[2] The blue-lipped sea krait was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, where it was given the binomial name Coluber laticaudatus.

[2] The 19 rows of scales and the dark brown upper lip can be used to differentiate the blue-lipped sea krait from other Laticauda species.

[4] This species is found in the Indian and Western Pacific Oceans: Bay of Bengal (Bangladesh, East India, Andaman & Nicobar Islands, Sri Lanka, Myanmar, Thailand), coasts of Malay Peninsula to Indonesia, Timor-Leste, New Guinea, the Philippines, off the coasts of Fujian and Taiwan, Japan, Polynesia, Melanesia, Solomon Islands, New Caledonia, Palau, Vanuatu, Fiji, and Australia (Queensland).

[2][5] One specimen was found in Devonport, New Zealand in 2011 and again in January 2025, however it died shortly after being taken to Kelly Tarlton's Sea Life Aquarium.

Sea kraits forage in reefs and return to land to digest their prey, mate, slough, and lay their eggs.
