Bungarus fasciatus
(Banded Krait) is a wide-ranging, highly venomous elapid which on the Asian
mainland occurs in Bangladesh, Myanmar, southern China, northeastern India,
Bhutan, Nepal, Thailand, Cambodia, Laos, Vietnam, Peninsular Malaysia and
Singapore. Its range extends to the larger islands of western Indonesia
including Sumatra, Java, Borneo (including Brunei and eastern Malaysia) and
Bali.
With such a broad distribution, it seems possible that more than one species
is represented (Biakzuala et al, 2023).
Its body is triangular in cross-section. The head is small and of the same
width as the neck, and the eyes are small. The dorsum is white, pale yellow
or brownish with thick black crossbars of roughly equal width to the
intervening pale portions of the dorsum. The venter is pale.
This dangerous snake occurs in a range of lowland habitats including
woodlands, swamps and back mangrove. It has also been recorded in montane
forest up to 2500 metres elevation (Das, 2010).
Its diet comprises a variety of other vertebrates including rodents, other
snakes, lizards, frogs, fishes and reptile eggs (Das, 2010).
Bungarus fasciatus is typically nocturnal in habits; caution should
be taken during nocturnal rambles in areas where the species is likely to
occur. By day it is less likely to react to being disturbed. The powerful
neurotoxic venom of this snake can kill.
