Bellowing. Bellowing is a common sound in the alligator world, and is prevalent in both Chinese and American alligators -- the only types of alligators that still exist. These husky, guttural and very intense sounds are often used as a means of expressing a specific locale.ome species of alligators are capable of communicating even before birth -- think the American alligator (Alligator mississippiensis), to be specific. These reptiles are the most talkative crocodilian species, and begin producing high complaining noises while living within the eggs.
Fish communicate with noises including grunts, chirps and pops, University of Auckland marine scientist Shahriman Ghazali has discovered according to newspaper reports Wednesday. All fish can hear, but not all can make sound-- pops and other sounds made by vibrating their swim bladder, a muscle they can contract, Ghazali told the New Zealand Herald. Fish are believed to communicate with each other for different reasons, including attracting mates, scaring off predators or orienting themselves. The gurnard species has a wide vocal repertoire and keeps up a constant chatter, Ghazali found after studying different species of fish placed into tanks.
