Poison dart frogs, or dendrobatids, belong to one of the most poisonous animal families in the world. Native tribes in the frogs' habitats often tip the darts for their blowguns with the poison when hunting.
Poison dart frogs live in the rain forests of Central and South America, from Costa Rica through Brazil. The colors of the species varies from one habitat to another. They have vibrant color schemes of red, yellow, gold, blue and black as well as green or copper that clue predators to their poisonous nature. The golden poison dart frog is no bigger than a standard paper clip, but it possesses enough poison to kill 10 people. A snake called Leimadophis epinephelus is the only natural predator for these amphibians, since it has built up a resistance to the toxins.
