Alligators do make noises. The best way to describe these noises is a rumbling bellow or a deep growl, almost resembling an echo.Alligatorâs may use these types of noises when they feel threatened or are acting aggressively to try and protect themselves or their young.n addition to these types of noises made, alligators when they are young and ready to hatch, are known to emit a high pitched croaking noise that is often referred to or described as a âyerpâ. This yerping sound stimulates the eggs of other hatchlings.
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.
