Poison dart frogs are hard to miss. The first, published in April in the journal ZooKeys, describes the teal and black Ranitomeya aquamarina. Dart frogs have a complex evolutionary history of species emerging and subsequently re-hybridizing. Deforestation, climate change, increasingly frequent wildfires, and pet trade poaching all threaten poison dart frogs. Chemicals from the skin of specific dart frogs have shown promise as possible medicines.
