“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 among the ocean’s most formidable predators, delivering one of the most powerful and fastest punches in the animal kingdom.

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

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,

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

A research team has taken inspiration from principles found in nature and developed the "hyperelastic torque reversal mechanism" (HeTRM), which enables robots made from rubber-like soft materials to perform rapid and powerful movements.
