Researchers at the Centre de Neurosciences Paris-Sud believe they know why the Gardiner’s Seychelles frog always looks so shocked whenever they talk to it: the frog may use its mouth to listen.
The tiny frog that’s no larger than a fingernail lacks an inner ear that most animals — including people — use to hear. So, based on X-rays, they think that the frog uses its mouth as a replacement since it is the only part of its anatomy that resonates at the proper frequency.
They would study the frog further to confirm this theory, but that would mean continuing to talk to frogs. And there’s nothing creepier than talking to someone with their mouth hanging open.
