The Leatherback Sea Turtle (Dermochelys coriacea) is the largest of all living turtles, reaching lengths of up to 2 meters and weighing over 600 kilograms. Unlike other sea turtles, it lacks a hard bony shell; instead, its carapace is covered by a thick, leathery skin with embedded small bones that form seven distinct ridges running along its length. The body is hydrodynamic and streamlined, adapted for long-distance swimming across oceans. Its coloration is generally dark gray or black with white or pale spots. Leatherbacks are specialized feeders, primarily consuming jellyfish and other soft-bodied invertebrates, helping to maintain marine ecosystem balance.
Aggressive or Danger to Human? This species is not aggressive and poses no danger to humans. It is a gentle species and will avoid confrontation if approached.
Population Status: Vulnerable (VU) Globally (Source: IUCN Red List).
Habitat and Habits: Leatherback Sea Turtles are highly migratory, capable of crossing entire ocean basins between feeding and nesting sites. They inhabit both tropical and temperate waters, often venturing into colder regions due to their unique ability to regulate body temperature. Nesting typically occurs on sandy tropical beaches, with females returning to the same area where they were born to lay eggs. After hatching, juveniles spend years in the open ocean, feeding on jellyfish, salps, and other gelatinous prey. Major nesting areas are found in the Caribbean, Southeast Asia, and the Pacific. Despite their wide range, populations are declining due to egg harvesting, fishing bycatch, marine pollution, and habitat loss.
