Researchers have found and identified a new species of frog, the size of a pea: Microhyla nepenthicola. For the past century, this critter was previously thought to be the infant form of another frog species. It resides inside carnivorous pitcher plants in Borneo. And, occasionally, on the tips of the endangered Blackwing Pencil.
Here is the National Geographic News story, and photo gallery.
