Frogs in the rainforest
Many people do not realize the amazing varieties of frogs that exist in the rainforest. Most of these frogs are extremely exotic and colorful. For example, there are tiny tree frogs and the poison arrow frog. These frogs are extremely colorful (and poisonous); however, some frogs have been found to have internal chemicals which may aid in the production of antibodies and other medicines to prevent deadly diseases.
