Poison dart frog

"Stop! Hold very still... You dare not let it touch your skin."

- Hector Barbossa to Joshamee Gibbs when a Poison Dart Frog jumped on his shoulder

Poison Dart Frogs were a kind of frog that were native on the unnamed island, where the Fountain of Youth was located. These creatures were very poisonous. Barbossa claimed that a man could die within minutes if he ever touched a Poison Dart Frog. Many of these frogs were captured by Barbossa so that he could use their poison to make his sword deadly. The poison proved to be very effective when Barbossa later stabbed Blackbeard during a battle at the Fountain of Youth.
