Poison dart frogs got that name not because the frogs have poison darts - they haven't - but because humans used the poison from the frogs to poison their darts.
There are many species of poison dart frogs, but the genus names are Dendrobates, Phyllobates, Mantella, Ameerega, Oophaga, Ranitomeya and Hyloxalus. Until recently most species were withing Dendrobates, Phyllobates and Mantella, but they have undergone revisions and additions.
