Abstract: | The fiddler crab Uca tangeri communicates using a visual waving display and a vibratory drumming signal, both thought to function in mate attraction.
Using video playback techniques, images of an empty mudflat, a waving male, a threatening male, and a wandering female were
presented to male subjects. All stimuli elicited similar levels of low-intensity waving, but significantly more high-intensity
waves were elicited by the female and threatening male stimuli than the mudflat stimulus or the waving male stimulus. This
concurs with other research that the waving display is used at a higher intensity to attract females. The threatening male
stimulus failed to elicit the same response as an actual threatening male and we discuss the likely reasons for this. The
subjects also spent a significantly greater proportion of time drumming during the male waving stimulus than during the female
stimulus, suggesting that drumming functions in male-male competition as well as female attraction.
