Does a turtle breathe through its shell?

Answer:

It does not. A turtle has lungs and so breathes through its mouth. It inflates and deflates its lungs by flexing muscles at its leg openings (which alter the size of its internal cavity). These muscles are used instead of the diaphragm since the diaphragm was lost when the turtles ribs fused to form their shell.
