Wild Sea Turtle Leatherback Nesting

Leatherback sea turtles undertake remarkable nesting journeys to tropical beaches, where their nests face threats from beach erosion, predation, and illegal collection.

Key Facts

Leatherbacks are the largest reptiles on Earth and have the longest migrations of any sea turtle
Female leatherbacks return to beaches near their birth site every 2-5 years to nest
A single female may lay 6-12 clutches of approximately 80 eggs per season
Natural hatch success is 60-80% but human disturbance can dramatically reduce this
Trinidad hosts the world's most important leatherback nesting beaches
Egg poaching in some regions removes entire clutches from unprotected beaches
Beach development compresses nesting area and increases false lighting disorienting hatchlings
Climate change is causing sand temperature increases that affect sex ratios of hatchlings

Welfare Considerations

Female leatherbacks emerging to nest are physiologically committed to the process - disruption causes extreme stress and nest abandonment that wastes enormous reproductive investment. The nesting process itself is exhausting, taking 1-2 hours of intense physical effort. Hatchlings that emerge from nests on overdeveloped beaches navigate by the brightest direction - artificial lights pull them inland where they die from dehydration or vehicle strikes. Each clutch represents significant maternal investment; protection of nesting beaches is direct welfare protection for thousands of individual animals.
