More than 90% of hatchlings are eaten by predators. Loggerhead turtles are well known for their big heads and extremely powerful jaws, therefore they are equipped to consume hard-shelled prey such as horseshoe crab (Duermit, 2007).

The leatherback has been tracked crossing the entire Pacific Ocean from Asia to the US West coast to forage on swarms of jellyfish off the coasts. Sea turtles face development on their natural nesting beaches, which means they have to contend with such things as artificial light, and loss of habitat and nesting sites due to construction and beach erosion.

This turtle predator is famously known for its trick where it attacks on the sea turtles from underneath. The prey of this turtle is: coral, seaweed, kelp, small fish, and plants on the reef.

Leatherbacks have sharp, pointed cusps on their jaws which enable them to pierce and hold onto jellyfish. Our award-winning programs help save sea turtle hatchlings on important nesting beaches around the world, work with the tourism industry to end the turtleshell trade, and educate students and travelers about how to help save sea turtles. The seagrass Thalassia testudinum is commonly known as "turtle grass" because in some areas like the Caribbean, green sea turtles eat it almost exclusively.
