Newton - Secrets of Primeval Times - The Language of Tortoises

We long believed they were mute and deaf. But it turns out tortoises can speak! In a fragmented yet refined manner: at low frequencies to be able to communicate across great distances in deep waters . At high frequencies in shallow waters to locate each other. But that's not it: even their embryos 'speak' to each other and agree on when to hatch out of their eggs. Newton offers a fascinating peak into the most recent research on tortoises, dives right into their language and shatters some of the prejudice we hold against them. Because tortoises are talkative, fast and, above all, sociable!
