Which venomous snake produces the largest quantity of venom per bite?

The Gaboon viper produces the largest quantity of venom per bite among venomous snakes. Its enormous venom glands allow it to deliver an unusually large volume when it strikes.

Native to sub-Saharan Africa, the Gaboon viper (Bitis gabonica) is a heavily built forest and savanna viper. A typical bite may inject roughly 450–600 milligrams of venom, while exceptionally large yields have been recorded. Its long, hinged fangs—among the longest of any venomous snake—can penetrate deeply.

This answer is often confused with the inland taipan, whose venom is vastly more toxic by dose. “Most venomous” can mean most potent, while this question concerns venom quantity. The Gaboon viper is generally sluggish and secretive, and human bites are uncommon, often occurring when the snake is accidentally stepped on.

Its venom is primarily cytotoxic and cardiotoxic, causing severe swelling, tissue damage, shock, and potentially life-threatening internal effects. Despite its fearsome reputation, it is not usually an aggressive snake.
