Colony species exhibit some of the most unique behaviors on the planet. Due to their highly complex social systems, colonies can work efficiently together for the group’s well-being. One of these species is the snapping shrimp. This YouTube Short by @Animal.lifeCBP shows off a colony and some of their amazing defense mechanisms. Read on to learn more about these fascinating shrimp!

About Snapping Shrimp
Snapping shrimp, also known as pistol shrimp, are part of the family Alpheidae, which includes over 620 different species. These shrimp inhabit coastal waters around the world, including both warm and some temperate regions, living in coral reefs and sea sponges. While most species in this family live alone, a few—particularly some in the genus Synalpheus—exhibit eusocial behavior, where a single reproductive female leads the colony, similar to a queen in insect societies. Despite their tiny size, at roughly an inch long, snapping shrimp are highly territorial. Their strong defense is part of why they get their name. Snapping shrimp have powerful snaps, and when their claws snap shut, a jet of water shoots out at around 72 miles per hour. The bubble produced collapses under the pressure of the ocean, increasing its temperature to around 3,800 degrees Celsius (about 6,900 degrees Fahrenheit).
Colony Life
Snapping shrimps have a unique colony system. The queen shrimp runs the colony, producing eggs for future generations. One amazing feature of these colonies is how the queen maintains her offspring. The queen releases chemicals that prevent her daughters from reproducing, turning them into workers. While some shrimp clean around their home, others become soldiers that defend the colony. Due to the number of intimidating predators that these shrimp face, they have grown to learn to defend themselves. By producing a clicking sound with their claws, they alert other shrimp in the colony. This summons the soldier shrimp, who then use their jet-like blasts to deter any predators that have infiltrated the colony. These shrimp are truly fascinating to see in action!
