The ability to roar comes from an elongated and specially adapted larynx and hyoid apparatus. The larynx is attached to the hyoid bone that is hanging from a sequence of bones. This sequence of bones the hyoid hangs from are tympanhoyal, stylohal, epihyal, and ceratohyal; these are located in the mandible and skull. In the larynx there are vocal folds that produce the structure needed to stretch the ligament to a length that creates the roar effect. This tissue is made of a thick collagen and elastic fiber that becomes denser as it approaches the epithelial mucosal lining. When this large pad folds it creates a low natural frequency, causing the cartilage walls of the larynx to vibrate. When it begins to vibrate the sound moves from a high to low air resistance which makes the roaring.
