All species of sea turtles are threatened or endangered and protected through Florida Statues, Chapter 370, and by the United States Endangered Species Act of 1973. The only time leatherbacks come ashore is to lay their eggs, which they do only on sandy, undisturbed beaches. They face threats on both nesting beaches and in the marine environment. A nest of 100 eggs will probably produce no more than one or two adults. It is a federally and state-listed endangered species. Leatherbacks nest in the tropics but range widely in the world’s oceans, moving into colder, higher latitude waters during summer months. This population of sea turtles has declined by more than 98% since 1990. Climate change is expected to significantly disrupt the marine and terrestrial environments on which they depend. Current estimates put the worldwide female population at about 100,000. Leatherback sea turtles are an endangered species in the United States, making the poaching illegal with substantial penalties. Because leatherback sea turtles are a protected species, it is illegal to kill, harm, collect, harass or sell them. Graphic Credit - NOAA, Jack Javech. Leatherbacks nest in the tropics but range widely in the world’s oceans, moving into colder, higher latitude waters during summer months. Leatherback Sea Turtle Latin name: Dermochelys Coriacea, Conservsation status: vulnerable (population is decreasing) The largest of all sea turtles, the Leatherback has been on Earth since the dinosaurs—100 million years. Leatherbacks nest on tropical beaches and are found in all the world’s oceans except the Arctic and Antarctic. Sea Turtles and Sea Turtle Nests! They are the largest of the turtle species living in the sea, growing up to 7 feet long. Leatherback Sea Turtle Fact Sheet – p. 2 A Species of Greatest Conservation Need in the Massachusetts State Wildlife Action Plan Please allow the Natural Heritage & Endangered Species Program to continue to conserve the biodiversity of Massachusetts with a contribution for FAMILY: Dermochelyidae STATUS: Endangered throughout its range (Federal Register, June 2, 1970). They are also the only sea turtle with a soft, rubbery shell. Worldwide, hundreds of thousands of sea turtles a year are accidentally caught in shrimp trawl nets, on longline hooks and in fishing gillnets. Other effects of climate change include increased numbers of hurricanes and severe storms, associated beach erosion, nest loss and the destruction of nesting habitat. Lights can also mislead hatchling leatherbacks when they begin their frantic rush across the beach to the surf. Contact a park ranger to report a person disturbing a sea turtle nest or an injured, dead, or harassed sea turtle. They face threats on both nesting beaches and in the marine environment. This gives scientists a chance to count and tag them. It has been estimated that 11,000 marine turtles are caught in nets every year. The sex of a developing leatherback embryo is dependent on the temperature of incubation in the nest, with warmer temperatures producing females and cooler temperatures producing males. In the southeastern U.S., coastal communities are encouraged to turn off exterior lights during the hatching period so the hatchlings can find their way home. They are strong and graceful swimmers, with powerful front flippers.

Leatherbacks have special adaptations that allow them to eliminate waste gases through their skin, so they can stay under water for extraordinarily long periods. Before any conclusions are reached, additional research is required. Turtle Island Restoration Network and the Center for Biological Diversity recently submitted a letter to NMFS opposing downlisting the NW Atlantic leatherback turtle from “endangered” to “threatened” under the Endangered Species Act. Inside their bodies, they actually convert salt water to fresh water, ingesting the sea water around them and excreting the salt. 10 Things You Can Do to Save Endangered Species, Support our work with a one time or recurring gift. Up to 5 feet (1.5 m) Threatened or Endangered Mainly overharvesting of sea turtles for meat, eggs, leather, and tortoise shells up until the 1970s caused turtle populations to crash. After leatherback females lay their eggs, they immediately return to the sea. Leatherbacks are the largest sea turtles. Join the Endangered Species Coalition Activist Network to receive emails with actions that you can take to protect endangered and threatened species. WWFs work on sea turtles focuses on five of those species: green, hawksbill, loggerhead, leatherback and olive ridley. Loss of these coastal nesting habitats is one of the primary threats to leatherback survival. Another beach in Malaysia is the site of a creative “managed exploitation” effort aimed at saving the species whi… Leatherback sea turtles were federally listed as endangered throughout their range on June 2, 1970. Global climate change threatens reproduction on nesting beaches throughout the leatherback’s range. American Museum of Natural History They have survived for more than a hundred million years, but is now facing extinction. Their bodies are insulated by a thick layer of fat -- another adaptation that is unique among turtles to leatherbacks. This important nesting population is the third largest in the world. Weight: 800 pounds (365 kg) average, POPULATION:100,000 females worldwide, males unknown, CURRENT RANGE":Atlantic, Indian, and Pacific Oceans, CONSERVATION: Use of Turtle Excluder Devices and protection of critical nesting habitats; CITES trade restrictions. Leatherback sea turtles are federally listed as endangered. Interesting Facts: The leatherback is the most ancient species of living sea turtle, as well as the largest and heaviest turtle in the world. Read more about health and safety. Endangered: Leatherback Sea Turtle main content. A