This is a widespread species and is common in some parts of the range. It lives on soft bottom habitats. It is captured in trawl fisheries, but this is not thought to be a major threat and hence it is listed as Least Concern.

Population [top]

Population:This species was relatively common (as trawler bycatch) in Malaysia in 1989 (Stuebing and Voris 1989). It also appears to be a common sea snake in Pakistan (Minton 1966). Along with Enhydrina schistosa and Lapemis curtus it is probably the most common species in the waters of the Indian sub-continent. It is far more common on the east coast than the west coast of the sub-continent (A. Lobo pers. comm. 2009). On the Coromandel coast (east India), 975 individuals were captured between 2003-2004, and was considered the most common sea snake in the region (Karthikeyan et al. 2008).
Current Population Trend:Unknown

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species can be found in shallow seas over muddy bottom (Stuebing and Voris 1989). It feeds mostly on eels (Voris and Voris 1983, Das 2007), but also gobies and marine invertebtrates (Das 2007).

Ten specimens were collected from trawl nets in Pelabuhanratu Bay on the south coast of West Java ~5-10 km from shore at depths of 20-30 m in turbid water over sandy bottoms. All of the six adult females collected were gravid, with 1-10 embryos of ~35-43 cm total length (K. Sanders and Mumpuni pers. obs. April 2009). In Pakistan specimens were collected in shallow, muddy, mangrove swamps during the monsoon season (Minton 1966).

Threats [top]

Major Threat(s): This species is commonly caught as bycatch by trawlers in many parts of its range: Malaysian Borneo (Stuebing and Voris 1989, Das 2007); southern coast of Java (K. Sanders and Mumpuni pers. obs. 2009); east coast of India (Karthikeyan et al. 2008, A. Lobo pers. comm. 2009).

Conservation Actions [top]

Conservation Actions: There are no species specific conservation measures for this species, but it may occur in marine protected areas.

No sea snake species is currently listed by CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora).
