Bungarus andamanensis, the South Andaman krait, is a species of krait, a venomous elapid snake, which is found in the Andaman Islands of India. It was first described by Biswas and Sanyal in 1978.
The Andaman krait is a medium-sized snake, growing up to 1.3 meters in length. Its body is cylindrical, and the head is slightly broader than the neck. The eyes are small and entirely black with round pupils.
The body is glossy black or brownish, often with blue iridescence. It features 39–47 narrow yellow or white equidistant cross-bars on the body and 9–13 on the tail, with the bands widening toward the belly. The underside is yellowish-cream with irregular black or brown spots, and the tail often has distinct brownish spots. The lips are yellowish. Juveniles display vibrant yellow cross-bars and a distinct "^"-shaped marking near the head.
The Andaman krait is endemic to the Andaman Islands and Little Andaman Islands in India. It inhabits a variety of environments, including:
The species is frequently observed on roads after rains and has also been seen near termite mounds. It is extremely common in Little Andaman.
The Andaman krait is nocturnal and primarily active during and after rains. When alarmed, it slightly flattens its body, coils loosely while hiding its head, and may produce a squeaking sound. Juveniles are most often seen in June, suggesting a seasonal breeding pattern.
The species mainly preys on other snakes, including water snakes, and occasionally on fish. Adult specimens are rare and are typically found near freshwater streams.
Little is known about the breeding biology of this species, but the presence of juveniles in June indicates potential seasonal reproduction.
