Dart-poison frogs : Everyone who visits the Central Park Zoo is amazed at the coloration of these frogs…for the Wildlife Guides it is the perfect opportunity to reveal that in nature, the more colorful an animal is, the more poisonous. These frogs are aposematic, meaning their coloration serves as a warning to predators. In the wild their skin emits a neurotoxin. They cannot be touched by and humans must use leaves to handle them because this poison will cause paralysis or even death. Because the frogs are not poisonous in captivity, it is thought that their toxicity is due to their wild habitat diet of ants.
