When turtles breathe, they extend their necks to increase the volume of their lungs. By retracting or stretching their necks, they create a vacuum effect that draws air into their lungs. Unlike many other animals, turtles do not have diaphragm muscles, so they rely on the movement of their neck and limbs to facilitate breathing. This unique mechanism allows them to efficiently take in air while remaining largely submerged in water.
