Using a complex power amplification system, mantis shrimps ulitize a saddle‐shaped biospring to store and quickly release elastic energy, enabling them to deliver deliver ultra‐fast strikes on their prey. On page 6437, A. Miserez and co‐workers demonstrate that the saddle is a bi‐layer material with distinct degrees of mineralization. One layer is used to maximize elastic energy storage during loading, while the other layer provides flexibility and prevents fracture during repeated loading/unloading cycles.
