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.
The Madagascar hissing cockroach is one member of a group of roaches that can all hiss; this exact mode of sound production is atypical, as most insects that make sound do so by rubbing together various body parts ( stridulation ), such as legs. Madagascar hissing cockroach has been used as the driver of a mobile robot. They were used in the reality television series Fear Factor. The species also made an appearance in the movie Men In Black in 1997.
