Laticauda is a genus of snakes from the subfamily Hydrophiinae. Laticauda species are the least adapted to sea life of all the members of Hydrophiinae; they retain the wide ventral scales typical of terrestrial snakes and have poorly developed tail fins. They are adapted to living on land and in shallow seas. These animals are also commonly known as sea kraits.


Members of the genus Laticauda can grow to 1.5 metres (4.9 ft) long.[1]


Laticauda species are found throughout the south and southeast Asian islands spreading from India in the west, north as far as Japan, and southeast to Fiji. They are mostly found in coastal waters.[2]


Laticauda species feed in the ocean, mostly eating moray and conger eels, and some squid, crabs, and fish. They have never been observed feeding on land.


Laticauda species are often active at night, which is when they prefer to hunt. Though they possess highly toxic venom, Laticauda snakes are usually shy and reclusive, and in New Caledonia, where they are called tricot rayé ("stripey sweater"), children play with them. Bites are extremely rare, but must be treated immediately.[3] Black-banded sea kraits, numbering in the hundreds, form hunting alliances with yellow goatfish and bluefin trevally, flushing potential prey from narrow crannies in a reef the same way some moray eels do.[4][5] Sea kraits are capable to of diving up to 80 meters in a single hunting trip.[6]


Laticauda females are oviparous, and they return to land to mate and lay eggs. Several males will form a mating ball around the female, twitching their bodies in what is termed "caudocephalic waves". Though these animals can occur in high densities in suitable locations, nests of eggs are very rarely encountered, suggesting specific nesting conditions need to be met.

Species and taxonomy

Eight species are currently recognised,[7][8]

The species L. schistorhynchus and L. semifasciata have been placed in the genus Pseudolaticauda by some authors.[9]

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Laticauda.


Sea snakes have thick parasites with occasionally heavy infections .[10]
