In 2007, our guest, Fabrice Schnoller, was sailing off the coast of Mauritius when he had an encounter that would change his life and open a new frontier in marine biology. As his boat neared land, huge pillars of steam burst out of the water. When Schnöller jumped in to investigate, he was overwhelmed by a crashing, creaking sound. It was the echolocation clicks of sperm whales, the bearers of the largest brains ever known to have existed on Earth. In addition to helping whales navigate, some evidence suggests that these clicks also function as a language. To investigate this possibility, Schnöller founded DAREWIN, the first initiative devoted to studying whale click communication and exposing it to the wider public. In the nine years since the project launched, Schnoller and his team have amassed the largest database of sperm whale vocalizations in history — all collected non-invasively, through free-diving. We speak with Schnöller about DAREWIN’s work, its pioneering methodology, and what it’s like to be X-rayed by a whale.
In mountainous regions of the world, there are human societies that use whistled languages to transmit and understand a potentially unlimited number of meanings over great distances. While in graduate school, Dr. Diana Reiss began to wonder: If humans can encode great amounts of information in whistles, perhaps much more is going on with the whistles of dolphins than we once thought. Reiss
is an internationally renowned expert on dolphin intelligence and a Professor of Psychology at Hunter College in New York City. With colleagues, she was the first to demonstrate
that dolphins can recognize themselves in mirrors, a capability once thought to be unique to humans, and has taught dolphins to communicate with underwater interactive keyboards. In this episode, she describes how she got early support for her work from SETI
researchers, John Lilly’s complex role in shaping scientific and public interest in dolphins, the parallels between dolphin and human whistle languages, the importance of anecdotal experiences in science, and her advocacy work to end dolphins hunts in Japan.
