Here are a few strange facts you might not have known:
They are vocal
Though they don’t have vocal cords, turtles can still make sounds. They suck in air and then force it out of their lungs, which can create some pretty distinctive sounds. The red-foot tortoise makes a sound similar to the cluck of a chicken. The male Travancore tortoise lets out an ear-piercing whine, similar to the sound of an electric motor, when they’re looking for a mate. You’ll hear a loud yelping sound, similar to a dog’s, when the giant musk turtle is afraid or is under attack. Also a female leatherback sea turtle, when nesting, will make sounds that are similar to a human belching.
