Snakes breathe principally by contracting muscles between their ribs. Unlike mammals, they lack a diaphragm, the large smooth muscle responsible for inspiration and expiration between the chest and abdomen. Inspiration is an active process (muscles contract), whereas expiration is passive (muscles relax).
Turtles breathe air through external nares located above their mouths. Air moves through the glottis and into the trachea, made of a series of rings of cartilage. A turtle's trachea is elongated and flexible, allowing the turtle to move his head in and out of his shell.
