Sea turtles might not be bothered by jellyfish stings, as they are armored on the outside and the inside with spiky fingernail-like coating on their throats. However, turtles do eat a lot of jellyfish, and this jellyfish-rich diet is high in salt. To get rid of the extra salt, the turtles cry it out. They even have special salt glands that help them produce more tears. So, next time you’re feeling low, remember that crying can have real benefits for your body, even if you’re a sea turtle!
