Taxon distribution as listed in assessment
The Arabian Smoothhound occurs throughout UAE waters (Randall 1995, Environment Agency Abu Dhabi unpublished data). Globally, it is moderately widespread in the Northern Indian Ocean from the Red Sea to India and Sri Lanka. Taxonomic issues have confused the distribution of this species in eastern India and Sri Lanka, and the full distribution of the species remains to be resolved.
Habitats and Ecology

Habitat
Habitat details as listed in assessment
This is a bottom dwelling shark found inshore and offshore at depths of 0-250 m, sometimes in association with coral reefs (Compagno 1984). The species is reported to reach a maximum size of 150 cm total length (TL) but is rarely seen above 100 cm TL (Jabado et al. 2016, Moore et al. 2016). Males mature at 65-78 cm TL and females mature from about 73 cm TL. Reproduction is viviparous, and the species gives birth to 2-16 pups per litter (Moore et al. 2016). Size at birth is reported as 26-28 cm TL (Bass 1986). No ageing data is available. Generation length is estimated as 10 years based on the Narrownose Smoothhound (Mustelus schmitti) from Brazil which has a similar distribution and maximum size.

Assessment rationale/justification
The Arabian Smoothhound occurs throughout UAE inshore and offshore waters, and may be relatively common there. It is taken as bycatch in some parts of its range, but remains common in landings. This species is not targeted in the UAE, trawling has been banned there since 1980 and it apparently remains common. Based on the lack of evidence for declines, continued importance in fisheries landings and relatively high biological productivity, this species is listed as Least Concern.

Conservation
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).
