Three recent expeditions to Costa Rica have uncovered 5,000 new species of life. Three of them were previously unknown species of salamander. One of those was super tiny.

This one, the dwarf salamander (Nototriton sp.) grows to little bigger than a thumbnail (about an inch). We've always known that slippery and slimy can come in itty-bitty packages, but now we know it can also come with four legs.

Thanks for the article, Jeri.
