Notes on Meaning

This term refers specifically to a single biological species. Its key distinguishing features are its highly venomous nature, its Australian habitat, and its viper-like morphology (which is unusual among elapid snakes). The "resemblance to an adder" noted in some definitions refers to its convergent evolution with vipers, not a close genetic relationship.
