Assessment rationale/justification
The Grey Sharpnose Shark occurs throughout UAE waters. It is reported as a dominant species in landings in several Arabian Sea countries and is particularly susceptible to a variety of inshore fisheries that operate throughout the region. Intensive and increasing fishing means that, like many other sharks, populations are likely to have declined. 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 20-30% over the past three generation lengths, or about 12 years. It is listed as Near Threatened, nearly meeting the thresholds for Vulnerable A2cd.

Threats listed in assessment
In the UAE sharks, have been impacted by targeted commercial fisheries until 2014 when a ban on export of sharks was imposed (Ministry of Climate Change and Environment). Sharks continue to be impacted by artisanal and bycatch fisheries (Annual Fisheries Statistical Report for Abu Dhabi Emirate 2001-2018), though catch data are not species-specific. Marine habitats in the region have experienced high levels of disturbance and are quickly deteriorating due to major impacts from development activities (Sheppard <em style=""font-variant-ligatures: normal;font-variant-caps: normal;orphans: 2; text-align:start;widows: 2;-webkit-text-stroke-width: 0px;text-decoration-style: initial; text-decoration-color: initial;word-spacing:0px"">et al. 2010).
