Bitis Gabonica, commonly known as the Gabon viper, is a venomous viper species found in the rainforests and savannas of sub-Saharan Africa. It is not only the largest member of the genus bitis, but also the world’s heaviest viperid, and it has the longest fangs and the highest venom yield of any venomous snake.

Angolan scientist Paula Regina de Oliveira said the species of Bitis Gabonica are the ones with teeth that could reach five centimeters long and larger glands, which allow them to accumulate large amounts of venom.
