Habitat
Habitat details as listed in assessment
The Slender Weasel Shark is found inshore in shallow waters of the continental shelf to depths of 18 m (Compagno et al. 1996, Weigmann 2016). It reaches a maximum size of at least 85 cm with males reaching maturity at around 65 cm TL (Moore et al. 2012, Moore and Pierce 2013, Jabado et al. 2016). It is a viviparous species, giving birth to two pups per litter which are born at 35-40 cm TL. No age and growth data are available and generation length is estimated as 8 years based on data for the Hooktooth Shark (Chaenogaleus macrostoma) (Henderson et al. 2004).

Assessment rationale/justification
The Slender Weasel Shark occurs throughout UAE inshore waters and may be uncommon there. It is poorly known in general, in part due to confusion with other species. It is caught in inshore gill net, trawl and line fisheries in the Arabian Sea region where inshore fishing pressure is intense and increasing. There is also an ongoing decline in habitat quality due to coastal development, particularly in the Gulf. 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 30-50% over the past three generation lengths, or about 24 years. It is listed as 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. This species is impacted by bycatch fisheries that are active elsewhere in its range. 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).
