Poison dart frogs are small, brightly colored frogs found in Central and South America. They get their name from the indigenous people's use of their toxic secretions to poison the tips of blowgun darts for hunting. Despite their small size, poison dart frogs are one of the most toxic species in the world, with some capable of killing humans. However, their toxicity is only present in their natural habitats, where they consume toxic insects. In captivity, their diet is less toxic, making them safe to handle. They are also popular in the pet trade due to their bright colors and small size.

The two-inch-long poison frog has enough poison to kill 10 grown men.
