Brief Summary

Laticauda colubrina is a widespread, relatively abundant, and dangerously venomous sea krait ranging from the Andaman and Nicobar Islands and the Myanmar-Thai-Malaysian peninsula through the Indonesian archipelago to New Guinea and north to Palau, the Philippines, Taiwan, and the Ryukyu Islands, and southeastward along the island chain of the Solomon Islands, Vanuatu, Fiji, and Tonga. The yellow-banded sea krait clade is composed of the widespread L. colubrina plus  L. guineai (found in a small region of southern Papua New Guinea), L. saintgironsi (endemic to New Caledonia, where it is common), and L. frontalis (a dwarf species endemic to Vanuatu, where it is sympatric with L. colubrina). Members of the L. colubrina complex forage on reefs by searching underwater crevices while tongue-flicking, apparently identifying prey by smell; their diet consists almost exclusively of various kinds of eels. (Heatwole et al. 2005)

In Myanmar, occurs in coastal waters, tidal rivers, ashore (especially along rocky coasts). Reportedly not commonly encountered in “Indian and Indo-Chinese waters” although it is not uncommon around Singapore. Although rare in the Bay of Bengal, it is  possibly not uncommon along the Myanmar coast and west coast of the Malaysian Peninsula. This species also occurs in coastal waters of Thailand, Malaysia, and western Indonesia as far east as Polynesia and north along the east Asian coast and Philippines to southern Japan.  Individuals have been observed on a small uninhabited island around a mile off the Rakhine coast in the Bay of Bengal, where they were seen at rest during the day at low tide in rock crevices; surrounding waters were rich in large corals. In New Caledonia, these snakes are reportedly often found inshore under vegetation. They have been found at depths of greater than 60 m, but seem to prefer depths of less than 20 m. Laticauda colubrina are active both during the day and at night. (Leviton et al. 2003)
