Taxonomic Notes
Carcharhinus dussumieri is part of the Carcharhinus seali-dussumieri group that has been revealed to consist of five species: C. dussumieri and C. sealei have recently been re-described, C. coatesi and C. tjutjot have been resurrected as valid species, and a new species, C. humani has been described (White 2012, White and Weigmann 2014).
Taxon distribution as listed in assessment
The Whitecheek Shark occurs throughout UAE waters. Globally, it occurs from the northern Arabian Sea in the Arabian Gulf to the southeast coast of India. Bonfil (2003) reported this species from the lower Red Sea and Gulf of Aden, but these records may have been of Human's Whaler Shark (Carcharhinus humani), which was only recently described from this area (White and Weigmann 2014).

Habitat details as listed in assessment
The Whitecheek Shark is a small species of carcharhinid shark that is common in inshore waters over soft substrates at depths of 0-100 m (Weigmann 2016). It reaches a maximum size of 114 cm total length (TL) (Raeisi et al. 2017). Size at birth is around 28-40 cm TL. This species is placental viviparous and produces litters of 2-5 each year. A study conducted off Iran in the Arabian Gulf reported a longevity of 8 and 13 years for males and females, and both females and males matured at lengths between 60 to 68 cm (Raeisi et al. 2017). Age at maturity data are not available for this species, but the Atlantic Sharpnose Shark (Rhizoprionodon terraenovae), which reaches a similar maximum size of 96 cm TL (Carlson and Baremore 2003), is applied as a proxy for age at maturity (3-4 years for females and 2-3.5 years for males). When applying an age at first reproduction of 3 years and longevity of 13 years, its estimated generation length is 8 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.

Assessment rationale/justification
The Whitecheek Shark is common throughout UAE inshore waters. Little specific data are available for this species in the UAE. It has a relatively low reproductive capacity, which causes it to be susceptible to over-exploitation, but it remains common in the Arabian Gulf. It is apparently highly migratory, and has slow life history characteristics including low fecundity and a low annual rate of population increase. Considering this, the species has a low capacity to recover from even moderate levels of exploitation. It is especially susceptible to exploitation (target and bycatch) in many largely unregulated gill net, longline and trawl fisheries that operate within its range outside and surrounding UAE waters. Some management measures are now in place in the Arabian Sea region, although domestic fisheries are likely to continue. Though data specifically from the UAE are not available, individuals in the UAE are a component of a larger, interconnected and migratory population that occurs broadly in the north-western Indian Ocean. It is inferred that declines reported in the Arabian Sea region are representative of its status in the UAE. Based on recorded levels of exploitation and decline in habitat quality, it is suspected to have declined by 50-70% over the past three generation lengths, or about 24 years. It is listed as Endangered A2cd.

Threats listed in assessment
Information pertaining to threats specific to the UAE are unavailable. This species is impacted by target (for fins and their valuable meat) and bycatch fisheries that are active elsewhere in its range. Marine habitats in the Arabian Gulf are experiencing high levels of disturbance and quickly deteriorating due to major impacts from development activities (including dredging and reclamation), desalination plants, industrial activities, habitat destruction through the removal of shallow productive areas and major shipping lanes (Sheppard et al. 2010).
