Assessment rationale/justification
The Spinner Shark occurs throughout UAE inshore and offshore waters. Little specific data are available for this species in the UAE. 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. Both juveniles and adults are valued for meat and fins. 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.

Habitat details as listed in assessment
The Spinner Shark occurs in inshore and offshore waters on continental and insular shelves to depths of 75-100 m (Jabado and Ebert 2015). It is most common shallower than 30 m and also occurs in bays and off river mouths. It attains a maximum size of about 283 cm total length (TL). Males mature at ~177 cm TL, females mature at around 159 cm TL (Jabado and Ebert 2015). The species has an 11-15 month gestation period and is placentally viviparous, producing 3-20 pups (usually 7-11) with a size at birth of 48-55 cm TL. The reproductive cycle is two years (Castro 1993). There are no age data from the region, but generation length is suspected to be around 13 years based on work in South Africa (Allen and Wintner 2002) suggesting maturity at about 9 years and maximum age at about 17 years. In the Tasman Sea, age at maturity for females and males was 10.1 and 8.5 years, respectively (Geraghty et al. 2015).
Threats listed in assessment
Information pertaining to threats specific to the UAE are unavailable. This species is impacted by target (for fins and their valuable meat) and bycatch fisheries that are active elsewhere in its range. Marine habitats in the Arabian 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. 2010).

Assessment rationale/justification
The Pigeye Shark occurs throughout UAE inshore and offshore waters. It is likely to have often been confused with the Bull Shark (Carcharhinus leucas), which causes difficulty when interpreting landings data. Little specific data are available for this species in the UAE. 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 and longline fisheries that operate within its range outside and surrounding UAE waters. In addition, degradation of rivers and estuaries in the Arabian Gulf region is likely a significant threat, particularly to juveniles. 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 65 years. It is listed as Vulnerable A2cd.

Habitat details as listed in assessment
The Pigeye Shark occurs in inshore and offshore waters to depths of at least 100 m and juveniles are known to occur in estuaries (Ebert et al. 2013). Data on the life history of this species in the region is limited. Maximum reported size is 303 cm TL (Henderson et al. 2004). Size at birth is 57-72 cm TL, males mature at 195-227 cm TL, females mature at less than 195-224 cm TL (Moore et al. 2012, Ebert et al. 2013). Litter sizes reported include 11 from the Red Sea (I. Elhassan unpubl. data). In other parts of the range, litter sizes range from 3-13 (Bass et al. 1973). In Australia, females mature at 13 years and live to more than 30 years, while males mature at 12 years and live to more than 26 years (Tillett et al. 2011). Based on these data, generation length is estimated at 21.5 years.

Assessment rationale/justification
The Blacktip Shark commonly occurs throughout UAE inshore and offshore waters. It is frequently taken in a wide range of artisanal and commercial fisheries, and is one of the dominant shark species valued for its meat and fins at many landings sites across the Arabian Sea region. Although there are limited data on its status, other Carcharhinus species in the Arabian Gulf have undergone significant declines due to exploitation. It has a relatively low reproductive capacity, which causes it to be susceptible to over-exploitation. 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.

Habitat details as listed in assessment
The Blacktip Shark occurs in coastal waters on continental and insular shelves and occasionally offshore to depths of at least 100 m. Size at birth is 38-72 cm total length (TL) (Ebert et al. 2013). Maximum length is 287 cm TL. Females mature about 155-164 cm TL and males from about 143 cm TL (Sudan) to 184 cm TL (UAE) (Jabado et al. 2015; I. Elhassan unpubl. data). Size at birth is 38-72 cm TL (Ebert et al. 2013) with litter sizes from 4-11, with most about 8 (I. Elhassan unpubl. data). There is no ageing data from the region, but information from Indonesia, where maximum size is similar to that recorded from the Arabian Seas region, suggests that maturity occurs at about 8 years and maximum age is about 17 years with a generation length estimated at 13 years (Smart et al. 2015).
Threats listed in assessment
Information pertaining to threats specific to the UAE are unavailable. This species is impacted by target (for fins and their valuable meat) and bycatch fisheries that are active elsewhere in its range. Inshore fisheries are generally intensive throughout the Arabian Sea region, and in some areas, fishing effort is increasing. 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. 2010).

