Gardiner’s Frogs Use Their Mouths To Hear

Researchers say that Gardiner’s frogs, found on the Seychelles Islands off the coast of Africa, use their mouth cavity and tissue to transmit sound to their inner ears. These frogs, unlike other animals and even most other frogs, do not possess a middle ear, which is typically required for hearing. Numerical simulations and X-ray imaging showed that sounds travel through the oral cavity to the tiny frog’s inner ear due to reduced thickness of tissue and a smaller number of tissue layers between the mouth and inner ear. So it’s a combination of mouth cavity and bone conduction that lets these seemingly deaf frogs hear!
