Assessment rationale/justification
In UAE waters, this relatively deep-living, reef-associated species occurs only in the Sea of Oman. It is exploited in the UAE and surrounding waters of the Sea of Oman. Anecdotal observations reported by fishermen indicate catch of this species declined by about 80% over the past decade. The generation length is not known due in part to the lack of data on age at first maturity. In addition, fishing effort trends are poorly understood. Based on the concern for its population status in the face of possible ongoing overexploitation, and general lack of data, it is listed as Data Deficient. It is recommended to conduct life history studies and improve fisheries management.

Taxon distribution as listed in assessment
In UAE waters, this species occurs only in the Sea of Oman. A report of this species occurring in the Arabian Gulf from Blegvad (1944) is questionable (Carpenter et al. 1997b). Globally, it is widely distributed in the Indo-Pacific (Anderson and Allen 2001, Williams et al. 2006). Its depth range is 40 to 360 m (Anderson and Allen 2001).

Habitat
Habitat details as listed in assessment
This benthopelagic, reef-associated species occurs over rocky bottoms (Sommer et al. 1996). At night, it migrates vertically to the upper part of its habitat to feed on small fishes, shrimps, crabs, amphipods, ascidians and salps (Opic et al. 1994, Anderson and Allen 2001). Its maximum total length is 100 cm (Anderson 1986), but more commonly occurs to 50 cm standard length (Anderson and Allen 2001). Female fork length at first maturity ranges from 36 to 38 cm (Mees 1993).The maximum reported age is 44 years (Andrews et al. 2012).
Threats and conservation measures listed
Threats listed in assessment
Overfishing is a major threat to this species in 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).
