An ancient mariner of our oceans, with a lineage dating back 100 million years, tracing its origins to the era when dinosaurs roamed the earth. Despite surviving natural cataclysms that extinguished many other species, today’s Leatherbacks face threats that have caused their numbers to decline precipitously in modern times.
Leatherbacks are truly unique among sea turtles. Instead of a hard shell like other species, they have a distinctive flexible carapace that is covered in leathery skin, hence their name. This specialized shell is composed of a matrix of bony plates beneath the skin, allowing for a more hydrodynamic shape that aids in deep diving and long-distance swimming. Their adaptability in thermal regulation, a rare trait for reptiles, allows them to maintain a core body temperature that can function effectively in a wide range of water temperatures. This is partly why they can be found in all oceans, from the tropics to the subpolar regions.
Renowned for their epic migratory journeys, Leatherbacks traverse thousands of miles between their nesting beaches in tropical regions and their feeding grounds, which can be located in temperate and even subpolar latitudes. This extensive travel is driven by their need to consume vast quantities of jellyfish, which form the bulk of their diet and are more abundant in cooler waters.
The global distribution of Leatherbacks is categorized into seven Regional Management Units (RMUs), which are essentially subpopulations that are geographically and sometimes genetically distinct. Each RMU faces its own set of challenges, but there are common threats that imperil Leatherbacks across the globe.

- Their deepest dive ever recorded, reaching over 1.2 km( 4,000 ft) was deeper than other marine mammals.
- The leatherback turtle can grow up to 2 m (7 ft) long and weigh more than 2,000 pounds; it is the biggest turtle on Earth.
- The carapace’s seven ridges contribute to its more hydrodynamic structure.
- They use a special set of adaptations to create and retain body heat to maintain warm body temperatures in chilly water.
- Warming temperatures and climate change threaten the leatherback population’s long-term reproductive success.
- The decaying ocean plastic that resembles their primary prey, such as jellyfish, salps, and siphonophores, is ingested by leatherbacks, posing a serious threat to their survival.
