When a mantis shrimp (Crustacea: Stomatopoda: Odontodactylidae: Odontodactylus scyllarus) strikes at extreme speeds, cavitation forms between the appendage and the target. Cavitation itself causes extremely high pressure when the bubble collapses. Thus, in this video, the force from the impact itself, followed by the collapse of the cavitation bubble is visible. The strike was filmed at 100,000 frames per second and the force sensor was recorded synchronously at 500,000 samples per second. The video is played back at ~10 frames per second.
