Brief Summary

provided by EOL authors

The dangerously venomous Banded Krait (Bungarus fasciatus) is widely distributed in Myanmar (Ayeyarwady Division, Kachin State, Magway Division, Mandalay Division, Rakhine State, Yangon Division) and from central and northeastern India through all of Southeast Asia including southern China, Thailand, Cambodia, Laos, Vietnam, and Malaysia to western Indonesia (Java, Sumatra, Kalimantan). In Myanmar, this species is found mainly in low-lying regionsat elevations from around sea level to around 300 m, although historical records suggest a range up to 2300 m. In Myanmar, most individuals encountered have been found in degraded habitat in the vicinity of villages and agriculture (including paddy). Several have been found in or along streams. Outside Myanmar, this species has been recorded from a wide range of habitat types. These snakes are active at night. (Leviton et al. 2003 and references therein. Masson (1930) reported a western extension of the then known range of B. fasciatus based on a specimen of about 5 feet seen on a road.

Yahya (1986) reported on a specimen he observed and photographed on 20 July1984 for more than an hour. He noted that its bright yellow and black bands were very conspicuous against the grassy background. When approached for photography, the snake would hiss, but did not strike. According to Yahya, the local people reported that this snake was a resident in the area (Nazramohamda, Darbhanga District, Bihar) and sometimes seen with young. Local people reportedly protect this snake as it is believed to bring prosperity to homes in its vicinity.It is also believed that other snakes do not reside in places where the Banded Krait resides.

Rundquist (1986) gave a brief account of what he believed to be the second captive hatching of this species in the United States (likely the result of a mating in the wild).

Dorsal scales in 15 longitudinal rows at midbody; subcaudal scutes undivided throughout; middorsal row of scales (vertebrals) strongly enlarged, as broad as or broader than long; tail end blunt. Distinct vertebral ridge down back formed by neural processes of vertebrae. Ventrals 200-234; subcaudals 23-39. Pattern of black and yellow bands, all of which encircle body. Total recorded length to 2125 mm, but over 1800 mm is said to be rare. (Leviton et al. 2003)

Banded krait

provided by wikipedia EN

The banded krait (Bungarus fasciatus) is a species of elapid snake found on the Indian Subcontinent and in Southeast Asia.[2] It is one of the largest kraits, with a maximum length up to 2.1 m (6 ft 11 in).[3]


The banded krait is easily identified by its alternate black and yellow crossbands, its triangular body cross section, and the marked vertebral ridge consisting of enlarged vertebral shields along its body. The head is broad and depressed. The eyes are black. It has arrowhead-like yellow markings on its otherwise black head and has yellow lips, lores, chin, and throat.[4]

The longest banded krait measured was 2.25 m (7 ft 5 in) long, but normally the length encountered is 1.8 m (5 ft 11 in).[3]

The snake has an entire anal plate and single subcaudals. The tail is small, about one-tenth the length of the snake.[5]

The scientific name of the genus is derived from the Kannada/Telugu word bangarum meaning "gold", referring to the yellow rings around its body.[4]

Distribution and habitat

The banded krait occurs in the whole of the Indo-Chinese subregion, the Malay peninsula and Indonesian archipelago, and southern China.[3] The species is common in the states of Mizoram, Assam and Tripura of India, Nepal and Bangladesh, but becomes progressively uncommon westwards in India.[4]

It has been recorded eastwards from central India through Bangladesh, Myanmar, Cambodia, Thailand, Laos, Vietnam, and southern China (including Hong Kong), Philippines to Malaysia and the main Indonesian islands of Borneo (Java and Sumatra), as well as Singapore.

In India, it has been recorded from Andhra Pradesh,[6] Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Maharashtra,[7] Northeast India, Odisha, Tamil Nadu, and West Bengal.[3] It has recently been recorded from Hassan District in Karnataka, and Chalkari, Bokaro District, Jharkhand and Trivandrum, Kerala.[8]

Banded kraits may be seen in a variety of habitats, ranging from forests to agricultural lands. They inhabit termite mounds and rodent holes close to water, and often live near human settlement, especially villages, because of their supply of rodents and water. They prefer the open plains of the countryside. The banded krait has been found in Myanmar up to an altitude of 5000 feet.[3]


Banded kraits are shy, not typically seen, and are mainly nocturnal. When harassed, they will usually hide their heads under their coils, and do not generally attempt to bite,[2] though at night they are much more active and widely considered to be more dangerous then.

During the day, they lie up in grass, pits, or drains. The snakes are lethargic and sluggish even under provocation. They are most commonly seen in the rains.[4]


The banded krait feeds mainly on other snakes, but is also known to eat fish, frogs, skinks, and snake eggs. Among the snakes taken by banded kraits are:[4] -

The prey is swallowed head first, after it has been rendered inactive by the venom.[4]

Breeding habits

Little is known of its breeding habits. In Myanmar, a female has been dug out while incubating a clutch of eight eggs, four of which hatched in May. Young have been recorded to measure 298 to 311 mm on hatching. The snake is believed to become adult in the third year of its life, at an approximate length of 914 mm.[10]


The venom of the banded krait mainly contains neurotoxins (pre- and postsynaptic neurotoxins) with LD50 values of 2.4 mg/kg[11]—3.6 mg/kg[12][13] SC, 1.289 mg/kg IV and 1.55 mg/kg IP.[12][13] The quantity of venom delivered averages out at 20–114 mg.[12] Engelmann and Obst (1981) list the venom yield at 114 mg (dry weight).[14] The major clinical effects caused by the venom of this species include vomiting, abdominal pain, diarrhoea, and dizziness. Severe envenomation can lead to respiratory failure and death may occur due to suffocation.[15]

A clinical toxicology study gives an untreated mortality rate of 1—10%, which may be because contact with humans is rare and when bites do occur, the rate of envenomation when biting defensively is thought to be very low.[2] Currently, polyvalent antivenoms is available in India and Indonesia.
