Fig. 1. The sound-producing morphology of the California spiny lobster
(Panulirus interruptus). A pair of plectrums (pink), an extension off
each antenna, rub posteriorly over the files (dark red) to produce sound. The
green arrow indicates the direction of the plectrum's movement when producing
sound. Inset: a mass-and-spring representation of the acoustic
stick–slip mechanism found in spiny lobsters
(Patek, 2002;
Patek, 2001). The plectrum
(pink) is modeled as a moveable component with a mass sandwiched between two
springs. The plectrum moves across the file (dark red), which is fixed in
place. Each time the plectrum slips, a pulse of sound is produced. Movie 1 and
Movie 2 in supplementary material show sound production and associated
morphology, respectively.