massive 800-pound endangered leatherback sea turtle delighted visitors at a Florida beach ahead of Memorial Day weekend when they saw it nesting near the waterfront. Climate change is expected to significantly disrupt the marine and terrestrial environments on which they depend. Leatherbacks (and all six other species of marine turtles) will be affected by freshwater from melting glaciers, changes in salinity and oxygen, and altered ocean chemistry as shifts occur in currents, key habitats, and the range and abundance of prey species. Avoiding plastics is becoming just as difficult for marine life as it is for us! While all other sea turtles have hard, bony shells, the inky-blue carapace of the leatherback is somewhat flexible and almost rubbery to the touch. These front flippers are significantly larger than the back flippers. In Danger of Extinction: Leatherback Sea Turtles are endangered due to habitat loss, wildlife trade, collection of eggs, by catch, pollution, climate change, and humans poaching (killing) the turtles for their valuable soft shell. They migrate over long distances, which makes them hard to track and even harder to count. Climate change is altering the oceans physically and chemically as warmer waters expand, ice covers recede, circulation patterns change, and the pH of the oceans declines. NOAA Fisheries has made it a priority to focus recovery efforts on stabilizing and recovering Pacific leat… Any leatherback that survives to adulthood has overcome enormous odds. Unlike other species of sea turtles, which have hard shells, the leatherback's shell is leathery; it feels almost rubbery. Threats Leatherbacks are facing extinction mainly due to human impacts on their environment. In the marine environment, plastic pollution is a growing global problem. Efforts to protect these species need to focus on the nesting beaches. The leatherback sea turtle is classified as a nongame species. The adult leatherback can reach 4 to 8 feet in length and 500 to 2000 pounds in weight. The most important reason is that it makes the specimen whole. Directions, ticket info, and visitor tips. Many of them are leatherbacks. Nesting sites are disturbed through tourism or commercial development, and poachers often harvest eggs for food. For example, the extremely endangered Malaysian leatherback sea turtles are still heavily exploited by local peoples. The passing of the Endangered Species Act of 1973 ratified its status. Threats Coastal habitat loss, commercial fishing (caught in drift nets), egg poaching, SIZE: Sea turtles need to reach the surface to breathe, and therefore many drown once caught. Their primary food is jellyfish. But because they are so difficult to count, it's impossible to determine how leather-back populations are affected by loss of nesting sites, plastic ingestion, egg poaching, and commercial fisheries. An adult leatherback sea turtle is generally longer than an average-size man is tall. In the last 17 years, leatherbacks have expanded their range in the North Atlantic by about 250 miles. In the past three generations, the population of Pacific leatherback sea turtles has dramatically plummeted by 83 percent according to the IUCN Red List. Leatherbacks have been on the Endangered Species List since 1970. New York, NY 10024-5102Phone: 212-769-5100. Seven different species of sea (or marine) turtles grace our ocean waters, from the shallow seagrass beds of the Indian Ocean, to the colorful reefs of the Coral Triangle, and even the sandy beaches of the Eastern Pacific. Pacific leatherbacks are one of eight Species in the Spotlight. They are found in oceans and seas around the world, in habitats ranging from tropical to subarctic. So, Why is the head such a big deal? And then there's the plastics problem. Leather-backs eat twice their weight each day. In recent studies, nearly half of all leatherbacks examined had plastic or cellophane in their stomachs. The greatest of these threats worldwide are incidental capture in fishing gear and harvest of leatherback eggs and adults. All leatherback turtle populations are listed as endangered under the Endangered Species Act. According to NOAA, the leatherback populations in the Atlantic and Caribbean are somewhat stable, however, Pacific populations are in a somewhat dire position, with Western Pacific populations declining 80 percent in recent decades and Eastern Pacific populations declining nearly 97 percent. The Leatherback Project exists to combat the environmental crisis with a specific focus on leatherback conservation and ocean health Will you join us in protecting this ancient reptile? Designation: The leatherback turtle was listed under the Endangered Species Act as endangered in 1970. Leatherbacks are among the most wide-ranging of all vertebrates. Females may lay more than 100 eggs in a nest, but many of these are eaten by predators (including humans) before they hatch. Leatherback sea turtles are the biggest turtles on Earth. For educational purposes the head can illustrate the general form of this specialized jellyfish eater. Males can reach up to 8.5 ft (2.6m) and 2000 lbs (900 kg). Changing marine temperatures are expected to continue to alter the range of leatherbacks. Length:  Reserve your timed-entry tickets. The Pacific leatherback populations are most at-risk for extinction. On one nesting beach, 1500 leatherbacks were counted in the 1950s, yet by the early 1990s fewer than 50 came ashore. Leatherbacks have been on the Endangered Species List since 1970. The leatherback sea turtle, unlike other sea turtles… It's not known how much plastic it takes to kill a leatherback, but two facts are clear: no animal can digest plastic, and the amount of plastic in the oceans is increasing drastically every day. Threats related to Global Warming The endangered Western Pacific leatherback