Assessment rationale/justification
In the United Arab Emirates, this subspecies is found in the south and west of the Abu Dhabi Emirate. The extent of occurrence (EOO) is moderately large, approaching 45,375 km<sup>2</sup>, however, the area of occupancy (AOO) is restricted, at just 324 km<sup>2</sup>. Its primary habitat, sandy or gravel plains, is impacted by a range of threats such as urban development, oil and gas exploitation, etc, which may result in local extirpations. As a result, the subspecies is assessed as Vulnerable (VU A2abcd+4abcd) based on observed and inferred (declines in AOO and habitat quality, and levels of exploitation) population decline in the past and ongoing that exceeds 30%. The population is suspected to have undergone a decline of at least 30% in the previous three generations (30 years) as a result of habitat loss, and a future decline of at least 10% is suspected as a result of ongoing habitat loss. The subspecies faces a wide range of threats in addition to urban development, including loss of vegetation cover, and persecution. The subspecies is unlikely to be declining fast enough for this subspecies to qualify for listing in a more threatened category and viable populations are present in several Protected Areas. This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations outside the UAE is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012).Conservation actions are required for this subspecies. Education is required to ensure that the existing Federal Law of the United Arab Emirates that prohibits the hunting, collection, and disturbance of the species is implemented, and habitat protected. Further research is required, including habitat and population monitoring.

Habitat details as listed in assessment
This subspecies is found in sandy or gravel plains, interdunal plains and flat wadi beds with scattered vegetation (Gardner 2013). They are more frequently encountered on cemented sandstone or on hard surface plains, and dependent on vegetation cover. A ground-dwelling and diurnal subspecies. They prefer high temperatures and are most active during summer, while on cool winter days they may not leave the burrows at all (Gardner 2013). Adults are vegetarian and are able to survive on poor quality forage (Gardner 2013). They feed on a broad range of plants, including grasses and herbs, but tend to avoid Tetraena qatarense despite its abundance (Gardner 2013). Individual lizards may move between several non-exclusive burrows (Gardner 2013). Mating occurs from spring to summer, and females lay a clutch of 12-30 eggs in the burrow.
Threats listed in assessment
Although a widespread the subspecies, it is not evenly distributed over its range, being dependent on sandy or gravel plains for its burrows, and generally avoiding soft sand or dunes (Gardner 2013). As a result, it makes the subspecies vulnerable to threats such as urban development, road construction, oil and gas exploitation etc, which may result in local extirpations. Over-grazing on the plains leads to the loss of vegetation cover, whilst tree-planting impacts the subspecies elsewhere. The subspecies is also subject to persecution.The combination of extended drought duration and over-grazing (even in protected areas), leading to the loss of essential vegetation cover, is hard to estimate but may be significant.

Assessment rationale/justification
Uromastyx aegyptia ssp. leptieni relatively widespread in the United Arab Emirates, however, the area of occupancy (AOO) is moderately restricted, at 564 km<sup>2</sup>. The taxon is listed as Vulnerable (VU A2abcd+4abcd) due to continued urban development in its range which has resulted in a decline in suitable habitat (and AOO), and in view that the subspecies is regionally endemic. The population is suspected to have undergone a decline of at least 30% in the previous three generations (30 years) as a result of habitat loss, and a future decline of at least 10% is suspected as a result of ongoing habitat loss. The subspecies faces a wide range of threats in addition to urban development, including loss of vegetation cover, and persecution.The subspecies is unlikely to be declining fast enough and viable populations are present in several protected areas, thus the subspecies does not qualify for listing in a more threatened category.

The eggs incubation period is 59-65 days.
Threats listed in assessment
The major threat to the subspecies is habitat loss through residential and industrial development and road construction. It is uncertain to what extent the taxon is harvested from the wild for either the pet trade or human consumption or medicinal use. Recreational off-road driving may have a negative impact on the subspecies in certain areas. Over-grazing on the plains leads to the loss of vegetation cover, whilst tree-planting impacts the subspecies elsewhere. The subspecies is also subject to persecution.The combination of extended drought duration and over-grazing (even in protected areas), leading to the loss of essential vegetation cover, is hard to estimate, but may be significant.

Assessment rationale/justification
Within the United Arab Emirates, the species is currently only known from the Wadi Al Helo area. The species is listed as Vulnerable (VU D2) due to its small area of occupancy (AOO) and extent of occurrence (EOO) of 4 km<sup>2</sup>. This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations outside the UAE is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012). Despite occurring at low densities, the population appears stable at present. There are potential threats from infrastructure development, that could significantly impact the population size of the species.The species is new to science with the possibility that more populations may be discovered in similar habitat in the future. The species should be reassessed if new data become available.

