About the Poison Dart Frogs

There are about 220 kinds of poison frogs, all native to warm rainforests of Central and South America. Most are only 1 to 6 cm long. Their bright reds, yellows, greens and blues warn predators that they are poisonous. Poison frog parents carry their tadpoles on their backs to water, such as a pond or the little pool of water inside a bromeliad plant.[1]
