Poison dart frogs is the common name of a group of frogs in the family Dendrobatidae which are native to Central and South America. These species often have brightly-colored bodies. Although all wild dendrobatids are at least somewhat toxic, levels of toxicity vary considerably from one species to the next and from one population to another. Many species are critically endangered. These amphibians were often called "poison arrow dart frogs" due to the Amerindians indigenous use of their toxic secretions to poison the tips of blow darts. Most species of poison dart frogs are small, sometimes less than 0.59 inches (1.5 cm) in adult length.. They weigh about 2 grams. Most poison dart frogs are brightly colored, displaying aposematic patterns to warn potential predators. When born and raised in captivity, poison frogs do not produce the skin toxins which they retain in their native habitat. Zoo shot. Info from Wikipedia.
