Poison Dart Frog Mouse Pad Poison dart frog (also dart-poison frog, poison frog or formerly poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to Central and South America. Unlike most frogs, species are active during the day, and often exhibit brightly-colored bodies. Although all dendrobatids are at least somewhat toxic in the wild, levels of toxicity vary considerably from one species to the next, and from one population to another. Many species are critically endangered. These amphibians are often called "dart frogs" due to indigenous Amerindians' use of their toxic secretions to poison the tips of blowdarts.[1] In fact, of over 175,000 species, only three have been documented as being used for this purpose (curare plants are more commonly used), and none come from the Dendrobates genus, which is most characterized by the brilliant color and complex patterns of its members. Most species of poison dart frogs are small, sometimes less than 1.5 centimetres (0.59 in) in adult length, although a few are up to 6 centimetres (2.4 in) in length. Most poison dart frogs are dully colored, displaying aposematic patterns to warn potential predators. Unlike most other frogs, they are diurnal, rather than being primarily nocturnal or crepuscular.[4] They lay their eggs in moist places, including on leaves, in plants, among exposed roots, and elsewhere, and allow the tadpoles to wriggle onto their backs shortly after they hatch. They then carry the piggy-backed tadpoles to water, where the larva remain until metamorphosis. The water is typically a pool, but some species use the water gathered in bromeliads or other plants; and some species provide food, supplying the tadpoles with unfertilized eggs to drink Poison dart frogs are endemic to humid, tropical environments of Central and Latin America (South America).[2] These frogs are generally found in tropical rainforests, including in Bolivia, Costa Rica, Brazil.
