Supplementary audio recordings of the mantis shrimp's rumble (note: low frequency speakers are needed in order to hear first two sounds): A typical rumble lasting approximately 1 second. Accompanies Figure 2. An exceptionally long duration rumble produced over a period of 13 seconds. Accompanies Figure 3. A pulsed broadband rattle generated when mantis shrimp vibrate the exoskeleton against a plastic burrow. Accompanies Figure 4. |

Patek, S.N. and R. L. Caldwell. 2005. Extreme impact and cavitation forces of a biological hammer: strike forces of the peacock mantis shrimp Odontodactylus scyllarus. Journal of Experimental Biology 208: 3655-3664. Supplementary videos of cavitation and force generation: A peacock mantis shrimp (Odontodactylus scyllarus) strikes a force sensor. Filmed at 100,000 frames per second 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 per second. 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. |
