Pistol Shrimp

Pistol Shrimp

Pistol Shrimp is a strong crustaceans. It can cripple prey by it's strong  pistol sound . It is 2.5 centimeters long. It shoots it's bullet at the speed of  65 km / seconds.

Ecology

Social behavior has been discovered in the genus Synalpheus. The species Synalpheus regalis lives inside sponges in colonies that can number over 300 members. All of them are the offspring of a single large female, the queen, and possibly a single male. The offspring are divided into workers who care for the young and soldiers who protect the colony with their huge claws, most of which are male.

Snapping effect

The snap can also produce sonoluminescence from the collapsing cavitation bubble. As it collapses, the cavitation bubble reaches temperatures of over 5,000 K (4,700 °C). In comparison, the surface temperature of the sun is estimated to be around 5,800 K (5,500 °C). The light is of lower intensity than the light produced by typical sonoluminescence and is not visible to the naked eye. It is most likely a by-product of the shock wave with no biological significance. However, it was the first known instance of an animal producing light by this effect. It has subsequently been discovered that another group of crustaceans, the mantis shrimp, contains species whose club-like forelimbs can strike so quickly and with such force as to induce sonoluminescent cavitation bubbles upon impact.

SAVE ANIMALS

—It's super-easy to help animals, no matter how old you are. Check out how Save Animals to get a jump-start on making a huge difference in the lives of animal everywhere: Animals are alive for their own reasons, not to entertain us. Animals in movies, circuses, and zoos are denied everything that is natural and important to them. They will never be allowed to hang out with their families, graze, or do anything that they would do in the wild. Refuse to support this cruelty by never going to a zoo, marine park, or circus that uses animals. If your class is planning on dissecting any animal, ask your teacher for a humane alternative assignment, such as using a computer program to perform a virtual dissection. An animal will be saved, and you will actually learn and remember way more! Check out more info on how to get a dissection alternative at your school.
