(Linnaeus, 1758)
Pseudis paradoxa, known as the paradoxical frog or shrinking frog, is a species of hylid frog from South America.[2] Its name refers to the very large—up to 27 cm (11 in) long—tadpole (the world's longest), which in turn "shrinks" during metamorphosis into an ordinary-sized frog, only about a quarter or third of its former length. Although the recordholder was a tadpole in Amapá that belonged to this species, others in the genus Pseudis also have large tadpoles and ordinary-sized adults.[3][4][5]
