What is a group of shrimp called?

"Pistol shrimp"

Pistol shrimp is a group of small shrimp that belong to the family Alpheidae. They are widely distributed in shallow coastal waters around the world, with more than 600 known species. Pistol shrimp are so named because they possess a unique ability to produce a loud snapping sound with their specialized claws. They use this sound as a weapon to stun or kill their prey and to communicate with other shrimp.

Pistol shrimp are usually less than 3 inches in length and have a transparent body with various shades of coloration, including red, pink, orange, and blue. They are primarily nocturnal and hide in burrows during the day. Pistol shrimp feed on small fish, crustaceans, and plankton, and they are an important food source for larger predatory fish.

Pistol shrimp have a symbiotic relationship with gobies, a type of small fish. The shrimp digs and maintains a burrow, while the goby stands watch for predators and alerts the shrimp to any danger. In return, the shrimp provides the goby with a safe home.

Overall, the pistol shrimp is a fascinating and ecologically important species that contributes to the biodiversity of marine ecosystems.
