Seychelles: Frogs who hear through the mouth




Seychelles: Frogs who hear through the mouth
A scientific team of the CNRS and the University of Poitiers has made a surprising discovery on the Seychellois Gardiner’s frog that lives in the tropical forests of the archipelago.

Tropical frog Gardiner no more than a centimeter is thus devoid of ears, which could suggest that the frog was deaf.

But by broadcasting in the natural habitat of the pre-recorded croaks of the small amphibian, male frogs answered the call to the amazement of scientists.

After several working hypotheses to pierce the mystery of the Gardiner frog auditory, X-rays have revealed that it is his mouth which serves to amplify the frequencies emitted.
