(118K) The Rana Dorada or Golden Frog (Atelopus zeteki) is the most cherished frog in Panama yet it is in danger of extinction. Researchers believe the primary threat to these beautiful frogs is the loss of habitat due to logging, farming and cattle ranching. Smithsonian Tropical Research Institute Photo by Carl C. Hansen.

(170K) Poison Dart (or Poison Arrow) frogs receive their name because South American Indians use toxic alkaloids contained in the skin of certain species to poison the tips of their blowgun darts when hunting animals for use in religious ceremonies. Most members of this family are brilliantly colored, presumably as a warning to predators. This species, Dendrobates auratus, is common in the tropical forests of Panama and Costa Rica.
