A small to medium-sized snake inhabiting primary and secondary forests, the Orange-necked Keelback preys mainly on frogs and toads. It thus frequents shallow streams and swampy areas. 

As its name implies, there is a thick orange band at the neck region, and the rest of the body is dark grey or black, with thin white banding.

This species ranges from Thailand and Peninsular Malaysia to Borneo (Kalimantan, Sarawak) and the Indonesian islands of Nias, Sumatra and Bangka. It is absent from Singapore.
