Habitat details as listed in assessment
This species inhabits coral reefs typically along continental coastlines and large islands (Carpenter et al. 1997a, Grandcourt et al. 2005). Juveniles often occur in estuaries over sand, mud and gravel substrate and amongst mangroves (Kailola et al. 1993, Randall et al. 1997). It primarily consumes fishes, shrimps, crabs and other benthic crustaceans (Grandcourt et al. 2005). Its maximum total length is 172 cm and is a diandric protogynous hermaphrodite (Grandcourt et al. 2009). Juvenile sexual differentiation in this species can be significantly influenced by social factors (Liu and Mitcheson 2011). In the Arabian Gulf, it has been aged to at least 22 years (Mathews and Samuel 1991, Grandcourt 2006, M. Abdullah pers. comm. 2010). Females reach first maturity at 4 years and 34 cm total length. Males reach maturity at 67.5 cm and 7.5 years and transition occurs at 50 to 75 cm at 4 to 8 years of age (M. Abdullah pers. comm. 2010). McIlwain et al. (2015) reported a size and age at 50% maturity for females of 58 cm total length and 4 years. Based on a longevity of 22 years, age of first maturity of 4 years, and applying the mean generational turnover formula in Depczynski and Bellwood (2006), one generation length is estimated to be 12.5 years. It forms seasonal spawning aggregations in the Arabian Gulf from March to June (Heemstra and Randall 1993, Grandcourt et al. 2009).

Assessment rationale/justification
This demersal species inhabits nearshore habitats from estuaries (juveniles) to coral reefs (adults) throughout UAE waters. It is heavily targeted by grouper fisheries throughout the Arabian Gulf and off Oman. It is considered overexploited in the UAE, Oman and the Gulf. In addition, degradation of coral reefs and estuaries is pervasive throughout the Gulf, and is also impacting this species. According to fish market observations, catch data and biomass estimates from scientific surveys, this species has undergone an inferred decline of at least 20-45% and possibly more, since about 1998, or over the past two generation lengths. Conservation measures, including protected areas and fishing regulations (minimum catch length and some fishing license control in Abu Dhabi), have prevented the rate of decline from exceeding 50% at this time; however, fishing effort exceeds sustainability, causing overexploitation to continue. Fishing effort is expected to remain the same or increase in the future time period over the next generation length. Population(s) in areas neighboring the UAE are also in serious decline and it is unlikely that fishing effort is decreasing at a significant level elsewhere. Therefore, this species is listed as Vulnerable A2bcd+4bcd.

Conservation
Threats listed in assessment
Overfishing is a major threat to this species in the Arabian Gulf (Grandcourt et al. 2005). Degradation of estuaries (juvenile habitat) due to coastal development and pollution may also impact this species. The effects of reduced discharge of the Shatt Al-Arab River caused by damming of the Tigris and Euphrates Rivers has greatly impacted the estuarine habitats in the northern Gulf (Al-Husaini et al. 2015), and caused reduced recruitment in this species (Ben-Hasan et al. 2018). Chlorinated-hydrocarbons (sourced from pollution) have been detected in this species in sampling conducted in the UAE, and this is considered to be an additional stressor to the health of adults of this species (De Mora 2005). Corals in the UAE and Arabian Gulf have severely declined due to the increasing frequency of mass bleaching events caused by rising water temperatures, which is a consequence of climate change, as well as pervasive coastal development (Riegl et al. 2018, Burt et al. 2019).

Habitat details as listed in assessment
The Zebra Shark occurs in tropical and subtropical, shallow inshore and offshore waters, often found on and around coral and rocky reefs and on sandy plateaus near reefs, at depths down to at least 62 m. It is often observed resting on the bottom as well as swimming near the surface as both juveniles and adults. The species undergoes seasonal movement patterns, forms aggregations and demonstrates strong site fidelity to particular reefs (Dudgeon et al. 2013), which may make them more susceptible to targeted fishing.The Zebra Shark is an oviparous species. Size at birth ranges between 20 and 36 cm total length (TL). Reproductive periodicity in the wild is unknown. Captive aquaria animals have demonstrated annual egg laying periods of up to 3 months with 40-“80 eggs laid per year (Robinson et al. 2011) with up to 25% of eggs resulting in hatchlings (L. Squire Jnr pers. comm. 22/07/2014). Age of maturity of captive female sharks is approximately 6-8 years of age based on the commencement of egg laying (Thomas pers. comm. 18/02/2015, Robinson pers. comm. 11/01/2015) and 7 years of age for males (Watson pers. comm. 18/02/2015). Adults reach a maximum size of 246 cm TL with no sexual dimorphism evident (Dudgeon et al. 2008) and live over 28 years in aquaria (Thomas pers. comm. 17/02/2015). Generation length estimates based on 6 years first age at maturity and 28 years maximum longevity for female sharks is 17 years.

