Poison dart frogs are small, brightly colored amphibians native to Central and South America. These frogs are known for the toxic secretions on their skin, which have been used by indigenous people to poison the tips of hunting darts and arrows. Despite their reputation as being poisonous, poison dart frogs are not actually harmful to humans unless ingested. In fact, these frogs are popular pets due to their vibrant colors and small size. However, it is important to be cautious when considering purchasing a poison dart frog, as they have specific care requirements and are not suitable for all individuals.
