But turtles don't have a diaphragm, which is all well and good, since the rigidity of their shells would prevent their ribs, which are connected to them, from expanding. Instead, turtles must move their limbs or neck, and utilize other muscles connected to the pleural cavity (the area around the lungs), to help them breathe.

Not all reptiles use body muscle-based breathing. Crocodiles and turtles have developed different methods for breathing. Crocodiles have a diaphragm which enables them to inhale air, while turtles, whose lung expansion is limited by their shells, have a thin muscle layer that lies on their lungs and expands and contracts to bring in air.


But some turtles can expand or contract the space within their body cavities to allow for breathing. Indian flapshell turtles have a muscular sheet around their lungs that can expand and contract to allow for respiration. Like snakes, some turtles, including the green sea turtle, must hold their breath while moving.


While most turtles have webbed feet, some, such as the pig-nosed turtle, have true flippers, with the digits being fused into paddles and the claws being relatively small. These species swim in the same way as sea turtles do (see below). Sea turtles are almost entirely aquatic and have flippers instead of feet.

They do indeed have lungs! What's unique about tortoises is that their ribcage is trapped in a rigid shell and cannot expand. Most animals, like us, breathe by expanding their ribcage and flattening their diaphragm (this is the sheet of muscle at the bottom of your chest cavity).