Taxonomic Notes
The nomenclatural history of the species is somewhat complicated. The name Stegostoma fasciatum (Hermann, 1783) has been the standard name used, however Dahl et al. (2019) concluded that the original name Stegostoma tigrinum Forster, 1781 is the correct senior synonym.
Taxon distribution as listed in assessment
The Zebra Shark occurs throughout UAE waters (Field 2005). Globally, it is found in inshore waters of the continental and insular shelves of the Indo-West Pacific (Compagno 2001).

Assessment rationale/justification
The Zebra Shark occurs throughout UAE coastal waters usually near coral and rocky reef habitat, and is relatively common there. It is susceptible to capture in a range of inshore fisheries, but is rare in landings in the UAE due to its relatively low value. This species is not targeted or valued in markets of the UAE, trawling has been banned there since 1980 and it remains commonly sighted by divers. It has strong site fidelity and can form aggregations, which can facilitate the rapid removal of individuals in fisheries operations. In the Arabian Sea, it is landed in India and Pakistan, but less commonly elsewhere. It is especially susceptible to exploitation (target and bycatch) in many largely unregulated gill net 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 at least 30% over the past three generation lengths, or about 50 years. It is listed as Vulnerable A2cd.

The Snaggletooth Shark occurs on the continental shelf from inshore waters to 130 m depth (Compagno 1998). This species attains 281 cm total length (TL), with males maturing at approximately at 122-131 cm TL (Jabado et al. 2016). This viviparous species has a seasonal reproductive cycle, producing 2 to 11 (mean = 6) young per litter. Size at birth is up to 38 cm TL (Henderson et al. 2004). Smart et al. (2013) provided age and growth data for specimens caught off the east coast of Queensland (Australia). Growth appears to be quite rapid, with maturity reached in 2-“3 years. Maximum observed age was 15 years. Generation length is estimated to be 9 years based on age data from Smart et al. (2013).

Assessment rationale/justification
The Snaggletooth Shark occurs throughout UAE coastal waters and is uncommon there and in surrounding areas. It is taken in a variety of fisheries in the Arabian Sea region. While there is limited information available on this species in the region, its large size, relative rarity, and the presence of intensive fisheries mean that, like many large carcharhinids (that are morphologically and ecologically similar to hemigaleids) in the region, it will have undergone significant declines. 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 27 years. It is listed as Vulnerable A2cd.

This species occurs mainly near the coast in shallow bays and off river mouths (Last et al. 2016). Maximum size is unknown but it attains at least 200 cm total length (TL) with males mature at about 130 cm TL (Last et al. 2016). Size at birth is unknown, although the closely related R. djiddensis is born at about 60 cm total length (TL). Maximum age for Rhynchobatus spp. in Australia is 5 years (males) and 12 years (females), but these data were not from the largest individuals (White et al. 2014) and are not reliable for the estimation of generation length. This is therefore estimated from the maximum age (19 years) and age at maturity (7 years) taken from the growth curve provided by White et al. (2014) for the Giant Guitarfish (Glaucostegus typus), which gives an estimated generation length of 13 years.

Taxonomic Notes
Rhynchobatus laevis is part of the Indo-West Pacific Rhynchobatus djiddensis species-complex. The name R. djiddensis has previously been used widely, leading to poorly-defined taxonomy and distributions for members of the complex (in particular, R. australiae, R. djiddensis, and R. laevis). Rhynchobatus yentinensis Wang, 1933 (described from China) might be applicable to this species or may be a synonym of R. springeri. Further investigation into the taxonomy of 'whitespotted wedgefish' is required, and additional species are likely to be described in the future.
Taxon distribution as listed in assessment
The Smoothnose Wedgefish occurs throughout UAE waters. Globally, it has a poorly-defined distribution in the Indo-West Pacific due to difficulties in distinguishing between species of Rhynchobatus (Last et al. 2016). It is confirmed in the Arabian Gulf and Sea of Oman (Giles et al. 2016).

Assessment rationale/justification
The Smoothnose Wedgefish occurs throughout UAE inshore waters in shallow bays and off river mouths. There has been a total ban on fishing for this species in UAE waters since 2019. The similarity of the three species of Rhynchobatus that occur in the region mean there are few reliable species-specific data available. It is commonly taken as bycatch in gillnet, longline and trawl fisheries and its fins are highly valued in international trade. Coastal development is causing habitat degradation, which may also be impacting this species. Significant declines are known in India, southern Oman, Pakistan and Iran. Little is known on the population of this species in UAE waters. It exhibits 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, landings data and decline in habitat quality, it is suspected to have declined by 50-80% over the past three generation lengths, or about 39 years. It is listed as Endangered A2bcd.

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.

