[17][18], More than 620 species are currently recognised in the family Alpheidae, distributed among 45 genera. Bioacoustician John Potter used this sound as an ‘acoustical illumination’ to resolve shapes … [12] In comparison, the surface temperature of the sun is estimated to be around 5,772 K (5,500 °C).

Other common names for animals in the group are pistol shrimp or alpheid shrimp. Alpheidae is a family of caridean snapping shrimp, characterized by having asymmetrical claws, the larger of which is typically capable of producing a loud snapping sound. When the snapping claw is lost, the missing limb will regenerate into a smaller claw and the original smaller appendage will grow into a new snapping claw. These relationships form for the mutual benefit of the fish and the shrimp. As you can see by the shrimp in this image, the snapping shrimp has one larger claw that's shaped like a boxing glove. When the bubble explodes, the sound is produced.
[9] It corresponds to a zero to peak pressure level of 218 decibels relative to one micropascal (dB re 1 μPa), equivalent to a zero to peak source level of 190 dB re 1 μPa m. Au and Banks measured peak to peak source levels between 185 and 190 dB re 1 μPa m, depending on the size of the claw. The collapse of that bubble causes an audible snap, which sends out shock waves that are powerful enough to kill small fish that the shrimp can then eat.

[6] So far this association has been observed in species that inhabit coral reef habitats. ThoughtCo uses cookies to provide you with a great user experience. The shrimp then extends its antennae outwards to determine if any fish are passing by.

They produce an extremely loud pop (source level 220dB re 1 uPa or 80 kPa at 4 cm). There are hundreds of species of snapping shrimp. This pop stuns their prey which they can then dismember and eat without further ado. This shrimp is known for its built-in 'stun gun', created by its snapping claw. The shrimp is nearly blind, so it is threatened by predators if it leaves its burrow. [4][15][16] The shrimp are a major source of noise in the ocean[4] and can interfere with anti-submarine warfare. Snapping shrimp have a relatively short lifespan of only a few years. The shrimp digs a burrow in the sand, which protects it and the goby with which it shares its burrow. When in colonies, the snapping shrimp can interfere with sonar and underwater communication. [citation needed]. Listening to the Ocean: Reading Audiographs, Timeline: The Roots of Understanding Sound, Distinctive for its disproportionately large claw, claw can be on either arm, no pincers, instead there is a pistol-like feature with a “hammer” that snaps and creates a cavitation bubble that is loud enough to stun their prey, Can share burrows with goby fish, live in colonies, snaps with claw to stun its prey, the sound can break small glass jars and can interfere with sonar and underwater communication, oral reefs, submerged seagrass flats and oyster reefs, orldwide in tropical and subtropical coastal waters.
