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.
(ie only). Calves (young giraffes) bleat and make a mewing call, cows (female giraffes) seeking lost calves will bellow and courting bulls (male giraffes) may emit a raucous cough. Giraffes also give alarm snorts, whereby moaning, snoring, hissing and flute like sounds have been reported.
