Poison dart frogs are extremely beautiful but extremely poisonous. Their brightly colored bodies serve as a good defense system as the color signals that the frog is poisonous. The poison of the poison dart frog comes from their diet of ants, termites and other insects. The weak poison from the insects is then concentrated in the frog into a much stronger poison. Poison dart frogs raised in a controlled environment are not poisonous as they do not have access to the insects found in the rainforest.

Did you know that? Poison dart frogs have a natural enemy, the snake Leimadophis epinephelus. The snake is resistant to the frogs' venom.
