According to wikipedia –

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 25 cm (10 in) long—tadpole (typical of the genus Pseudis), which in turn becomes an ordinary-sized frog, only about a quarter of its former length.
