Insights from probing the shock-absorbing layer within the crustacean’s club-like claw could inspire the design of tough new materials.

Mantis shrimp can deal incredible blows without damaging themselves, but how? The makeup of their armor is key.

“The periodic region plays a crucial role in selectively filtering out high-frequency shear waves, which are particularly damaging to biological tissues,” Espinosa said. “This effectively shields the shrimp from damaging stress waves caused by the direct impact and bubble collapse.”

Mantis shrimp are colorful creatures with an incredibly powerful punch — comparable to a .22 caliber bullet. This punch is strong enough to shatter shells and even glass. Luckily, mantis shrimp remain protective from the force of their own blows,
