The broomtail wrasse (Cheilinus lunulatus) is a species of wrasse native to the Red Sea and Indian Ocean.
Cheilinus lunulatus can reach an average length of about 35cm (14inches), with a maximum of 50cm (20inches) in males. In adults, the head is large and bright green, with small spots. The lips are large and blue. The pectoral fins are yellow, while the abdominal, the anal, and caudal fins are dark blue. The body is yellow-green in the middle and dark purple in the other part. Close to the operculum is a characteristic bright-yellow marking on a black background. It has a long fringed caudal fin, resembling an old broom (hence the common name) or the tail of a crowntail betta. Females and juveniles show large, dark stripes on their flanks. This wrasse feeds mainly on molluscs and hard-shelled invertebrates. It is oviparous.
This species occurs in the Red Sea to the Gulf of Oman (mainly near Djibouti, Eritrea, the Seychelles, and Somalia). In the Indo-Pacific, it is replaced by the closely related Cheilinus trilobatus.
Broomtail wrasses can be found on coral reefs and on adjacent sand and seagrass habitats, at depths of from 2to.
