A Multitude of Morphs: Harlequin Dart Frogs - Pictured here is the Koi morph. These are Harlequin Poison Dart Frogs (Oophaga histrionica, Oophaga sylvatica - two “different” [this is debated] species). These creatures come in a multitude of color.
Twinkling in the dimmest of places within the tropical jungles of South America is the Fringe-limbed Tree Frog (Cochranella euknemos). Its name euknemos derives from Greek and means "with beautiful legs," which refers to the frog's fringed hind limbs.
