The red muscle of the shark is aerobic, so it is primarily used for cruising, while the white muscle is anaerobic, and is used for sudden bursts of speed. The great white has myotomes (W-shaped muscles) that are enmeshed in the caudal fin, which allow the shark to move gracefully through water. The back and flank muscles of the shark attach to tough strands composed of connective tissue and takes the place of the sharks ribs. The infamous jaws of the great white operate by a series of loosely slung jaws connected to the jaw muscle. The palatoquadrate makes the jaws protrude forward and rotates the muscles causing the mouth to widen, making it easier to hunt.
