Aromobates – Skunk frogs

Known for their vile-smelling skin secretion that is released for defense purposes and contains the same stink-producing compound present in the famously foul anal emissions of skunks, these frogs are found in the Andes of Venezuela and Colombia, where they inhabit a wide range of habitats but prefer warm and wet areas.

Despite their foul odor, they possess more antibacterial substances than any other group of organisms on the planet. Researchers think there is real hope that these chemicals may serve as new weapons in the battle against antibiotic-resistant bacteria.
