Monday was World Sea Turtle Day, which means it’s the perfect time to show one of our favorite dopey sea creatures some much-deserved turtley love.
Below, 12 interesting facts about sea turtles, aka, the coolest surfers in the sea.
1. They’ve been around for a very, very long time.
The oldest known sea turtle fossils date back about 150 million years, making them some of the oldest creatures on Earth. Just for some context, dinosaurs became extinct 65 million years ago:
2. They really love to travel.
Leatherback sea turtles can travel more than 10,000 miles every year:
3. For sea turtles, home is where the heart is.

Sea turtles have glands that help to empty excess salt from their eyes, making it appear as though they’re crying, but not to worry, they're just doing some spring cleaning:
10. Their gender depends on how hot or cold their environment was while they were in their eggs.
