The Papuan black snake is found in Papua New Guinea, and has been recently found on Saibai Island in the Torres Strait. Its numbers are thought to be in decline, possibly as a result of the introduction of the cane toad (Bufo marinus) into its habitat. It lives in swampy areas of the southern coastal lowlands of PNG, where it feeds on small mammals and frogs. It is usually a uniform glossy black, but may be dark brown. It is solidly built, with a large, flat head. The length ranges from 2.1 to 2.4m. It is oviparous. The papuan black snake is said to be of a nervous disposition, avoiding human contact, but will strike aggressively if cornered.
