Blue Poison Dart Frog

“Poison dart frogs, members of the Dendrobatidae family, wear some of the most brilliant and beautiful colors on Earth. Depending on individual habitats, which extend from the tropical forests of Costa Rica to Brazil, their coloring can be yellow, gold, copper, red, green, blue, or black. Their elaborate designs and hues are deliberately ostentatious to ward off potential predators, a tactic called aposematic coloration.”