Taxonomic notes and synonyms listed
This species was described in 1834 as Coluber ventromaculatus (Smith 1943). The type locality is unknown. This species is included in Platyceps following Nagy et al. (2004). Western populations of Platyceps ventromaculatus differ from populations in South Asia (India and Pakistan) for which the name Coluber chesneii Martin, 1838 is available. Schätti et al. (2012) determined that C. chesneii represents a subspecies of Platyceps karelini, removing these populations from P. ventromaculatus.Khan and Khan (2000) didn't specify any neotype for their new subspecies which are based on a figure in Gray (1830). The status of these subspecies, therefore, remains uncertain (no holotype specified, no valid description after ICZN) (Uetz et al. 2018). Barabanov (2003) indicated that the name C. v. bengalensis is not available and suggested the replacement name C. v. khanorum. Coluber ventromaculatus Gray, 1834 is the type species of the genus Platyceps Blyth, 1860. Its occurrence in the Himalayan foothills (Himachal Pradesh, Uttaranchal) and the speciï¬c identity of the holotype of P. semifasciatus Blyth, 1860 needs further investigation. P. ventromaculatus crosses the Indus Valley and is found, for instance, along the Makran littoral to as far west as the border area with Iran. Coluber chesneii Martin, 1838 may be a valid northern Saharo-Arabian taxon of the genus Platyceps Blyth, 1860 (Schätti and Schmitz 2006).

Assessment rationale/justification
Within the United Arab Emirates, this species is only recorded from two coastal islands, Sir Bani Yas and Dalma. The origin of the species in the UAE requires confirmation, however it is presumed to be native in this assessment.Little is known of the population size or trend of this species, however, given the restricted area involved, a population size of less than 1,000 mature individuals is presumed. As a result, the species is assessed as Vulnerable (D1). This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations outside the UAE is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012).Further research into the origin of the species in the UAE and its population size and trend is needed.

Taxon distribution as listed in assessment
Within the United Arab Emirates, this species is only recorded from Sir Bani Yas and Dalma islands (Aspinal and Gardner 2007, Burriel-Carranza et al. in press), from sea level to 100 m asl. The species is probably native to the UAE, and it is found in adjacent parts of Qatar for example. Further research is required to confirm the origin of this species in the UAE; it may have been introduced, or it could be a glacial relict for example. Presence on other islands is not known, but further surveys are needed.The species is widespread globally, from the northern Arabian Gulf region (in southeastern Iraq, Kuwait, Bahrain, eastern Saudi Arabia, Qatar, United Arab Emirates, and southeast Iran), east to Pakistan, although the eastern extent requires confirmation.

Habitat details as listed in assessment
In the UAE, this species is found under rocks and in crevices of rocks, climbs into trees. Found in planted woodlands on Sir Bani Yas.This is a diurnal, semi-desert or sandy desert species known to sometimes hide under rocks and in crevices of rocks, generally found in steppe habitat with sparse vegetation. It can be found in forests on alluvial soils, but avoids more humid situations along watercourses (Khan 2006). It can be encountered in date groves, farm buildings, agricultural land and rubbish dumps (Egan 2007).
Threats listed in assessment
Threats to this species include urbanization and general development, however, these are localized within its range. The species will be killed when found, and in the past, a bounty encouraged control.

Assessment rationale/justification
Within the United Arab Emirates, this species is currently known from a single location, Khor Kalba in the Emirate of Sharjah. The species has an extensive distribution on the Batinah coastal plain of Oman. Significant past threats have ceased since the designation of most of its range in the UAE as a protected area, however, the threats would immediately return if the designation was removed, or if management became inadequate. The species has a very restricted area of occupancy (AOO) and extent of occurrence (EOO) and it is limited to a single locality within the United Arab Emirates which makes it prone to effects of human activities.The species is listed as Vulnerable (D1) due to the population size, which is suspected to be much less than 1,000 mature individuals. This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations outside the UAE is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012).

