The Strawberry Poison-dart Frog, also called the Blue-jeans Frog, is one of the most ‘popular’ frogs in Costa Rica. Its brilliant red head and back and blue-to-purple legs comprise a coloration distinct from all other frogs. The frog’s bright colors warn off predators because the colors signal the toxicity for which the Poison-dart is named. The Strawberry Poison-dart frog is not known to be lethal to man, but its skin secretions may have unpredictable effects on humans.
