Population [top]

Population:This species is common throughout its range, and can be locally abundant. It is uncommon in Banda Flores, Indonesia, where it was found at only three of the seven sites surveyed (Mous 2002).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found around coral reefs between 0-10 m depth (Sommer et al. 2006), in clean coastal waters to outer reef flats, often in the surge zone but also down to 15 m (Kuiter 2002).

Thalassoma purpureum and T. trilobatum (which have a similar geographic range, (Kuiter 2002)) have nearly identical initial (female) phases (Myers 1991), and only differ slightly in coloration and length of the head. Thalassoma purpureum has a slightly longer head and the female of this species is best distinguished by a V-shaped mark on the snout (Myers 1991, Kuiter and Tonozuka 2001). The initial phase has a vertical dark red line below the front of the eye, usually with a branch to the front of the snout (Westneat 2001). It is a protogynous hermaphrodite (DeMartini et al. 2005), and forms spawning groups (Squire and Samoilys unpub. in Claydon 2004).

Use and Trade [top]

Use and Trade: This species is taken in subsistence and recreational fisheries. It is also exploited for the marine aquarium fish industry (Randall et al. 1990)

Threats [top]

Major Threat(s): There are no major threats known for this species, although it is occasionally collected for the aquarium trade.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for this species. However, its distribution overlaps several marine protected areas within its range.
