Taxon distribution as listed in assessment
The Hardnose Shark occurs throughout UAE waters. Globally, it is widespread in the Indo-West Pacific, but has not been recorded from the Gulf of Aden or the Red Sea (Last and Stevens 2009).

Habitat details as listed in assessment
The Hardnose Shark is a small species of carcharhinid that occurs in inshore and offshore waters to depths of 170 m (Ebert et al. 2013). The species reaches a maximum size of 99 cm total length (TL) in the region (Jabado et al. 2015, Raje et al. 2015). Young are born at a relatively large size (47-49 cm TL), with females maturing at 81 cm TL and males at 75 cm TL (Jabado et al. 2015). Mature females probably have a two-year reproductive cycle, with only 2-3 pups produced per litter (Henderson et al. 2004, Jabado et al. 2016). Smart et al. (2013) reported in Australian waters that maximum age was about 12 years with maturity around 4 years. This suggests a generation length of 8 years. Based on these life history parameters it is likely to have a much lower level of productivity than other small species of carcharhinid sharks (e.g., Rhizoprionodon spp.) and so is more susceptible to fishing pressure.

Assessment rationale/justification
The Hardnose Shark occurs throughout UAE inshore and offshore waters. It is caught in subsistence, artisanal and commercial fisheries that utilize gillnets, lines and trawls throughout the Arabian Sea region. Inshore fishing pressure is intense throughout this species' range, and the highest levels of exploitation probably occur in the UAE, Iran, Pakistan and India. Although of small size, its life history may not be as productive as that of other small carcharhinids (e.g., Rhizoprionodon spp.), making it more susceptible to fishing pressure. Anecdotal information indicates that significant declines have occurred over the past 20 years in UAE waters. Individuals in the UAE are a component of a larger, interconnected and migratory population that occurs broadly in the north-western Indian Ocean. Given the intense fishing pressures faced by this species throughout the Arabian Seas, and ongoing threats from bycatch and habitat loss, it is inferred that declines reported in the Arabian Seas are representative of the status in the UAE. Based on fish market observations over time, 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 24 years. It nearly meets the thresholds for Vulnerable under criterion A2bcd, and is listed as Near Threatened.

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). This species continues 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).
