Tiger Pistol Shrimp: The Reef’s Dynamite
The Tiger Pistol Shrimp (Alpheus bellulus), also known as the Tiger Snapping Shrimp or Pretty Shrimp, is a captivating and industrious marine invertebrate. Its common name comes from its striking coloration: a tan or yellowish-white body adorned with broken lines and irregular spots in shades of brown, orange, or dull red, giving it a tiger-like appearance.
This species is famous for its disproportionately large “pistol” claw, which it can snap shut with extreme speed to create a high-pressure cavitation bubble. The rapid collapse of this bubble produces an audible ‘snapping’ or ‘clicking’ sound—one of the loudest noises in the ocean—powerful enough to stun or kill small prey.

I’ve had this shrimp for three months and it’s been very active. The sound it makes when snapping is surprising and delightful. It doesn’t seem to harm other tank inhabitants and stays in one area, which is helpful for observation.
