Abstract
Stop action cinematography was used to analyze the wave display of the fiddler crab, Uca pugilator. Thirteen spatiotemporal wave components were quantified for twenty‐eight males, which represented a size continuum from 7.0 to 18.0 mm carapace width. Individual components of the display appeared equally variable across the waves of a particular actor and the coefficient of variation did not change significantly from one animal to the next throughout the size continuum. The absolute temporal and spatial addresses of half of the components, including the duration and amplitude of the display, did change significantly with increased size.
