The pistol shrimp is no bigger than your finger.
And it's a crack shot.
One of its two claws functions just like a handgun-and other shrimp are targets.
When prey is in range, the claw is cocked.
The claw snaps shut so fast, it fires a bubble bullet-up to 62 miles an hour.
The bubble bursts and stuns the prey.
It all happens in a fraction of a second...the fastest gun in the sea.
