Overview
The brown-lipped sea krait is a common and widely distributed amphibious sea snake found across coral reef habitats of the tropical Indo-Pacific. It is closely related to other Laticauda kraits and shares their habit of moving between sea and land.
It carries potent venom used to hunt eels, but bites on humans are rare, as the species is generally calm and non-aggressive.
How to identify it
- Bold blue-gray to black bands alternating with pale bluish or cream interspaces
- Dark brown to blackish upper lip, distinguishing it from the yellow-lipped sea krait
- Yellowish snout tip
- Cylindrical body with a paddle-shaped tail
- Adults typically 0.8-1.4 m
Habitat & range
Inhabits coral reefs, rocky shorelines, and adjacent coastal waters throughout the tropical Indo-Pacific, from the eastern Indian Ocean through Southeast Asia to the western Pacific islands, coming ashore onto rocky or vegetated islets.
Behavior, diet & reproduction
Feeds primarily on eels, hunting within reef crevices and returning to land to rest and digest. Oviparous, laying eggs on land rather than bearing live young. Generally docile and slow to bite even when disturbed.
