Black-Banded Sea Krait

Laticauda semifasciata

Laticauda semifasciata, also known as the Chinese Sea Krait or Black-Banded Sea Krait, is a species of venomous sea snake found in the coastal waters of the Pacific and Indian Oceans. This species has a distinctive banded pattern, with black and white or blue and white. 

They are medium-sized snakes, typically reaching around 1 meter (3-4 ft) in total length, with a laterally compressed tail which is used to propel themselves through the water, and sharp teeth for catching their prey.


Black-Banded Sea Kraits are found in the coastal waters of the Pacific and Indian Oceans, typically in the warmer waters, such as those around China, Philippines, Indonesia, and Palau. 

They can be found in a variety of marine habitats, including coral reefs, lagoons, and mangrove swamps, as well as estuaries and along sandy beaches. They are often seen in shallow water but can also be found at depths of up to 60m.

Chinese Sea Kraits are primarily fish-eaters. They primarily prey on small fish, but will also consume crustaceans, cephalopods, and other small marine animals.


Black-Banded Sea Kraits are primarily active at night and are known to be quite docile. They are good swimmers and use their laterally compressed tail to propel themselves through the water. 

They are also known to be able to stay underwater for extended periods of time, thanks to their ability to extract oxygen from the water. They are typically found alone or in small groups.


Black-Banded Sea Kraits belong to the genus Laticauda, and the scientific name for this species is Laticauda semifasciata. They belong to the Elapidae family, which also includes many other species of venomous snakes such as cobras and mambas.

The sea krait family, also known as Laticaudidae, is a small family of venomous sea snakes. It consists of a single genus, Laticauda, which includes 8 species.
