Bungarus andamanensis

Bungarus andamanensis, commonly known as the South Andaman krait, is a venomous snake species endemic to the Andaman Islands of India. First described by Biswas and Sanyal in 1978, this elusive krait is distinguished by its glossy black or brownish body, often displaying blue iridescence, with narrow yellow or white cross-bars.

This species inhabits paddy fields, coastal bushes, mangroves, and freshwater streams, frequently appearing on roads after rainfall. It is nocturnal, primarily active during and after rains, and exhibits defensive behaviors such as flattening its body and coiling loosely while hiding its head.

The South Andaman krait is an ophiophagous predator, meaning it primarily preys on other snakes, including water snakes, and occasionally consumes fish. Juveniles are most commonly observed in June, suggesting a seasonal breeding pattern.

Although Bungarus andamanensis is classified as Near Threatened, little is known about its population trends and conservation needs. Its venom is highly potent, but detailed studies on its toxicity and medical significance remain limited.
