Quick Summary

Sea kraits are a group of highly venomous marine snakes belonging to the subfamily Laticaudinae, which are related to Asian cobras. Unlike true sea snakes, sea kraits are not as specialized for aquatic life. They have flattened tails but cylindrical bodies and can crawl and climb on land.1

Sea kraits are typically banded with black and white, blue, or yellow rings, and some species have a yellow snout. They are nocturnal hunters, primarily feeding on eels in shallow waters. While their venom is potent, they are not aggressive towards humans, and fatalities are rare due to their small venom output and short fangs. Sea kraits lay their eggs on land, often in limestone caves or rock crevices.1
