The club is a biological to study the growth and biomineralization of complex hard miner- hammer used by stomatopods to fracture the hard shells of their alized tissues. Arthropods are ideal model organisms to study preys and has emerged in recent years as a fascinating model biomineralization because they regularly molt their exoskeletons structure of bioinspired materials (6–10). The club is the most and grow new ones in a relatively fast timescale, providing oppor- mineralized appendage of the dactyl segment and exhibits a tunities to track mineralization of entire tissues.
