Appearance

Its color can vary between olive to more vibrant shades of green and purplish-blue, with a pattern of yellow undulating lines or reticulation on the head.

Males, typically larger than females, are capable of reaching up to 229 centimetres (90 in) and weighing up to 191 kilograms (421 lb), but the average length tends to be around 60 centimetres (24 in).

Range and habitat

The humphead wrasses can be found on the east coast of Africa around the mouth of the Red Sea, and in some areas of the Indian and Pacific Oceans. Juveniles are usually found in shallow, sandy ranges bordering coral reef waters, while adults are found mostly in offshore and deeper areas of coral reefs, typically in outer-reef slopes and channels, but also in lagoons.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Breeding

The humphead wrasse is long-lived, but has a very slow breeding rate. At certain times of year, adults move to the down-current end of the reef and form local spawning aggregations (groups).

In crisis

The species is one of the top predators of the reef ecosystem, mainly consuming various invertebrate species among them the crown-of-thorns starfish. The humphead wrasse is listed as endangered on the IUCN Red list and in Appendix II of CITES. Its numbers have declined due to multiple threats, among them: Intensive, species-specific removal by the live reef food-fish trade throughout its core range in Southeast Asia.
