This critically endangered amphibian only grows to be about 10mm in snout to vent length—that’s 0.39 of an inch! Eleutherodactylus iberia is the smallest frog in the Northern Hemisphere. It’s found in eastern Cuba, including in Parque Nacional Alejandro de Humboldt, which is where Museum researcher Chris Raxworthy snapped this photo in 2015 while on the Explore21 Expedition to Cuba. Much remains unknown about this tiny species, as it was first discovered in 1996.
