What is a pistol shrimp goby?

Modern people love to eat seafood products, because seafood tastes very delicious and has high nutritional value. With the development of modern technology, a lot of seafood can be easily transported to distant places, providing people with a constant supply of fresh taste experiences. However, there are many types of seafood products and huge quantities, but people know very little about them. Let me introduce to you what pistol shrimp and goby are? I hope everyone can understand.

The pistol shrimp, also known as the drum shrimp, is mud green in color and has a pair of claws, one large and one small. Its body is about 5 cm long, but the giant claw is 2.5 cm long. They live in shallow waters of tropical oceans. When hunting, they quickly close their huge claws and spray out a stream of water at a speed of up to 100 km/h, which can stun or even kill their prey (such as small fish, shrimps, crabs, etc.). Such high-speed water flow will cause cavitation, forming extremely small low-pressure bubbles. These bubbles take only one billionth of a second from being emitted to bursting, and the temperature can reach 4700 degrees when they explode, so they can easily capture prey. When the water pressure returns to normal, the bubbles burst with a popping sound. If a group of pistol shrimp close their giant claws at the same time, the sound they make is enough to allow a submarine to evade sonar detection.

Goby is a general term for all goby species in the family Gobyidae. Each of them has a name that matches its own characteristics, such as "dwarf goby", "common goby", etc. Although they all look stupid and most are short, only a few centimeters long, they are the largest family of fish, with more than 2,100 known species.

The above is an explanation of what pistol shrimp and goby are. These two creatures are relatively unfamiliar to people, but as people continue to develop seafood, more and more people can enjoy the deliciousness of this peculiar seafood creature, adding different fun to life. However, some unknown seafood still requires people to thoroughly understand its characteristics before eating to ensure safety.
