The yellow-lipped sea krait (Laticauda Colubrina) is a species of sea snake found in tropical Indo-Pacific ocean waters. The yellow-lipped sea krait is also known as the "banded sea krait" and the "colubrine sea krait".

Description[change | change source]

The yellow-lipped sea krait gets its name because of its yellow snout and yellow upper lip

Female yellow-lipped sea kraits are longer than males. Females can grow up to the length of 1.6 meters, while males grow up to the length of 1 meters. Yellow-lipped sea kraits are light or dark blueish-grey on the top and yellow underneath with black bands running down the body and tail. The upper lip and snout is yellow (hence its name) while the rest of the head is black. They are very venomous but they are not aggressive and rarely ever bite divers or swimmers.

Feeding[change | change source]

Yellow-lipped sea kraits are usually seen hunting for food in groups. Yellow-lipped sea kraits eat giant trevally, goatfish and their eggs. Yellow-lipped sea kraits also eat eels. The way they hunt is similar to the way moray eels hunt. They hunt by swimming into small holes and searching for prey.

Where they live[change | change source]

Yellow-lipped sea kraits can be found in the Indo-Pacific waters, mainly on coral reefs. But when yellow-lipped sea kraits need to mate they come on land.

Behavior[change | change source]

Yellow-lipped sea kraits are one of the most venomous snakes in the world, but they are not aggressive and rarely ever bite humans. Even though they live in water, Yellow-lipped sea krait do not have gills so they have to go to the surface to breath air, but a yellow-lipped sea krait can go as deep as 100 meters underwater and stay there for up to an hour. Every 10–14 days yellow-lipped sea kraits come on land to digest their food, to shed their skin or mate and lay their eggs. They lay around 5-13 eggs at a time.

Venom[change | change source]

When something is bitten by a yellow-lipped sea krait, the venom affects the muscles and the nerves. The venom of a yellow-lipped sea krait is said to be 10 times more deadly than the venom of a rattlesnake. In a single bite, a yellow-lipped sea krait can give more than 12 times the venom needed to kill a human. They don't recognize humans as prey or predator so they avoid swimmers and divers and rarely bite them.