The Milk Shark is a common continental shelf species that mostly inhabits muddy waters in coastal areas to about 50 m depth (Weigmann 2016). Across its range, it is reported to reach a maximum size of 178 cm, however, in the Arabian Seas region, the largest specimen recorded is 98 cm TL (Jabado et al. 2015). Females reach maturity between 59.7-74 cm TL and males between 60-76.5 cm TL (Henderson et al. 2006, Moore et al. 2012, Jabado et al. 2015, Shaaban et al. 2018, Sen et al. 2018). Off northwest India, it reaches maturity at the end of its second year and is a moderately fast-growing species of shark (Sen et al. 2018). Its natural mortality rate off northwest India was estimated as 0.61 year<sup>-1</sup> (Sen et al. 2017). It has a very productive life history being born at around 35-37 cm TL, maturing at young ages (2-3 years), producing 2-8 young every year and living up to 10 years (Henderson et al. 2006, Kizhakudan et al. 2015). Generation length is estimated at 5.25 years (Compagno 1984, Last and Stevens 1994).

Assessment rationale/justification
The Milk Shark occurs throughout UAE waters. It is very commonly taken in a wide range of artisanal, subsistence and commercial fisheries, and is often the dominant shark species in landings in the UAE. Inshore fishing pressure is intense and intensifying in parts of the Arabian Sea, and its abundance is suspected to have declined due to fishing. 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. Given the intense fishing pressures faced by this species throughout the Arabian Seas (and until recently, in the UAE), 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 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 15 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).

The Bowmouth Guitarfish has an intertidal and coastal distribution. It generally occurs close inshore and around coral reefs to about 90 m (Fricke et al. 2011). It occurs on or close to the seabed, mainly over sandy or muddy substrates. Very little is known about the life history characteristics of this species. However, it is a large species growing to at least 294 cm total length (TL) and is lecithotrophic viviparous (Compagno and Last 1999, Jabado 2018). Males mature between 150 and 175 cm TL, and one pregnant female was recorded with 9 mid-term embryos ranging between 27-31 cm TL (Last and Stevens 2009). A single new born individual of 53 cm TL has been recorded from Bahrain (Randall 1995). Further research on the biology and life history of this species is needed.Maximum age for Rhynchobatus spp. in Australia is 5 years (males) and 12 years (females), but these data were not from the largest individuals (White et al. 2014) and are not reliable for the estimation of generation length for rhinids. This is therefore estimated from the maximum age (19 years) and age at maturity (7 years) taken from the growth curve provided by White et al. (2014) for the Giant Guitarfish (Glaucostegus typus), which gives an estimated generation length of 13 years.

Assessment rationale/justification
The Bowmouth Guitarfish occurs throughout UAE inshore waters. This species is not targeted in the UAE and trawling has been banned there since 1980; however, it is frequently taken as bycatch in coastal net fisheries. It is taken in variable quantities in gill net and trawl fisheries elsewhere in the Arabian Gulf, and coastal habitat degradation is a significant threat, particularly in the Gulf. It is under extremely intense and increasing demersal fishing pressure in much of the Arabian Sea region. It exhibits 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 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 39 years. It is listed as Vulnerable A2cd.

Threats listed in assessment
This species is impacted by fishing activities in the UAE, where it is targeted for local consumption and taken as bycatch (Jabado 2018). This species may also be impacted by habitat degradation due to coastal development, especially nursery grounds. Marine habitats in the 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.<em style=""font-family: Georgia; font-size: 12pt;""> 2010). Corals in the UAE and Arabian Gulf have severely declined due to the increasing frequency of mass bleaching events caused by rising water temperatures, which is a consequence of climate change, as well as pervasive coastal development (Riegl et al. 2018, Burt et al. 2019).

The Sharptooth Lemon Shark occurs in shallow inshore and offshore waters near the bottom and is often found on and around coral reefs and on sandy plateaus near coral at depths to at least 30 m (Stevens 1984, Compagno 1998). It is also known to occur around and within the mangrove forests in certain areas of the UAE (Abu Dhabi) and Sudan (Suakin), which may be used as nursery grounds (Bonfil 2003, R. W. Jabado pers. comm. 06/02/2017). The maximum size reported is 340 cm total length (TL) with size at maturity around 220 cm TL for males and females (Compagno et al. 2005). The gestation period is recorded at 10 to 11 months, a reproductive periodicity of two years with a litter size average of 9.3 (6 to 12) and size at birth of 60 cm TL. Growth rates are reported at 12.5 to 15.5 cm per year. The generation length is suspected to be around 16.5 years, similar to that of the Lemon Shark (Negaprion brevirostris), which reaches a similar maximum size (Brown and Gruber 1988).

Assessment rationale/justification
The Sharptooth Lemon Shark occurs throughout UAE inshore and offshore waters. In the UAE and neighboring countries, it is a minor component of shark landings, and may be relatively rarely occurring in the area. It is at risk from extensive fishing pressure by longline and gill net fisheries that operate throughout the Arabian Sea region. Extensive habitat degradation and loss due to coastal development in the Arabian Gulf region may also be impacting the species. 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.

Assessment rationale/justification
The Tawny Nurse Shark occurs throughout UAE coastal waters, and is presumably naturally uncommon there. This species is not targeted or valued in markets of the UAE. It is taken as bycatch in some areas of the Arabian Sea region (Sri Lanka and India), and declines have been noted. Slow life history characteristics, including low fecundity and a low annual rate of population increase causes the species to have 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.
