Crab-Crushing Mantis Shrimp Study Could Lead to Human Body Armor

You won't be calling a guy a shrimp when he's wearing super strong mantis armor. 

Using electron microscopes, engineers have been studying how the mantis shrimp's strong hammer-like claws work at the molecular level, and have found that unlike many man-made materials, they are both stiff and tough.

The claws, which are used to smash mollusks and crabs, deliver blow after blow with the acceleration of a 0.22-caliber bullet without breaking or cracking. Scientists think that these thumb-splitters, as fishermen call them, might be able to help lead to super lightweight body armor and other biology-mimicking materials.
