The tiger pistol shrimp lives in burrows in symbiosis with certain goby species such as Cryptocentrus cinctus, Amblyeleotris guttata or Stonogobiops yasha. The shrimp digs and maintains the burrows which are the dens for both animals, while the goby acts as a watchman, warning of danger the shrimp cannot see due to poor eyesight. [ 8 ]
The bigclaw snapping shrimp produces a loud, staccato concussive noise with its snapping claw. The sound is produced when the claw snaps shut at great speed creating a high-speed water jet. This creates a small, short-lived cavitation bubble and it is the immediate collapse of this bubble that creates the sound. [3] A spark is formed at the ...
Alpheus digitalis is a species of pistol shrimp in the family Alpheidae. [1] [2] The species was first discovered after a taxonomic study of a snapping shrimp from the genus Alpheus from Japan and the Gulf of Thailand, of which, it was found that two species was confounded under A.digitalis, which was originally described based on a single specimen possessing abnormal chelipeds.
Some sea animals have found ways to use cavitation to their advantage when hunting prey. The pistol shrimp snaps a specialized claw to create cavitation, which can kill small fish. The mantis shrimp (of the smasher variety) uses cavitation as well in order to stun, smash open, or kill the shellfish that it feasts upon. [63]

Alpheus deuteropus or the petroglyph shrimp is a snapper or pistol shrimp in the family Alpheidae. It lives on coral reefs in tropical parts of the Indian and Pacific Oceans and in the Red Sea, as a commensal of corals such as Porites lobata. Its presence among the lobes leaves tunnels, cracks and grooves in the surface. [2]
