Individual black scales often occur on the white bands that connect to white belly. The head is grey-black the supralabials a big lighter. Like all kraits, it has smooth scales which are enlarged in the vertebral series. It inhabits forested areas up to 1,525 m. It is nocturnal and preys primarily on other snakes. Females produce 4-10 eggs per year; hatchlings are 27-29 cm. Venomous and potentially fatal. The Blue Krait occurs throughout Thailand, Peninsular Malaysia, Cambodia, Vietnam and parts of Indonesia.
