Pseudechis is a genus of venomous snakes in the family Elapidae. It contains the group of elapid species commonly referred to as the black snakes. Species of Pseudechis are found in every Australian state with the exception of Tasmania, and some species are found in Papua New Guinea. They inhabit a variety of habitat types, from arid areas to swampland. All species are dangerous (Pseudechis signifying "like a viper", Greek echis) and can inflict a potentially lethal bite. Most snakes in this genus reach about 2 m (6.6 ft) in total length (including tail), and vary in colour. Some species are brown, whereas others are black. The most recognisable and widespread species in the genus are the red-bellied black snake (P. porphyriacus) and the king brown snake (P. australis). These snakes feed on lizards, frogs, birds, small mammals, and even other snakes. All species of Pseudechis lay eggs with the exception of the red-bellied black snake P. porphyriacus which is viviparous. The genus Pailsus is a synonym of Pseudechis, and more work is needed to understand species limits among the smaller species of the group.
