Communication and Perception
Most wrasses rely on vision to find their prey. Visual recognition may also be important for terminal phase (TP) males to identify harem members. Although TP males are susceptible to streaking attempts by initial phase (IP) males (see Reproduction: Mating Systems), no IP males have been found in harem-forming species. This suggests that IP males are unable to mimic IP females, despite very similar morphology.
