The Blue Dart Frog lives in Central and South America and some Hawaiian islands. They are brightly colored blue with black spots to warn predators they are poisonous. The female frog lays eggs on land which the male fertilizes and guards; tadpoles then wiggle onto the female's back to be carried to water, where they develop over 6-8 weeks before living on land as frogs. Blue Dart Frogs help the environment by eating insects but are threatened by habitat loss and use of their poison.
