The tiger pistol shrimp is arguably the loudest creature on earth. This little shrimp
is capable of snapping its claw and emitting a sound up to 200 decibels which it
uses to stun its prey. This process also creates a little bubble which – for a fraction
of a second – is hotter than the surface of the sun at 8,000F (4,426C).
The Tiger Snapping Shrimp may also be called Symbiosis Shrimp and Snapping Shrimp.
The body is tan with rust colored broken stripes running across the back. These beneficial
shrimp will constantly move gravel making them excellent sand stirrers in the reef
aquarium, as well as scavenging any uneaten food.
The sound it makes comes from an appendage on the pincher which moves when the pincher
is opened or closed and water is ejected. The Snapping Shrimp can be easily confused
with Mantis Shrimp if judged by sound only. Unlike the Mantis Shrimp, it is not harmful
and will not pose any threat in the tank, with the possible exception of very small
shrimp.
The name Symbiotic Shrimp comes from the equally beneficial relationship the Pistol
Shrimp has with gobies (e.g. Amblyeleotris or Stonogobiops). The goby, with better
eyesight, warns the shrimp of predators. The shrimp share its food with the goby.
Tiger Snapping Shrimp thrive in environments with sand, rock caves, and dim light.
If in pairs, one will often stand guard at the burrow while the other is inside.
The Pistol Shrimp are intolerant of copper or high nitrate levels, but need a correct
level of iodine in the water to promote proper molting.
Snapping Shrimp will accept any meaty freeze-
