This cute little guy is thought to be the world’s smallest frog. Measuring just 7mm long it has recently been discovered in Papua New Guinea. Called Paedophryne amauensis it lives amongst the leaf litter on the forest floor where it is well camouflaged. It was only found when researchers studying frog calls triangulated frog calls in the forest and found they were coming from the forest floor. Putting a handful of leaf litter within a plastic bag revealed the tiny frogs.
