Potamalpheops is the only genus found in freshwater caves while Betaeus is found in cold seas. The pistol shrimp is one of the most powerful creatures on Earth, using its clever anatomy to kill its enemies with 8000-degree jet-propelled bubbles. 15. It cant kill you by snapping its claw.

If the goby gives the signal that danger is nearby, they both scurry back to their protective home. Given the power of the sound produced by the Pistol Shrimp, none other sound exceeds it in importance, since it is believed that it can even interfere with the measurement and recording of Bio Acoustic signals that submarines make in shallow waters. The physical phenomenon produced when the pincer closes, is known as cavitation, and it is a sound that reaches according to the experts, the two hundred and eighteen decibels. Upon closing the claw with impressive force, a plunger-like piece shoots the water out at speeds as fast as a car traveling down the highway. The adaptations of shrimp help them withstand short- and long-term environmental hazards and make them suited to live in extreme habitats. pop!, and take a moment to appreciate the teeny, tiny pistol shrimp, and the long evolutionary process that led to its extreme hunting technique.

The Pistol Shrimp has a special claw that can create a sound wave louder than a jet engine and as hot as the sun. To get the final conclusion , several laboratory tests were developed to different specimens, in different fields of study, and different populations from different habitats; in order to know the truth, since in 1887 the sound was mistakenly attributed to the opening of the dactyl.

When hunting, the shrimp usually lies in an obscured spot, such as a burrow. This produces a flash of light which lasts for no longer than 10 nanoseconds and is not visible to the naked eye. This peculiar characteristic of Pistol Shrimps was already known by scientists, who had studied the crustacean for a long time. This process can last between one and four months, then they will have already developed as adults, and will be sexually mature to reproduce.

It can be found either on the left arm or the right arm. When released, it snaps into the other part of the claw, emitting an enormously powerful wave of bubbles capable of stunning larger fish and breaking small glass jars.[5].
