GHARIB Posted August 26, 2020 Share Posted August 26, 2020 (edited) The pistol shrimp is a remarkable creature about 4 cm in length and 25 grams in weight. Despite its small size, it can move its claws at a speed of 97 km/hr. The speed of the snap is such that a bubble is created consisting of vacuum. The internal low pressure causes a water pulse that immobilizes prey with an associated noise of 218 dB which is louder than a bullet, and reportedly a temperature of 4800 degrees centigrade which is similar to the surface temperature of the sun, albeit over a very small area. Additionally, there is a brief flash of light . A pressure of 80 kPa at a distance of 4 cm from the claw has been measured, with the water jet traveling at 25 m/sec, enough to kill a small fish and it is this pressure which is significant for stunning prey rather than the heat and light. Pistol shrimp colonies generate so much noise – loud snapping sounds all day and all night – that they actually interfere with the Navy’s ability to use sonar technology for submarine detection. In fact, pistol shrimp are credited with aiding the U.S. during World War II Edited August 26, 2020 by GHARIB 2 1 1 Quote Link to comment Share on other sites More sharing options...
