Courtships sounds and associated behaviours were recorded in the Canestrini's goby Pomatoschistus canestrinii using a simultaneous video–acoustic system: the male exhibited a display composed of both a visual (rapid head movements) and an acoustic component (thump sound), and its intensity was positively associated with that of a female visual display.
