Snapping Shrimp / Brisbane River
1 sound
Snapping Shrimp, also know as Pistol shrimp or Alpheidae, are found worldwide with over 600 species living in oceans, rivers and freshwater catchments. The sound they emit could be likened to a crackling fire, but has the capacity to stun crabs and fish and reach an impressive 218 decibels.
The snapping shrimp has two claws, one which appears to be disproportionately large with two unique joints that create the distinctive sound. The speed in which the joint snaps shut creates a powerful wave that results in the loud popping sound. The sound is generated by the collapse of a cavitation bubble formed in an extremely rapid closure of their claw.
