High doses of

This estimate will vary in turn, but most agree this dose is enough to kill between 10 and 20 humans, which correlates to up to two African bull elephants. This is roughly 15,000 humans per gram. This extraordinarily lethal poison is very rare. "Batrachotoxin" is only found in three poisonous frogs from Colombia (genus "Phyllobates"), a few birds from Papua New Guinea, and four Papuan beetles of the genus "Choresine" in the family Melyridae; "C. pulchra", "C.
