28-3-2017 CARARA NAT PARK, COSTA RICA - GREEN AND BLACK POISON DART FROG (Dendrobates auratus)

The green-and-black poison dart frog (Dendrobates auratus), also known as the green-and-black poison arrow frog and green poison frog (among others), is a brightly-colored member of the order Anura native to southern Central America and Colombia. This species has also been introduced to Oahu, Hawaii in an effort to lower mosquito numbers. It is one of the most variably colored species of poison dart frogs, after D. tinctorius, Adelphobates galactonotus and some Oophaga species. From a conservation standpoint, it is considered to be of least concern by the International Union for Conservation of Nature. Within the reptile and amphibian hobby, D. auratus remains one of the most commonly kept, and easiest-to-breed, dart frogs in captivity, as well as in zoos.

The green-and-black poison dart frog is found in humid lowland and submontane forests at altitudes of 0–1,000 m (0–3,280 ft) in southeastern Nicaragua on the Atlantic slope, eastern Costa Rica on the Atlantic slope and in the southwest on the Pacific slope, widely in Panamá, and into far northwestern Colombia in the Chocó Department. An introduced population exists on Oahu, in Hawaii; the species was intentionally introduced there, in 1932, for mosquito control. Later on, it seems to have also become established on Maui.
