This is a widespread species within the eastern United Arab Emirates, found on harder surfaces from Sham in northern Ras Al Khaimah to Ghantoot (Gardner 2013, Burriel-Carranza et al. in press). Inland, it is found around the base of the mountains such as Jebel Faiyah, Qarn Nazwa and Jebel Hafeet. It also occurs along the eastern coast from Khor Kalba to Khor Fakkan, and on the interdunal plain near Um as Zumul. It occurs from sea level to 400 m asl.This lowland species is endemic to the Arabian Peninsula, from Ras Ghanada in the United Arab Emirates through Oman to southeastern Yemen (Metallinou et al. 2014).

Within the United Arab Emirates, the species is widely distributed throughout the Hajar Mountains, from the north at the Musandam Peninsula border to the Oman border in the south (Gardner 2013, Burriel-Carranza et al. in press). It occurs from sea level to at least 1,400 m asl. Globally, the species is endemic to the Hajar Mountains of Oman and the United Arab Emirates (Gardner 2013).

Within the United Arab Emirates, this species occurs inland from Sharjah south to Abu Dhabi inwards to Al Ain (Gardner 2013) from sea level to 300 m asl, with an isolated record also known from the vicinity of Khor Fakkan on the east coast (Böhme and Leptien 1990, Gardner 2013, Burriel-Carranza et al. in press).Globally, the species is endemic to the Arabian Peninsula, where it has been recorded from the United Arab Emirates, Oman (including Masirah Island) and eastern Yemen (Arnold 1977, 1980; Carranza et al. 2018). There is a questionable record from the northern Empty Quarter in Saudi Arabia. It is very localised in Yemen, where only one record is known.

Within the United Arab Emirates, this species has only been found in the gravel outwash of Wadi Agran, within a few hundred meters of the Oman border (Gardner 2013, Burriel-Carranza et al. in press). It occurs from 300-400 m asl. The species has marginal occurrence with the UAE.This species is endemic to the southern Arabian Peninsula, where it ranges from northwestern Oman (Ibri area) and Dibab (on the Gulf of Oman coast) southwards, via Masirah Island, to Dhofar, where it is common (Carranza et al. 2018). A disjunct population occurs in north Yemen, where it is known from two records (Arnold 1980, 1986).

Within the United Arab Emirates, the species occurs throughout the Hajar Mountains from sea level to 600 m asl (Gardner 2013, Burriel-Carranza et al. in press). Globally, the species is endemic to the central and western Hajar Mountains, ranging from the Musandam Peninsula in Oman through the United Arab Emirates to Jebel Akhdar in Oman (Gardner 2013, Carranza et al. 2018). It has been found from sea level up to 1,700 m asl.

Within the United Arab Emirates, this species occurs throughout the Hajar Mountains (Babocsay 2004, Gardner 2013, Burriel-Carranza et al. in press) from sea level to 1,000 m asl. The species also occurs in Jebel Hafeet near Al Ain.This species is endemic to the Hajar Mountain of Oman and the United Arab Emirates (Egan 2007). The animals are seldom found above 800 m asl.

In the United Arab Emirates, this species has been recorded from the Sila area through the coastal deserts of Abu Dhabi to Ras Al Khaimah, and further inland around Sweihan and Al Ain (Gardner 2013, Burriel-Carranza et al. in press). The species has also been recorded along the east coast of the United Arab Emirates but is absent from the Hajar Mountains. The species is found from sea level to 400 m asl.This species is present in Saudi Arabia, Oman, Yemen, United Arab Emirates, Qatar, Bahrain and Kuwait.

Within the United Arab Emirates, this species is localised and uncommon in widely scattered localities in the Abu Dhabi Emirate (Gardner 2013, Burriel-Carranza et al. in press). It occurs from sea level to 200 m asl. The species is endemic to the Arabian Peninsula (Haas 1957, Salvador 1982), where it is also found in central Oman and northern and eastern Saudi Arabia, around Dhahran and Sakaka (Leviton et al. 1992, Carranza et al. 2018).

This species is confirmed in United Arab Emirate waters (Soorae et al. 2006, Egan 2007, Gardner 2013, Buzás et al. 2018), with confirmed records from the Arabian Gulf (from small numbers of strandings) and the Gulf of Oman, where it is found up to 5.9-6.2 km offshore (Géczy et al. 2017, Buzás et al. 2018). The depth range is not certain, but likely to be found to c.55 m depth along the east coast. Museum records are available for the UAE in the Al Mayya Sanctuary, Fujairah.Globally, the species is found in the Arabian and Oman Gulfs, east to Indonesia, the Gulf of Papua and China (Culotta and Pickwell 1993, Heatwole 1999). Its range includes Hong Kong in the east and Australia to the south (Kharin 2004).

Presence of this species is confirmed within the United Arab Emirates marine territorial waters (Soorae et al. 2006, 2010; Gardner 2013, Castilla et al. 2017, Buzás et al. 2018). It is most common in the southern part of the east coast, south of Fujairah city, from 3.5 - 7 km offshore (Géczy et al. 2017, Buzás et al. 2018). In the Arabian Gulf, this species is apparently less common, with few known records; Soorae et al. (2006) recorded the species from Abu Dhabi island. It has been recorded from Iranian waters in the northern Arabian Gulf, with records from the Straits of Hormuz requiring confirmation. The depth range is not certain, but likely to be found to c. 55 m depth along the east coast. The first museum specimen from the region was collected off the west coast of the Musandam Peninsula (Arabian Gulf, UAE) in 1931 (Gasperetii 1988), and recent museum records are available for the UAE (Al Mayya Sanctuary, Fujairah, United Arab Emirates).Globally (Culotta and Pickwell 1993, Lukoschek et al. 2010), this species has one of the most extensive distributions of all sea snakes (Minton 1975, David and Ineich 1999). It occurs from the Arabian Gulf to eastern Australia and includes Pakistan, the entire Indian coastline, Myanmar, Thailand, South China Sea, Malaysia, the Philippines, Indonesia, Papua New Guinea and northern Australia (David and Ineich 1999; Ukuwela et al. 2014, 2016). One individual of this species has been reported from an unknown location in New Caledonia (Rasmussen and Ineich 2000), but it is not clear whether there are breeding populations in that region.
