Schwimmende und ruhende Alligatoren. Gegenseitige Beißversuche und drohendes Maulöffnen. Gelegentliches Aufblasen der Kehlhaut.

Some alligators (Alligator mississippiensis) are swimming in the water or are resting on land. As one of them is approaching to another which is laying on the bank it opens its mouth threatening and only shuts it after some seconds. Smaller menaced alligators leave their resting place. In the shallow water one of the alligators tries to bite another one but retreats with its mouth halfe open. Eventually the throat of one of the animals is blown up.
