This episode examines the role of female mate choice in the evolution of extravagant "showy" male ornamentation in social animals. We focus on the remarkable land fish -- the Pacific leaping blenny -- on the island of Guam. Topics include why females prefer males with large colourful ornaments, how differences in sexual selection across species and populations can generate diversity in male ornaments, and the role of physical constraints (e.g., locomotor performance) and predation on the expression of conspicuous male behaviour.
