We long believed they were mute and deaf, but it turns out tortoises can speak! In a fragmented yet refined manner, at low frequencies they are able to communicate across great distances in deep waters and at high frequencies in shallow waters to locate each other. But that is not it—even their embryos "speak" to each other and agree on when to hatch out of their eggs. This program 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!
