Researchers at the University of Pennsylvania have discovered how the Pacific midshipman fish can hum continuously for up to an hour in order to attract potential mates. The study, which is featured on the cover of the January 2018 issue of the Journal of General Physiology, explains how the muscle fibers surrounding the fish's swimbladder can sustain the high rates of contraction--up to 100 times per second--that are needed to produce the animal's distinctive call.
