Paedophryne amauensis is a species of frog discovered in Papua New Guinea. It is notable for being one of the smallest vertebrates in the world, measuring just about 7.7 millimeters in length. This tiny frog has a brownish coloration that helps it blend into its forest habitat, making it less visible to predators. The species was first described in 2009 and is part of the Microhylidae family. Paedophryne amauensis primarily inhabits leaf litter in tropical forests, where it feeds on small insects. Its small size and unique adaptations make it an interesting subject for researchers studying biodiversity and evolution.
