Unsurprisingly, the fine striped snapping shrimp gets its name from the snapping sound it makes when it shuts its two large claws. What you might not guess is that the loud noise does not come from the actual impact of the claws, but from the bursting of small bubbles of air trapped between them. The cracking sound of these exploding air bubbles—caused by the snapping claws of groups of shrimp —can be so loud that submarines can use it to hide from sonar, which detects an object’s position using echoes. Scientists think the shrimp makes this sound to stun its prey.
