Taxonomic notes and synonyms listed
A recent molecular phylogenetic study of 39 sea snake species in 15 genera recovered Hydrophis as broadly paraphyletic with respect to several other genera (Sanders et al. 2013). Instead of erecting multiple new genera, the authors recommended dismantling the mostly monotypic genera Pelamis, Enhydrina, Astrotia, Thalassophina, Acalyptophis, Kerilia, Lapemis and Disteira, and recognizing a single genus, Hydrophis, for these taxa (Sanders et al. 2013). This classification system avoids confusion and better reflects the history of recent and very rapid diversification of these snakes and are followed by most recent authors.There are three forms of this species (Smith 1926).

Assessment rationale/justification
This species is known from adjacent areas of both the Gulf of Oman and the Arabian Gulf, however, there are no confirmed records from the territorial waters of the UAE. The species is considered Not Applicable at present for the UAE national Red List, and surveys are needed to confirm the occurrence of the species in the UAE.

Taxon distribution as listed in assessment
This species has been reported as present within the United Arab Emirates marine territorial waters (Gasperetti 1988, Soorae et al. 2006, Egan 2007, Castilla et al. 2017), however, there are no known confirmed records from UAE waters in the Arabian Gulf. There is a single known museum specimen collected in UAE waters, from near Sir Abu Nu'ayr (Arabian Gulf, Emirate of Abu Dhabi, UAE) by the crew of the HMS Dalrymple (British Royal Navy) around 1963 (Gasperetti 1988), however, the identity of this record requires confirmation. It is possible that the species occurs only in the northern parts of the Arabian Gulf, but Rezaie-Atagholipour et al. (2016) reported no records from Iranian waters. There are no records from the east coast of the UAE (Géczy et al. 2017, Buzás et al. 2018), although the species is recorded from adjacent waters near Muscat in Oman (Rezaie-Atagholipour et al. 2016). The first museum specimen from the region was collected in Muscat, Oman by A.S.G. Jayakar and is the type specimen of the Hydrophis jayakari (Boulenger, 1887), a synonym of H. viperinus.Globally, this species is known from the Arabian Gulf of Pakistan, around India and Sri Lanka, south to Indonesia (including Borneo) and east to Bangladesh, southeast Asia and southern China (Culotta and Pickwell 1993, Heatwole 1999). There are no records from the Philippines (Rasmussen et al. 2010).

Habitat details as listed in assessment
There are no confirmed records from UAE waters.Globally, the species generally occurs in slightly deeper waters (15 - 30 m) in muddy soft bottom habitats (Rasmussen et al. 2010). The maximum size is approximately 97 cm TL (captured in a trawl in Goa, India; Rasmussen et al. 2010). Feeds on spiny flatheads in India (Rasmussen et al. 2010) and on eels and gobies (Voris and Voris 1983). An average of 3-4 large young and high reproductive effort (Lemen and Voris 1981).
