List of dangerous snakes
The Eastern green mamba ("Dendroaspis angusticeps") has an average venom yield per bite of 80 mg according to Engelmann and Obst (1981). The subcutaneous for this species ranges from 0.40 mg/kg to 3.05 mg/kg depending on different toxicology studies, authority figures and estimates. The mortality rate of untreated bites is unknown but is thought to be very high (70-75%). Generally the calmest and most shy of the green mamba species, the Eastern green will still strike repeatedly if cornered or agitated.
