Title:	Alligators Shift Lungs to Maneuver in Water - http://www.reuters.com/article/scienceNews/idUSN1331444120080313
Description:	Unlike other stealthy swimmers, alligators lack the fins and flippers that help aquatic creatures maneuver in water. Despite the drawbacks caused by the absence of such specialized appendages, these powerful reptiles easily glide through the water in silence. Researchers have determined that alligators manage this feat by utilizing their unique ability to shift the positioning of their lungs within their bodies, thereby adjusting their buoyancy. The diaphragm, pelvic, abdominal, and rib muscles work together to force the lungs toward the tail for diving, toward the head for surfacing, and sideways to roll.
