The Paradox Frog, Pseudis paradoxa, is native to South America found in the warm tropical lowlands of the Amazon forest, and other regions in the neighbourhood.
It is considered a paradox after it thoroughly confused early biologists who happened upon it. They first decided that a young frog grew into an old tadpole, which would be the complete opposite of every other frog on earth. That, however, was just a misunderstanding of a very peculiar trait of this little froggy.
It’s babies are four times bigger than the parents.
While the adult Paradox Frogs are 7 centimeters (about 2.7 inches), which is pretty standard for frogs, the young tadpoles can be up to 25 cm (9.8 inches) from tip to tail. To put that in perspective for my human readers, that’s a 20-foot-tall teenager!
As the tadpoles go through their metamorphosis, sprouting legs, they will shrink down to adult size.
