DWARF UNDERWATER FROG
African dwarf frogs live their entire lives underwater, but need to rise to the surface to breathe air because they have lungs and not gills. These frogs are small in size and do not weigh more than a few grams. They vary in color, for the most part ranging from olive green to brown with black spots. The average life expectancy of these frogs is five years, but they can live as long as 20 years; they can grow to 6.35 cm (2.5 in) long. When young, African dwarf frogs can be mistaken and sold as African clawed frogs, of the genusXenopus, which are larger and more aggressive than the dwarf.
