Conservationists are celebrating the establishment of a new nature reserve in Colombia that provides the first sanctuary for the endangered golden poison frog, an animal that also has the distinction of being possibly the world’s deadliest animal. Its poison is so toxic that even coming in contact with a paper towel that has touched the frog has been fatal to animals. Although they are only two inches long, it is estimated that each golden poison frog has enough toxin to kill ten adult people within minutes.
(Here's my favorite picture of a frog--a different kind of frog. And my favorite video of a weird frog.)
