The Brazilian gold frog (Brachycephalus didactylus), also known as Izecksohn's toad, is the second smallest frog in the Southern Hemisphere. The smallest is Paedophryne amauensis of Papua New Guinea, described in 2012.

Adult Brazilian gold frogs measure to only 9.6–9.8 mm (0.38–0.39 in) in body length. Many have a beautiful golden color, which explains their common name.

The smallest frogs of the Northern Hemisphere are the Cuban Eleutherodactylus iberia, which is similar in size, and Eleutherodactylus limbatus, of which fully mature adults as small as 8.5 mm have been found, though more typically 8.5 to 12 mm
