Found in coral reefs, rocky flats, reef sand, and seagrass habitats. This is one of the most successful "cleaner fish" in the tropical West Atlantic. It feeds on the parasites of other fish, who come to the wrasse to be cleaned. Most bluehead wrasses are yellow. The head of the terminal-phase male (about 4% of the population) is blue. Edibility is poor. Range is large, including both sides of the Atlantic, Bermuda, Bahamas, and Florida to Curacao, plus the Gulf of Mexico.
