隆头鱼科的隆头鱼，特别是曲纹唇鱼（Cheilinus undulatus），或称拿破仑鱼，是红海珊瑚

species coexist, such as the checkerboard wrasse (Halichoereshortulanus), the fringed wrasse, the treacherous wrasse (Epibulus insidiator),the Maori wrasse (Cheilinus trilobatus), the cleaner wrasse (Labroidesdimidiatus), the bird wrasse (Gomphosus varius), the old wrasse and the girelles.The humphead wrasse is the largest wrasse, reaching up to 2.3 m in length and200 kg in weight, with a prominent frontal hump in adult males, thick lips and acolour ranging from blue-green to purple. Juveniles are smaller and differentlycoloured. These fish often change shape and colour during their lifetime, withsome adopting successive hermaphroditism, with females becoming males. Theyfrequent coral reefs, lagoons, outer slopes and sandy areas at depths of 1 to 100m. In the Red Sea, variants such as Cheilinus abudjubbe with pink lines and reddots can be found. Adults prefer deep, solitary areas, sleeping in crevices orenveloped in mucus. Carnivorous, they feed on hard-shelled invertebrates suchas molluscs, crustaceans, sea urchins, invasive starfish such as the crown-ofthornsstarfish, and sometimes fish eggs. The humphead wrasse controlspopulations that are harmful to corals. Some wrasses, such as the blue wrasse,act as mutualistic cleaners, removing parasites from larger fish. They swim usingtheir pectoral fins and live up to 30 years, often alone or in small groups.
