The leatherback is the largest living turtle and lacks a hard shell; its back is covered by flexible dark skin with seven longitudinal ridges. Powerful front flippers carry it across entire ocean basins, including cold waters. It dives deeply for jellyfish and other soft-bodied prey, while females return to tropical sandy beaches to nest (Wikipedia, general species account). It is Nationally Critically Endangered (Thailand Red Data 2025).
