How does pistol shrimp work?

Spread the love

When a pistol shrimp senses prey is nearby, it will open the top part of its big claw, allowing some water to enter a small chamber in the crook of the claw. Then, when it clamps down, the pressure from a small plunger on the top claw forces the water out of the chamber. This happens so fast that it creates bubbles.

How does a pistol shrimp generate heat?
