The Acoustic Mechanics Of Stick–Slip Friction In The California Spiny Lobster (Panulirus Interruptus), Sheila Patek, J. E. Baio

The dynamic interplay between static and sliding friction is fundamental to many animal movements. One interesting example of stick–slip friction is found in the sound-producing apparatus of many spiny lobster species (Palinuridae). The acoustic movements of the spiny lobster's plectrum over the file are generated by stick–slip friction between the two surfaces. We examined the microscopic anatomy, kinematics, acoustics and frictional properties of the California spiny lobster (Panulirus interruptus) toward the goal of quantitatively characterizing the frictional and acoustic mechanics of this system. Using synchronous high-speed video and sound recordings, we tested whether plectrum kinematics are correlated with acoustic signal …
