The Brazilian Gold Frog (Brachycephalidae didactylus), also known as Izecksohn's Toad, is the smallest frog in the Southern Hemisphere. It was previously called Psyllophryne didactyla. Adult Brazilian Gold Frogs measure to only 9.8 millimeters in body length. Many have a beautiful golden color, for which they are named after.

The smallest frogs of the Northern Hemisphere are the Cuban Eleutherodactylus iberia, which can be two-tenths of a millimeter smaller, and Eleutherodactylus limbatus, of which fully mature adults as small as 8.5 mm have been found.
