Aipysurus tenuis Lönnberg & Andersson, 1913:13
Arafura sea snake, Brown-lined sea snake, Mjoberg's seasnake
Taxonomy & Nomenclature
Synonym/s: Oceanius tenuis Lönnberg & Andersson, 1913:13
According to (Rasmussen, 2001) the Arafura sea snake (Aipysurus tenuis) is the most distinct taxon of the genus Aipysurus because it is the only species to exhibit more than 180 ventral scales.
Last record: 1970
IUCN RedList status: Data Deficient
According to (Rasmussen, 2001) the Arafura sea snake (Aipysurus tenuis) is the most distinct taxon of the genus Aipysurus because it is the only species to exhibit more than 180 ventral scales. It is therefore unlikely that this species could be confused with its congeners, and hence misidentification of specimens thought to belong to other species in the genus cannot plausibly account for a lack of recent sightings. Its extinction must therefore be considered a real possibility giving a complete lack of sightings since 1970.
Arafura Sea (Dampier to Broome?), Western Australia, Australia
