Many species of this family are considered as collectible species because of the colors of their scales, being one of the favorites to find by divers in many regions of the world. Females are red-orange above to a pale or white ventral surface. These fish are found in all tropical regions of the world. Some of these prey items are toxic such as sea hares, boxfishes, and crown-of-thorns starfish. Coloration Individuals form small to medium-sized spawning aggregations, usually on outer reefs. As in numerous species of wrasses, some of the female humphead wrasses reverse sex to become males while other fish may start life as males.

Divers who observe a school of humphead wrasses feeing on a reef have been known to hear the noise and see the clouds of dust from the demolition of hard corals by this species. Subordinate males and females are smaller than dominant individuals and are often grayish with cryptic patterns. Upon hatching, the larvae settle out of the water and onto suitable substrate. They inhabit tropical reefs; at depths between 2 and 30 m the Indian Ocean from the Red Sea to the Gulf of Oman. Females rarely exceed about 3 feet (1 m) in length. Males range from a bright electric blue to green or violet blue. Wrasse inhabits coastal areas, rocky shores, coral reefs, tidal pools and sandy sea floor.

The pharyngeal teeth, a second set of dentition located inside the fish’s throat, enable the fish to crush prey items. Unsustainable consumption of live reef fish deprives them of their natural resources and potential food, and also eliminates key species from the marine ecosystem. The size of these fish varies from a few centimeters to more than 2 meters in length; some have cylindrical shapes while others have a deeper body.
