A peacock mantis shrimp (Odontodactylus scyllarus) strikes a force sensor.
Filmed at 100 000 frames s-1 in color, this movie clip shows the mantis shrimp's dactyl heel striking a force sensor. The formation and collapse of cavitation bubbles are visible between the sensor's surface and the mantis shrimp's appendage.
Synchronous high-speed video and force output of a peacock mantis shrimp's strike.
Two force peaks are generated during the strike of a single raptorial appendage. This movie clip shows simultaneous high-speed video images and force sensor output, both sampled at 100 000 samples s-1. The first force peak is caused by the impact of the mantis shrimp's appendage against the force sensor. The second force peak is caused by the collapse of a cavitation bubble. Following the primary cavitation bubble collapse, the rebound phase of cavitation is visible in the form of a light cloud of cavitation bubbles, which eventually collapse with lower total forces than the first primary bubble collapse.
