green and black poison dart frog
''Dendrobates auratus'', also known as the green and black poison dart frog or the green and black poison arrow frog, and sometimes mint poison frog (not to be confused with the mint-green color morph of ''Phyllobates terribilis''), is a brightly colored member of the order Anura native to Central America and northwestern parts of South America. This species has also been introduced to Hawaii.〔http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=49〕 It is one of the most variable of all poison dart frogs next to ''Dendrobates tinctorius'' and some ''Oophaga'' spp. It is considered to be of least concern from a conservation standpoint by the International Union for Conservation of Nature (IUCN).
== Poison ==
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.〔http://news.nationalgeographic.com/news/2007/05/070514-poison-frogs.html〕