sea turtles that visit California, Oregon and Washington’s coastal waters could gain long overdue habitat protections to prevent their extinction under a new government proposal. Before any conclusions are reached, additional research is required. Changing ocean conditions are especially threatening in the Pacific where leatherback nesting populations are declining dramatically. In my work with leatherback sea turtles, I’ve been up close and personal with the impacts of plastic on this endangered species. The leatherback's proportions and streamlined shape are advantageous for long distance swimming. Fishing is another. It can grow over six feet long, weigh up to one ton, and dive over 3,000 feet—deeper than any other turtle. Unfortunately, they can't distinguish between jellyfish and clear plastic debris, such as sandwich bags. The moon's reflection on the water may help them find their way but artificial lights disorient them and can cause them to crawl the wrong way and die of exhaustion and dehydration. Only the females come ashore and then for just a couple of hours while they lay their eggs. The leatherback sea turtle is subject to differing conservation laws in various countries. Sea turtles are large, aquatic reptiles with forelimbs specially modified for swimming. Unlike other sea turtles, leatherbacks have a flexible, rubbery carapace that allows them to dive deeper than 4100 feet (1250 meters). The Leatherback sea turtles are mainly endangered because of artificial lights, pollution, hunting and fishing, egg harvesting, habitat loss, predators, debris, water crafts, and food loss. The United States listed it as an endangered species on 2 June 1970. The leatherback sea turtle also is a Species of Greatest Conservation Need in the N.C. Wildlife Action Plan. They are also called Lute turtles. “All leatherback turtle populations are listed as endangered under the Endangered Species Act. DESCRIPTION: The leatherback is the largest, deepest diving, and most migratory and wide ranging of all sea turtles. Since males don't come ashore at all, it's virtually impossible to estimate their numbers. Known as bycatch, this is a serious threat to leatherback turtles. The shell is black, often speckled with white or yellow spots. Of the hatchlings that do make it out of the nest, the vast majority are eaten by predators (primarily gulls and other birds) on the beach or in the ocean. Eastern Pacific leatherback turtles are critically endangered. Leatherbacks build their nests on remote stretches of sandy beach. (All others have hard, bony-plated shells.) Turtle Excluder Devices, called TEDs, have been built into some nets that let captured animals escape, but shrimpers complain that TEDs cut down on their catch size. It’s too soon to move the subpopulation of these sea turtles from endangered to threatened. Leatherbacks get caught in commercial shrimp nets and suffocate. Turtles are frequently observed off Stonington and in Block Island Sound during the summer months. Their biggest threats are the result of human activity. Much of this population decrease can be traced back to an increase in intense egg collection and fisheries bycatch. Warmer-than-usual waters of El Nino years significantly reduce oceanic productivity by inhibiting the mixing of surface water with deeper, cold waters, resulting in less available food near the surface and reducing the reproductive potential of leatherbacks and other marine species. Clutches of eggs are often illegally poached, and the offspring that do hatch sometimes become attracted to beach resort lighting, so they crawl away from the sea instead of toward it. Excerpted from the 1996 exhibition Endangered! Warmer beaches initially will produce more female offspring, to the detriment of the production of males; hot beaches ultimately will be lethal to embryos. Leatherback turtles are the most numerous sea turtle species nesting in Trinidad in Tobago. The leatherback turtle is one of the most critically endangered species in the world and is on the IUCN red list. We are working to reverse this trend by tackling the 5 most deadly threats to leatherbacks and other sea turtles around the world. A Singular Sea Turtle... More than six feet long, weighing as much as 1400 pounds (636 kg), leatherbacks are the world's largest pelagic (ocean-going) turtles. Sea turtles are only nominally protected by law in most countries where nesting occurs. Leatherbacks come from as far as Africa, Canada and the UK to nest on our beaches. All sea turtle species are … The Endangered Species Coalition’s mission is to stop the human-caused extinction of our nation’s at-risk species, to protect and restore their habitats, and to guide these fragile populations along the road to recovery. But because they are so difficult to count, it's impossible to determine how leather-back populations are affected by loss of nesting sites, plastic ingestion, egg poaching, and commercial fisheries. Leatherback eggs are harvested in Malaysia for food, and in some parts of Asia, the turtle is hunted for its oil and flesh. Seasonal variation in rainfall and drought will alter incubation conditions and increase embryo losses. The Pacific population of leatherback sea turtles has suffered most over the last twenty years: as few as 2,300 adult females now remain, making the Pacific leatherback the … Out of the 7 subpopulations of the leatherback sea turtle, 4 are critically endangered, 1 is endangered and 2 are data deficient. They spend almost all of their lives at sea, swimming into shallow bays and estuaries to court and mate. 200 Central Park West Their shell is composed of two pieces, the top, or carapace, and the bottom, or plastron. Turtle Island Restoration Network nominated the Pacific leatherback sea turtle for the report due to the rapid decline in their population.
