Titicaca Water Frog

The Titicaca water frog is a large, fully aquatic frog, family Telmatobiidae, found only in Lake Titicaca and a handful of connected rivers and lakes in the Andean highlands of Bolivia and Peru. Its skin hangs in loose, baggy folds that greatly increase surface area, letting the frog absorb enough oxygen directly through its skin to survive at high altitude without regularly surfacing for air. Habitat degradation and overharvesting for human consumption have left it endangered.
