16. Golden Poison Dart Frog
Apparently the cartel doesn’t have the most deadly reputation in Columbia. The golden poison dart frog, which can range in color from green to orange, lives on the Pacific coast of Columbia and has a deadly coating on its skin. Exposure can use heart failure or fibrillation. Doses between frogs can vary, but one milligram of the toxin is patent enough to kill 20 adult humans.
