, a highly diversified fish family, where sexual dimorphism is so pronounced that males, females and juveniles have often been described as separate species by early ichthyologists! Such color dimorphism is viewed as an adaptation to sexual selection and life in coral reefs, where it is more conspicuous than in other environments. Labrids play an important role in the trophic functioning of coral reefs due to their high abundance and diverse feeding behaviors, from small zooplanktivores, crustacean and mollusk feeders to large-sized piscivores.
