- Humphead Wrasse (Cheilinus undulatus) is widely distributed on coral reefs and inshore habitats throughout much of the tropical Indo-Pacific , but it is nowhere common. Wherever it is fished , even if only moderately, density quickly declines and it appears now to have disappeared from several locations. It is particularly heavily exploited at the centre of its range in southeastern Asia for the live reef fish trade. Fishery-dependent and trade-related data suggest overall declines of at least 50% over the last 30 years, which qualifies this fish for an Endangered listing. (Ref 100465)

Inhabits steep outer reef slopes , channel slopes , and lagoon reefs. Juveniles are encountered in coral-rich areas of lagoon reefs, where staghorn Acropora corals abound; also in algae reefs or seagrasses. Adults rove across the reefs by day and rest in reef caves and under coral ledges at night. May be found at depths of 1 to 60 meters.
Typically found in water with a depth of 0 to -100 meters (0 to -328 feet).
Biome: Marine .
In one study, small post-settlement humphead wrasses
were found in
a species of seagrass (Enhalys acoroides), four species
of hard coral
(three Acropora spp.
and Porites cylindricus),
and in the soft coral Sarcophyton sp.
(branching form; M
Tupper, pers. comm.
). After settlement
associated with reef or near-reef habitats
of seagrass beds
areas, with juveniles typically inshore
and the largest individuals
found in deeper waters of outer reefs or lagoons
(Myers 1999). Juveniles
of 3–20 cm TL
, and larger, occur in coral-rich areas of lagoon reefs,
particularly among live thickets of staghorn, Acropora spp.
, in seagrass beds, murky outer river
areas with patch reefs
shallow sandy areas adjacent
to coral reef lagoons, and mangrove
and seagrass areas inshore (Randall 1955, Randallet al.
1978, Myers 1999, J.H. Choat, pers. comm.
). Recruitment patterns
may vary considerably between years (M.A. Tupper, unpublished data
Adults are more common offshore than inshore, their presumed preferred
habitat being steep outer reef slopes
, reef drop-offs, reef tops
, reef passes, and lagoon reefs to at least 100 m.
They are usually found in association with well-developed coral reefs
(Vivien 1973, Randall et all. 1978, Winterbottom et
al. 1989, Allen and Swainston 1992, Sluka 2000). Typically they
are solitary or paired
, but have also been noted in groups of 3–7
individuals (Donaldson 1995). They appear to be somewhat sedentary
in that the same individuals, indentifiable by distinct
may be seen along the same stretch
of reef for extended periods.
Indeed, many commercial
dive sites have their ‘resident’ Humphead
Wrasse, a favoured species for divers
. Natural densities are evidently
never high, even in presumed preferred habitats. For example, in
unfished or lightly fished
areas, densities may range
from two to
rarely more than 10–20 individuals per 10,000 m² of suitable reef.
In fished areas, however, densities are typically lower by tenfold
or more, and in some places fish no longer
appear to be present.
Accounts of reproductive activity in the field reveal that, depending on location, this species spawns between several and all months of the year, in small or large groupings, that spawning coincides with certain phases of the tidal cycle, and that groups of spawning fish can form daily, at a range of different reef types. Spawning areas and aggregated adults have been noted regularly along specific sections of reef, sometimes associated with no obvious topographical features, sometimes close to the shelf edge on outer reefs, or adjacent to exposed reef passes near fairly steep drop-offs , or on mid-shelf (unspecified) reefs (P.L. Colin, J.H. Choat, R. Hamilton, S. Oakley, pers. comms.). The species is evidently a daily spawner that probably does not migrate far to its spawning site(s), spawning for extended periods each year, i.e. , a ‘resident’ spawner (Domeier and Colin 1997, P.L. Colin, pers. comm.): groups of up to 150 fish were observed in Palau along the shelf edge in a loose aggregation.
Probable spawning aggregations have also been noted on Australia’s Great Barrier Reef (GBR), Fiji, New Caledonia, and in the Solomon Islands. Although spawning was not always observed, aggregated fish were ripe , or exhibiting behaviour likely associated with spawning. On the GBR, aggregations of up to 10 large males and 20–50 smaller fish (35–95 cm TL) were noted (J.H. Choat, pers. comm.). GBR aggregations from the Ribbon Reefs and north of Jewell Reef, once noted to include hundreds of fish, are no longer known at the same sites (Johannes and Squire 1988, L. Squire, pers. comm.).
The longevity of this species is up to at least 32 years, with females outliving the males (the oldest female recorded was 32 years), and sexual maturity is reached at about eight years of age (Choat in Pogonosky et al. 2002). Histological studies show that sexual maturation is reached at a size of between 40 cm and 60 cm total length (Sadovy, unpublished data). This species is thought to be a protogynous hermaphrodite, with sex reversal occurring at about 15 years of age (Choat in Pogonosky et al. 2002). At a total length of approximately 111 cm (Lau and Li 2000). Males grow very rapidly (Choat in Pogonosky et al. 2002).
It feeds on a variety of molluscs , fishes , sea urchins, crustaceans and other invertebrates (Randall et al. 1997)..

- 9.8 Marine Neritic - Coral Reef
- 9.9 Marine Neritic - Seagrass (Submerged) [more info]
The species is hermaphroditic , changing sex from female to male. The sex ratio of samples and fish observed in the field is female biased. Under IUCN criteria for mature individuals , there should be a correction made to factor in the sex bias which effectively reduces substantially the estimates of fish numbers included in this assessment .
Usually solitary but may occur in pairs. Adults are known to occur largely on outer reef areas , often in association with channels and passes. Spawning aggregation sites have been reported from outer reef areas.
