Leatherback turtle hatchlings The world's largest sea turtle, the leatherback, previously listed as “vulnerable” has been classified as endangered due to the threats posed by overfishing and the unsustainable harvesting of its eggs and meat. The leatherback turtle averages about 1.6 meters (5.2 feet) in length and weighs between 250 and 700 kilograms (550 and 1,540 pounds), is found in tropical and temperate waters around Australia. __
