Sea Turtle

Cheloniidae and Dermochelyidae

Sea turtles are remarkable marine reptiles that have been navigating the world's oceans for over 100 million years. They are easily recognized by their large, streamlined shells and flippers adapted for swimming. There are seven species of sea turtles, including the green, loggerhead, Kemp's ridley, olive ridley, hawksbill, flatback, and leatherback turtles. These species vary in size, with the leatherback being the largest, reaching up to 2 meters in length and weighing as much as 700 kilograms. Sea turtles are known for their long migrations, often traveling thousands of kilometers between feeding grounds and nesting sites. They exhibit fascinating behaviors, such as synchronized nesting known as arribadas, where thousands of females come ashore to lay eggs simultaneously. Sea turtles play a crucial role in marine ecosystems, such as maintaining healthy seagrass beds and coral reefs. Unfortunately, they face numerous threats, including habitat loss, pollution, climate change, and bycatch in fishing gear. Conservation efforts are vital to ensure their survival, as they are key indicators of ocean health.

Fun Facts

Sea turtles have been swimming in our oceans for over 100 million years, even outliving the dinosaurs!
A sea turtle's gender is determined by the temperature of the sand where the eggs are incubated—warmer sand produces females, while cooler sand produces males.
Unlike most reptiles, sea turtles cannot retract their heads and flippers into their shells, which is why they have tough, streamlined shells for protection.
Sea turtles can hold their breath underwater for up to five hours, thanks to their ability to slow their heart rate to conserve oxygen.
The leatherback sea turtle, the largest of all sea turtles, can weigh up to 2,000 pounds and dive to depths of over 3,000 feet in search of jellyfish.
Sea turtles have an incredible sense of direction and can navigate back to the exact beach where they were born to lay their eggs, even after traveling thousands of miles.
Some sea turtles can live to be over 50 years old, with some reports suggesting they can even reach 100 years, making them some of the longest-living animals in the ocean.
