About the Blue Krait

Bungarus candidus, commonly known as the Malayan krait or blue krait, is an extremely venomous species of snake. The blue krait is a member of the genus Bungarus and the family Elapidae. The Malayan krait may attain a total length of 108 cm (43 in), with a tail 16 cm (6.3 in) long.

Dorsally, it has a pattern of 27–34 dark-brown, black, or bluish-black crossbands on the body and tail, which are narrowed and rounded on the sides. The first crossband is continuous with the dark color of the head. The dark crossbands are separated by broad, yellowish-white interspaces, which may be spotted with black. Ventrally, it is uniformly white.

An unbanded black phenotype also occurs in some populations, reportedly in West and Central Java. The smooth dorsal scales are arranged in 15 rows, with the vertebral row much enlarged. The ventrals number 195–237; the anal plate is entire; and the single (undivided) subcaudals are 37–56 in number.

It is found in Southeast Asia from Indochina south to Java and Bali in Indonesia. In mice, the intravenous LD50 for this species is 0.1 mg/kg. Its mortality rate is 60–70% in untreated humans. The amount... Wikipedia →

Where does the Blue Krait sighting chance come from?

GBIF citizen-science records

It is estimated from how often the Blue Krait is recorded against all the reptiles logged in Cat Tien National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
