Quick Summary

Courtship coloration is a biological trait used by animals to attract and arouse a mate, and to help distinguish between different species. This type of coloration is a form of advertising, providing easily perceived information about an organism's identity and intentions.1

Often, the male of a species exhibits brighter courtship colors than the female. These vibrant colors are frequently combined with specific movements and postures to enhance the visual display. In some cases, males gather in groups to compete for females, showcasing their colors and engaging in elaborate displays. Many fish also display significant color changes during courtship, with some changes being rapid and others long-term hormonal alterations.1

These displays can convey information about a male's fitness, influencing female choice and driving the evolution of elaborate ornamentation through sexual selection.2
