This Shrimp Makes a Fake Gunshot

Transcripció

At first glance, it just looks like a small shrimp with one oversized claw.

But that claw snaps shut so fast it blasts out a jet of water, and the collapsing cavitation bubble makes the crack and faint flash.

That shockwave can stun prey, and the same snap also helps the shrimp defend itself from predators.

In reef life, that same claw supports hunting, burrows, and goby partnerships.
