brought much attention to the area, biologists have been protecting the nests and checking their eggs' temperature, although it might be that none of the eggs are fertile. Habitat. It is also called lute turtle or leathery turtle. The 1992 edition of the Guinness Book of World Records lists the leatherback turtle moving at 35.28 km/h (21.92 mph) in the water.

About nine days pass between nesting events. Nests are raided by humans in places such as Southeast Asia. [35], Leatherback turtles are one of the deepest-diving marine animals. Foraging Ecology and Nutrition of Sea Turtles. Their preferred food is jellyfish, but because they are not very nutritious, each turtle needs to consume enough jellyfish to match its own body weight every day! They are the largest living turtle in the world, growing to more than two meters long and weighing 900 kilograms. Most widely distributed of all sea turtles. Coupled with their countercurrent heat exchangers, insulating fat covering, and large size, leatherbacks are able to maintain high temperature differentials compared to the surrounding water. Leatherback Sea Turtles. The passing of the Endangered Species Act of 1973 ratified its status. Many turtles die from malabsorption and intestinal blockage following the ingestion of balloons and plastic bags which resemble their jellyfish prey. Leatherback Turtle Habitat and Distribution. 55-63 inches. Almost one-quarter (23.5%) of leatherback strandings are due to vessel-strike injuries, which is the highest cause of strandings. This bears importance to humans, as jellyfish diets consist largely of larval fish, the adults of which are commercially fished by humans. Instead, leatherbacks are covered with a firm, rubbery skin. [25] On the other hand, one scientific paper has claimed that the species can weigh up to 1,000 kg (2,200 lb) without providing more verifiable detail. On the Atlantic coast of Costa Rica, the village of Parismina has one such initiative. Figure 1: Leatherback turtle nesting sites . Graphic Credit - NOAA, Jack Javech. Found world wide with the largest north and south range of all the sea turtle species. The leatherback does not have a solid, external bony shell like all of the other sea turtles. It can easily be differentiated from other modern sea turtles by its lack of a bony shell, hence the name. On Florida's Atlantic coast, some beaches with high turtle nesting density have lost thousands of hatchlings due to artificial light. Claws are absent from both pairs of flippers. The leatherback turtle is endangered throughout its global range. During their long migrations, leatherbacks regularly dive to depths greater than 1,000 m (3,281 ft) in search of gelatinous zooplankton to eat. While little research has been done on Dermochelys populations in the Indian Ocean, nesting populations are known from Sri Lanka and the Nicobar Islands. Farther east in French Guiana, nesting is from March to August. 218-220. The Seri people devote ceremonies and fiestas to the turtle when one is caught and then released back into the environment.

In fact, these turtles can reach 6.5 ft (2m) in length and a weight of 2,000 lbs (900 kg). [31], Leatherbacks have been viewed as unique among extant reptiles for their ability to maintain high body temperatures using metabolically generated heat, or endothermy. The leatherback is very different from other sea turtles. One population nests on beaches in Papua, Indonesia, and the Solomon Islands, and forages across the Pacific in the Northern Hemisphere, along the coasts of California, Oregon, and Washington in North America. Organisms from more than a dozen families took part in consuming the carcass. Leatherback turtles have few natural predators once they mature; they are most vulnerable to predation in their early life stages. Funded by the European Regional Development Fund, the Irish Sea Leatherback Turtle Project focuses on research such as tagging and satellite tracking of individuals. [72][73], Leatherback nesting seasons vary by location; it occurs from February to July in Parismina, Costa Rica.
