Arthropod acoustic communication is a primary focus at the Patek Lab. Here you can find our acoustically oriented research projects along with sounds and video of spiny lobsters (Palinuridae) and mantis shrimp (Stomatopoda).
Extreme high speed video of cavitation during a mantis shrimp strike
A peacock mantis shrimp (Crustacea: Stomatopoda: Odontodactylidae: Odontodactylus scyllarus) strikes a force sensor with its raptorial appendage. This video is a close-up view of the mantis shrimp's "hammer" (the dactyl) and was filmed at 100,000 frames per second (played here at ~ 10 frames per second). Cavitation is visible between the appendage and the force sensor.
