Conservation Status
Assessed as
Least Concern
Criteria system used
IUCN
(see Assessment details)
Assessment rationale/justification
This relatively deep-living, reef-associated species occurs throughout UAE waters. Fishing activity is not known to be causing declines in the UAE. There are no known major threats; therefore, it is listed as Least Concern in the UAE.

Taxon distribution as listed in assessment
This species occurs throughout UAE waters (Jawad et al. 2018). Globally, it is widely distributed in the Indo-Pacific (Allen 1985), but some exclude it from the Arabian Sea (R. Myers pers. comm. 2015). Its depth range is 40 to 245 m (Anderson and Allen 2001).

Habitat details as listed in assessment
This deepwater, demersal species inhabits tropical and sub-tropical waters (Allen 1985). It schools in areas of hard, rocky and uneven sea floor near steep drop-offs (Parrish 1987). It consumes fishes, shrimps, crabs, lobsters, stomatopods, squids, gastropods and urochordates (Allen 1985). Its maximum total length is 90 cm (Anderson 1986). The maximum age is about 18.2 years, the age at maturity is 3.2 years, the reproductive lifespan is estimated at 15 years, and the natural mortality is 0.35 (Martinez-Andrade 2003). The maximum age from Australia is 30 years at 81 cm total length and age at 50% maturity is 8 years at 55 cm total length (Flood et al. 2014). When applying an age at first reproduction of 8 years and longevity of 30 years, its estimated generation length is 19 years based on the following equation recommended by the IUCN Red List methods: Age at first reproduction + (Age at last reproduction -“ age at first reproduction)/2.
Threats and conservation measures listed
Threats listed in assessment
The protracted longevity, moderately slow growth and low natural mortality rates makes this species vulnerable to overfishing (Newman and Dunk 2002), but fishing activity is not known to be driving declines in the UAE at this time. 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).
