They are more sensitive to pollution than most other animals with a skeleton, and because of this are indicator species that tell you how clean a water source is.
They eat all sorts of insects, including mosquito larvae, and are important in the food chain
Their skin contains chemicals that have been used as medicines and poisons.

poison dart frogs are used by central and south american tribes to poison darts (so that's where they got the name!) that they use to kill their prey
