Many marine animals rely on sound for survival and depend on unique adaptations that enable them to communicate, protect themselves, locate food, navigate underwater, and/or understand their environment. They may both produce sounds and listen to the sounds around them.

Sounds are particularly useful for communication because they can exist used to convey a neat bargain of information chop-chop and over long distances. Changes in rate, pitch, and/or structure of sounds communicate different messages. In particular, fishes and marine mammals utilize audio for communications associated with reproduction and territoriality. Some marine mammals likewise use audio for the maintenance of grouping construction.

Like to sonar systems on ships, some whales use sound to notice, localize, and characterize objects. By emitting clicks, or short pulses of sound, these marine mammals can listen for echoes and detect objects underwater. This is calledecholocation. Some whales and dolphins use echolocation to locate food. They send out pulsed sounds that are reflected back when they strike a target. The assay of the echoes helps the animals determine the size and shape of an object, its location, whether information technology is moving, and how far away it is. Echolocation is an effective way to locate casualty and too helps whales and dolphins analyze their environment.

Many species of fish and aquatic invertebrates too use sound. Fishes produce various sounds, including grunts, croaks, clicks, and snaps, that are used to attract mates equally well as ward off predators.

The life history of many coral reef fishes includes a pelagic larval phase that metamorphoses to the juvenile stage. Tardily stage larvae and transforming juveniles need to reach suitable reef habitats to mature. There is some evidence that underwater reef sounds may be detected past coral reef fish (and invertebrate) larvae guiding them to littoral areas and allowing them to identify suitable settlement habitats [1] Simpson, S., Meekan, Yard., McCauley, R. and Jeffs, A.

Little enquiry has been washed on marine invertebrates that produce sounds. However, several marine invertebrates, including spiny lobsters and fiddler crabs, have been institute to produce sounds for defensive and courtship purposes. Some marine invertebrates use audio for other purposes. The cleaner shrimp announces itself as a cleaner and advertises its services by clapping 1 pair of its claws when reef fish approach.

Cleaner shrimps identify themselves as a "cleaner" and annunciate their services to reef fish by clapping their claws (chelipeds). The hungrier the shrimp, the more than clapping it does. In this video, i can watch a cleaner shrimp (small, transparent fauna at eye) clap/indicate to reef fish swimming nearby.
