隆头鱼科的隆头鱼，特别是曲纹唇鱼（Cheilinus undulatus），或称巨型隆头鱼，是红海珊

species coexist, such as the checkerboard wrasse (Halichoeres hortulanus), the fringed wrasse, the treacherous wrasse (Epibulus insidiator), the Maori wrasse (Cheilinus trilobatus), the cleaner wrasse (Labroides dimidiatus), 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 and 200 kg in weight, with a prominent frontal hump in adult males, thick lips and a colour ranging from blue-green to purple. Juveniles are smaller and differently coloured. These fish often change shape and colour during their lifetime, with some adopting successive hermaphroditism, with females becoming males. They frequent coral reefs, lagoons, outer slopes and sandy areas at depths of 1 to 100 m. In the Red Sea, variants such as Cheilinus abudjubbe with pink lines and red dots can be found. Adults prefer deep, solitary areas, sleeping in crevices or enveloped in mucus. Carnivorous, they feed on hard-shelled invertebrates such as molluscs, crustaceans, sea urchins, invasive starfish such as the crown-of-thorns starfish, and sometimes fish eggs. The humphead wrasse controls populations that are harmful to corals. Some wrasses, such as the blue wrasse, act as mutualistic cleaners, removing parasites from larger fish. They swim using their pectoral fins and live up to 30 years, often alone or in small groups.
