Dendrobates auratus
Small frog, less than 1" in length. Per the attached Wikipedia article... "The green-and-black poison frog, while not the most toxic poison dart frog, is still a highly toxic animal. The very small amount of poison the frog possesses is still enough to make a human heart stop beating. Like most poison dart frogs, however, the green-and-black poison dart frog will only release its poison if it feels that it is threatened, and wild specimens can be handled if the human holding it is calm and relaxed. The green-and-black poison frog, as with all poison dart frogs, loses its toxicity in captivity due to a change in diet. This has led scientists to believe that the green-and-black poison frog actually takes its poison from the mites it feeds on.[2]" [2] http://news.nationalgeographic.com/news/...
This frog was spotted in the Costa Rican rainforest, above a muddy area.
