Phyllobates bicolor ‘Green Leg’. These frogs are commonly called the Black Legged Dart frog or the Bicolored Dart Frog. P. bicolor are also known as neari by native tribes in Colombia. Sometimes, Phyllobates bicolor ‘Green Leg’ is also known as ‘Green Legged’, or Green Leg/Legged bicolor. In the hobby, they are sometimes simpley referred to as bicolor. In the past, this species of poison dart frog has been known as Phyllobates chocoensis andPhyllobates melanorrhinus. Phyllobates bicolor is one of the ‘deadly 3’ true dart frogs (and the second most toxic vertebrate on the planet), which are utilized by native indian tribes in Colombia to poison darts for hunting. Fortunately, bicolor (like all dart frogs) are harmless in captivity, as they get their toxins from their wild diet.
