Habitat and Ecology [top]

Habitat and Ecology:This species occurs in mangrove mudflats (Guinea et al. 1993). It has been seen crawling on consolidated mud out of water into a nearby crab burrow to forage (Guinea et al. 1993). It is preyed on by sharks (Lyle and Timms 1987). Can live in coastal areas disturbed by human development.

Threats [top]

Major Threat(s): There are no known major threats to this species, but development to associated habitat such as mangrove forests may be a concern.

Conservation Actions [top]

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

Sea snakes are protected in Australia since their addition to the "Listed Marine Species" by the Department of Environment and Water Resources in 2000. They are protected in Australia under the Environment Protection Biodiversity and Conservation Act 1999.

Conservation of mangrove areas is important for protection of this species.
