Patagonia Frog vs Four-eyed Frog: common questions
Which frog is more restricted in range?
The Patagonia frog is, confined to a small number of cold Andean lakes, a far narrower range than the four-eyed frog's broader distribution across Chile and Argentina.
Which frog spends more time in water?
The Patagonia frog does, remaining almost entirely aquatic throughout its life, unlike the more terrestrial four-eyed frog, which spends most of its time on land.
Which frog uses false eyespots as a defence?
The four-eyed frog does, arching its back to display eye-like markings on its rump, a defence strategy the Patagonia frog does not use.
