<ul><li>Researchers at Northwestern University have identified a structure within the mantis shrimp that filters out harmful frequencies, allowing it to use shock waves to strike and kill prey without damaging its own tissues.</li><li>The finding could lead to the development of novel advanced protective materials for military and civilian applications.</li><li>The shrimp's unique structure consists of a hard hydroxyapatite coating, mineralized chitin fibers, and a Bouligand structure that features phononic bandgaps.</li><li>The phononic shield could inspire the design of protective materials for helmets, personnel armor, and packaging for sensitive devices.</li></ul>
