As children, many of us kept frogs we had found in jars and vivariums, or just took them home to show to our friends. The frogs on this list are a different ball of wax, not creatures anyone in their right mind would want to play with or even touch - in many cases, in fact, they are deadly poisonous.

These frogs use their poison solely for self-defense, not to kill prey, and what a good defense against predators it is. Many of them are poison dart frogs known for their use in making arrow poisons. Beautiful but deadly – it's definitely a case of look but don't touch with these suckers!
