Dart poison frogs from the rainforests of the Americas come in a dizzying array of colors and patterns. Some are used by native tribes to poison the tips of blowdarts for hunting. Complex compounds in the skin secretions of dart frogs are now being studied by scientists for potential medical use. These frogs have provided a possible substitute for morphine that is non-addictive and 100 times more potent.
The blue dart poison frogs (Dendrobates tinctorius) featured in Frogs: A Chorus of Colors are between 1 and 1.5 inches long and are active during the day. In the wild, these dazzling little frogs can be found hiding among boulders and debris near streams.
