About
I am the largest sea turtle in the world! I can grow up to seven feet and weigh more than 2,000 pounds. While all other sea turtles have a hard body shell, I do not. You can recognize me by my soft carapace (top shell).
Did You Know?
I can dive to depths of 4,200 feet, deeper than any other turtle, and I can hold my breath for up to 85 minutes.
Status and Conservation
I spend my days swimming through the vast open ocean looking for tasty treats. Unfortunately, I encounter a lot of trash and other dangers along my journey. I have large front flippers that can easily get entangled in trash or lost fishing gear, which makes it hard for me to swim and can even be fatal.

In the Bird's Head Seascape of the Coral Triangle, we work to protect the nesting area of the largest remaining population of leatherback turtles in the Pacific Ocean. WWF also supports the patrolling of leatherback turtle nest beaches and helps equip local turtle conservationists. These conservation efforts often lead to ecotourism opportunities and offer alternative livelihoods for local communities.

Satellite telemetry allows researchers to track marine turtles as they swim from place to place. These satellite tags do not harm the turtles in any way and are designed to eventually fall off.

More than 20 leatherbacks have been fitted with transmitters to analyze their migratory routes in the Atlantic Ocean and hopefully reduce bycatch mortalities.
