Species
Taxon distribution as listed in assessment
This species occurs throughout UAE waters. Globally, it is restricted to the western Indian Ocean where it occurs from the Arabian Gulf to India (Bauchot and Smith 1984).

Habitat
Habitat details as listed in assessment
This species occurs in shallow coastal waters to moderate depths over reefs and adjacent habitats, as well as estuaries and the lower reaches of rivers (Bauchot and Smith 1984, Randall 1995, Kamrani et al. 2016). It is a protandrous hermaphrodite. At one year of age, 90% of the population are male with running milt, while the other 10% are immature, but the age at which sex change occurs is not known (Kime et al. 1991). The maximum total length is 50 cm (Randall 1995).

Assessment rationale/justification
This coastal species occurs throughout UAE waters. It is taken in commercial fisheries in the UAE and surrounding areas of the Arabian Gulf and Sea of Oman. Landings in Abu Dhabi declined in the late 2000s, but updated data are needed to discern trends since 2011. Based on the uncertainty regarding the population trend of this exploited species, it is listed as Data Deficient. Studies are needed to estimate life history parameters (age at sexual maturity and longevity) to calculate generation length. Improvements in fisheries management is also needed.

Conservation
Threats listed in assessment
Overfishing is a potential major threat to this species in the Arabian Gulf and Sea of Oman region, which includes the UAE. Corals in the UAE and Arabian Gulf have severely declined due to the increasing frequency of mass bleaching events caused by rising water temperatures, which is a consequence of climate change, as well as pervasive coastal development (Riegl et al. 2018, Burt et al. 2019).
