Golden Poison Frog
As evidenced by its scientific name Phyllobates terribilis, the golden poison frog, or golden dart frog, is a deadly creature. "Not only is it the most poisonous frog, but it is believed to be the most poisonous animal in the world," Centuori says. "A single frog has enough poison in its body to kill 20,000 mice or 10 people." The frog, which guests can see during the exhibit, measures about 2 inches when fully grown. Just touching one has the potential to kill you.
