Worlds smallest frog

A tiny frog recently discovered in the forests of Papua New Guinea has been decreed the smallest of the known 60,000 species of vertebrates (the group that includes mammals, fish, amphibians and birds). The tiny creature is around 7mm long (half the size of a Smartie) and lives well camouflaged among leaf litter – which could explain why it remained unnoticed for so long.
It was its high-pitched call, more like an insect’s than a frog’s, that first attracted the US team’s attention. “The New Guinea forests are incredibly loud at night. We were trying to record frog calls, and we were curious as to what these other sounds were,” said Chris Austin of Louisiana State University, who led the research. “So we triangulated to where these calls were coming from, and looked through the leaf litter.” But in the dark it was almost impossible to see anything – so the researchers simply grabbed a handful of litter and popped it into a clear plastic bag. It was only then that they saw a load of “incredibly tiny frogs hopping about”, Austin told BBC News online.
