Snapping shrimp use headgear to protect their brains from shock waves: Unusual "hood" is the first known biological armor that protects against traumatic brain injury.

The article discusses the discovery of a unique biological armor in snapping shrimp that protects them from traumatic brain injury caused by their own high-speed claw snaps. Researchers from the University of South Carolina and the University of Tulsa found that these shrimp possess transparent hoods in their exoskeletons, which are effective at dissipating shock waves and reducing concussive forces on their heads. The study demonstrated that these hoods are significantly less stiff than the shrimp's hard shells, making them twice as effective at protecting against impacts. This finding represents the first known instance of biological armor designed to shield an animal from shock wave-induced brain trauma, with potential implications for developing protective strategies for humans.
