Scientists discover ancient frog that swallows sound

French Scientists revealed Monday how they believe the mysterious “earless” Gardiner’s frog can actually hear: by swallowing sound with its mouth.

One of the smallest frogs in the world, the dime-sized Gardiner’s frog is from the Seychelles islands, and apparently, it detects sound through the vibrations in its mouth. Previously, scientists were baffled as to why these petite amphibians appeared deaf, but spent their time croaking away. New research using detailed x-ray imaging has revealed that the frog’s mouths amplify and resonate sounds similar to the eardrum of other species. The findings were reported in the US journal the Proceedings of the National Academy of Sciences.
