Which snake genus contains the death adders?

The snake genus that contains the death adders is Acanthophis.

Acanthophis is a genus of venomous snakes commonly called death adders. Despite their viper-like appearance, death adders are elapids, placing them in the same broad family as cobras and taipans. Their stout bodies, triangular heads, and short tails evolved independently of true vipers.

Death adders are ambush predators. They often lie concealed and use the tail as a lure, moving its tip to attract prey such as frogs, lizards, and small mammals. When prey approaches, the snake can strike rapidly and inject venom through short, fixed front fangs.

The genus is native mainly to Australia and nearby regions, including New Guinea. The name “adder” reflects their resemblance to European adders, not close relationship. This is a useful classification distinction: appearance alone does not determine whether a snake is a viper or an elapid.
