This tiny Crinoid Snapping Shrimp is the tiniest of all the snapping shrimp, and the only one that is endangered. The snapping shrimp is often called the pistol shrimp because it comes with its very own “gun” by which it makes a loud cracking, shooting noise. It really only shoots air, but the stun gun is enough to knock out prey foolish enough to swim past.
Cannon ball! Photographer Seth Casteel, who has two dogs of his own, is an animal activist.
