The phantasmal poison frog is not only beautiful, it is also exceptionally tiny. It grows to only about one half inch to one and a half inches in length. But don't let that small stature fool you. The phantasmal poison frog carries enough poison to kill an adult human.8
Scientists have looked into the possibilities of using epibatidine, a natural alkaloid which is the potent poison of this frog, to develop a non-addictive painkiller more powerful than morphine.9 While promising, scientists have determined that epibatidine may also be too toxic to humans.10
