golden poison frog

Over 80 kinds of poison frogs live in the tropical forests of Central and South America. Of these, the toxin of the jewel-bright golden poison frog is 10 to 20 times more deadly than any other poison frog. Golden poison frogs get their toxicity from something in their diet. Scientists think the poison comes from a certain kind of beetle. In captivity, the frogs are fed toxin-free crickets and flies, so they're harmless.
