This is a checklist of amphibians found in Northern America, based mainly on publications by the Society for the Study of Amphibians and Reptiles. [1] [2] [3] The information about range and status of almost all of these species can be found also for example in the IUCN Red List of Threatened Species site. [4]
Oophaga is a genus of poison-dart frogs containing twelve species, many of which were formerly placed in the genus Dendrobates. [1] The frogs are distributed in Central and South America, from Nicaragua south through the El Chocó to northern Ecuador (at elevations below 1,200 m (3,900 ft)).
Batrachotoxin has also been found in all described species of the poison dart frog genus Phyllobates from Nicaragua to Colombia, including the golden poison frog (Phyllobates terribilis), black-legged poison frog (P. bicolor), lovely poison frog (P. lugubris), Golfodulcean poison frog (P. vittatus), and Kokoe poison frog (P. aurotaenia).
