Though its bites cause death only ~1% of the time, these snakes are considered dangerous as they are very prevalent, and cause death years after the bite more frequently than other snakes. Their hemotoxic venom affects the heart and vessels in such a way that they are sometimes unable to deal with the stresses of aging. Bilder-atlas zur wissenschaftlich popularen.
