Threatening Gesture

Caption

American alligator (A. mississippiensis), threatening gesture. At Rockefeller Wildlife Refuge. The ears of Alligators are hidden under skin flaps right behind the eyes. Alligators use sounds for communication and to locate prey. The neural mechanisms underlying sound localization are an evolutionary stable feature across archosaurs, which include birds, the closest living relatives to crocodilians.
