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.
Can sharks hear a hum when something yummy is around? Sharks have keen hearing, a huge advantage in the ocean since sound travels both farther and faster in water. On top of that, sharks can pick up on very low-pitched noises known as infrasounds. Many oceanic sounds fall into this frequency range â a perfect example is the noise fish make when they're in trouble. Sharks hear this noise and know where they can track down some easy prey. Scientific studies have proven that when sharks pick up on infrasonic sounds â often their first clue about the location of prey â they usually swim over to the source in a hurry.