Taxon distribution as listed in assessment
Within the United Arab Emirates, this species was reported from the United Arab Emirates for the first time by Gardner (2005), where it is so far known only from Khor Kalba in the Emirate of Sharjah (Burriel-Carranza et al. in press). It occurs from sea level to 100 m asl in a single location.Globally, this species ranges from southeastern Iran (Sistan and Baluchistan, and Kerman provinces to southwestern Pakistan (western Baluchistan and along the Makran coast; Khan 2006), southern Afghanistan and the northern coast of Oman (Batinah region) (Anderson 1999, Carranza et al. 2018). It is found from around sea level to 1,400 m asl. In Oman, this lizard is confined to low-lying coastal areas, where it is known from fewer than ten localities over an area of around 14,450 km<sup>2</sup>.

Habitat details as listed in assessment
The species is found on sandy coastal plains and low dunes with sparse vegetation (Gardner 2013). It is a diurnal species that preys on invertebrates. Sexual maturity is reached in one year and the breeding season is during spring and summer (Gardner 2013). Burrows are mostly located near vegetation.
Threats listed in assessment
Within the UAE, the habitat of this species at Khor Kalba is now improving since designation as a protected area. Prior to that, threats included recreational activities, fisheries activities (with the beach used for access and for fish-drying), and recreational driving on the dunes and beach, which had significant impacts on the species.There are no major threats to this widespread and adaptable species globally. In Oman, where the species is localized and confined to coastal areas, it is likely to be at high risk from coastal development, for example around Muscat. Some known sub-populations may already have been lost.

Taxonomic notes and synonyms listed
Hemidactylus persicus was described by Anderson in 1872 based on specimens collected from Shiraz, Iran; its type locality is restricted to Shiraz (Smith 1935). Morphologically typical animals occur in northeast Saudi Arabia (as far south as Al-Hofuf and perhaps ar-Riyadh), in Bahrain, Kuwait, and lowland Iraq, southern Iran, Pakistan and Gujarat (India) (Smith 1935, Anderson 1999, Minton Jr. 1966, Leviton et al. 1992, Vyas et al. 2006, Sindaco and Jeremäenko 2008). They are characterized by relatively small size (up to 67 mm SVL), a low number of lamellae under the 1st toe of pes (mean 8.8, 8-“9) and relatively numerous prenatal pores in males (mean 9.2, 8-“11) arranged in a V-shaped line in front of the vent (Carranza and Arnold 2012).

Assessment rationale/justification
Within the United Arab Emirates, this species is known from Qarn Nazwa, the Dubai city area (where it is considered to be introduced), and from two offshore islands (Dalma and Sir Bani Yas). The species has a restricted extent of occurrence (EOO) and area of occupancy (AOO), however, the population trend at present, based on the Qarn Nazwa locality, is presumed to be stable. At Qarn Nazwa, it is thought likely that there are fewer than 1,000 mature individuals, whilst the populations on the islands, if native, are small. As a result, the species is assessed as Vulnerable (VU D1) on the basis of the restricted number of mature individuals. This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations outside the UAE is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012).Further research into the distribution and origin of the species in the UAE is required, and monitoring of the population at Qarn Nazwa is essential.

Taxon distribution as listed in assessment
Within the United Arab Emirates, this species is known from Qarn Nazwa and two of the islands (Dalma and Sir Bani Yas; Gardner 2013, Burriel-Carranza et al. in press), and from recent records of the species within the Dubai city area, which are presumed to be introduced. It is found from sea level to 200 m asl. Whilst the origin of this species in the UAE requires confirmation, the species was first found at Qarn Nazwa prior to widespread development that led to species introductions, and it is considered to be native to UAE at present.The global distribution of this species ranges from the Arabian Peninsula to Iraq, southern Iran (Khuzestan, Fars, Kerman and Balochistan Provinces) and Pakistan (Sind and Waziristan) (Minton 1966, Anderson 1999). It exhibits a marginal occurrence in India, where it has recently been reported from Jessore, Gujarat (Vyas et al. 2006). It is found from lowland areas to around 1,000 m asl (Minton 1966). It has been reported from northwestern Oman, close to the border with the UAE (Carranza et al. 2018).

Habitat details as listed in assessment
This species naturally inhabits rocky areas in arid regions (Qarn Nazwa population), including those in limestone outcrops where it clings to cliffs, boulders and bushes (Gardner 2013). Apparently not a house gecko in Arabia, though it has occasionally been found in houses (Gardner 2013). It is nocturnal and females lay two hard-shelled eggs glued to rock surfaces or in secure crevices.
Threats listed in assessment
There appear to be no major threats to this species at Qarn Nazwa, where it occurs within a protected area. The island populations need further research.
