Laticauda Colubrina is also called as banded sea krait or yellow lipped sea krait due to having a yellow upper lip in which the color yellow extends throughout the eyes and side of the head. The snake has a smooth, scaled black-striped cylindrical body with a shade of bluish-gray and a yellowish belly. Similar to other kraits, it also has a  flattened body, nostrils closed to the sides of its snout, and a paddle-shaped tail that enhances their swimming capability. 

The tail and the head of this snake are also seen to be similar in which it protects and helps them to fool its predator. According to some researches, these kinds of traits can help them to develop their defense strategy when they are searching for their prey. They are described as a cobra living in the water because of their strength and venom.

Where it is Seen?

Banded sea kraits are typically found along the coast side of the eastern Indian and western Pacific oceans. The distribution of these snakes is found to the coastal waters of southeast Asia, Sri Lanka, Japan, New Guinea, And the Philippines.


Banded sea kraits usually inhabit through warm, shallow seas along the coral reefs and mangroves where their prey usually resides.

In addition, these snakes usually spend their lives in the depths of the ocean, while half of the percent they like to spend their life on rocky shores in order for them to digest shed their skin, court, mate, and lay eggs. 

Behavior and Temperament

Most of the activity of these snakes usually happens at night, but they are not identified as any other snakes as nocturnal because their activities at night are not frequent. At day time, they often go to the land in order to be exposed to warmth and light; that is why they could often be seen by humans. This kind of snake species find their prey underwaters, but they go to the land in order to rest, digest, and reproduce. 

Banded sea kraits have neurotoxic venom wherein they use it for hunting their prey. In addition, this snake’s venom is said to be ten times more potent and could be caused paralysis, hypertension, and even death, but they are characterized as nonaggressive snakes, and they only attack once they were being cornered and threatened by the humans. Despite having a powerful venom, they usually preyed upon large varieties of fishes such as sharks, and birds like sea eagles. Hence, the similarities of their heads and their tail can help them fool these predators sometimes. 

They also have the tendency to play dead if a predator tends to grab them, so if humans see that this snake is just lying on the ground not moving, don’t pick it up immediately because if they are just playing dead, they might aggressively bite you with their poison. If it so happens that you see them in the corals while having snorkeling or scuba diving, just don’t go near them because they might perceive you as their predator.


The primary food of the banded sea kraits are eels, but they also feed on small fishes such as gobies. They catch and paralyze their prey through their powerful venom and swallow them whole. Furthermore, these snakes tend to exhibit different behaviors in hunting due to their sexes. Males tend to hunt smaller eels, which is only found in shallow water where they can only survive, while females hunt larger eels, which is usually found in much deeper water.

Males chase the larger, slower females and entwine around her. The males rhythmically contract to produce what are called caudocephalic waves. The duration of their copulation takes about two hours, but the mass of snakes may remain entwined for several days. Females deposit up to 10 eggs in a crevice on the land.
