For Certain Shrimp, Life's a Snap

Science, 2000
On page 2114 of this issue, physicists report that a collapsing bubble outside the claw of the snapping shrimp Alpheus heterochaelis causes its characteristic clack. According to this new study, A. heterochaelis clamps its claw so rapidly that a water jet gushing from the claw first loses and then gains pressure, causing an air ...

Ecological generalism facilitates the evolution of sociality in snapping shrimps

Ecology Letters, 2017
AbstractEvidence from insects and vertebrates suggests that cooperation may have enabled species to expand their niches, becoming ecological generalists and dominating the ecosystems in which they occur. Consistent with this idea, eusocial species of sponge‐dwelling Synalpheus shrimps from Belize are ecological generalists with a broader host breadth ...

Acoustic particle motion detection in the snapping shrimp (Alpheus richardsoni)

Journal of Comparative Physiology A, 2021
Many crustaceans produce sounds that might be used in communication. However, little is known about sound detection in crustaceans, hindering our understanding of crustacean acoustic communication. Sound detection has been determined only for a few species, and for many species, it is unclear how sound is perceived: as particle motion or sound pressure.

Snapping Behavior of the Shrimp Alpheus californiensis

Science, 1973
A pair of very smooth disks, located on the claw of the snapping shrimp Alpheus californiensis , are temporarily held together by cohesive forces of water. This allows the closer muscle of the claw to generate a large amount of tension before these cohesive forces are overcome, and results in a rapid closing ...

Experimental induction of claw transformation in snapping shrimps

Journal of Experimental Zoology, 1988
AbstractThe effectiveness of various manipulations of the major claw in inducing the contralateral minor claw to transform into a major claw in adult snapping shrimps, Alpheus heterochelis, was studied. While removal of the major claw was 100% effective in inducing transformation, sectioning of its nerve was effective in about two‐thirds of the animals,

Redistribution of vocal snapping shrimps under climate change

Science of The Total Environment
A variety of marine organisms can produce sounds that are important components of the marine soundscape and play a critical role in maintaining marine biodiversity. Climate change has greatly altered the geographical ranges of many marine species, including sound-producing organisms.

The snapping shrimp conundrum: Spatial and temporal complexity of snapping sounds on coral reefs

Journal of the Acoustical Society of America, 2016
Snapping shrimp are abundant crevice-dwelling crustaceans worldwide. The short-duration broadband “snap” generated by the collapse of a cavitation bubble upon the rapid closure of their specialized claw is among the loudest bioacoustic sound in the sea.

Neuromuscular relationships during claw regeneration in Californian snapping shrimp

Journal of Experimental Zoology, 1984
AbstractWe have examined the innervation patterns of the two excitor axons to the closer muscle in the dimorphic (snapper and pincer) claws of Californian snapping shrimp (Alpheus californiensis). In both claws the fastcloser excitor (FCE) axon supplies all of the closer muscle fibers.

Snapping shrimp noise near Gladstone, Queensland

The Journal of the Acoustical Society of America, 1997
The intensity of the noise generated by snapping shrimp between 0.6 and 12.5 kHz was measured from Auckland Wharf to the end of the dredged channel leading into Gladstone, Queensland, Australia, and on a route out across to the edge of the Great Barrier Reef.

Estimating the polar distribution of snapping shrimp with a wide aperture array

ISSPA '99. Proceedings of the Fifth International Symposium on Signal Processing and its Applications (IEEE Cat. No.99EX359), 2003
A wide-aperture array consisting of three widely separated collinear hydrophones is used to estimate the polar distribution of underwater acoustic transients produced by snapping shrimp. Simultaneous differential time-of-arrival measurements from adjacent pairs of hydrophones are used to estimate the instantaneous range and bearing of the source of ...
