About 24 hours after being bitten on the thumb by a juvenile boomslang (also called a South African green tree snake), herpetologist Karl Patterson Schmidt died from internal bleeding from his eyes, lungs, kidneys, heart and brain, researchers reported in 2017 in the journal Biochimica et Biophysica Acta. The snake had been sent to Schmidt at The Field Museum in Chicago for identification. Like others in the field at the time (1890), Schmidt believed that rear-fanged snakes like the boomslang (Dispholidus typus) couldn't produce a venom dose big enough to be fatal to humans. They were wrong.
The boomslang, which can be found throughout Africa but lives primarily in Swaziland, Botswana, Namibia, Mozambique and Zimbabwe, is one of the most venomous of the so-called rear-fanged snakes, according to the University of Michigan Museum of Zoology. Such snakes can fold their fangs back into their mouths when not in use. As in other deadly snakes, this one has hemotoxic venom that causes their victims to bleed out internally and externally, the Museum reported.
