Baleen whales sing. Toothed whales click. But how and why do they make these musical sounds?

Join Molly and co-host Tyler as they dive into the wonderful world of whale sounds. First, they run into Anna Goldfield on her way to audition for a whale choir. She teaches them about the voice boxes of baleen whales. Then, biologist Shane Gero talks about sperm whale communication, and how humans are only just beginning to understand the complexity of the sounds they make. All that, plus a whale of a mystery sound!

Are whales communicating with their clicks and songs?

Listeners send us LOTS of questions. Like hundreds a month! We read every single one — and we love all of them! Every now and then, we get a special kind of question that starts with “Is it true that…?” These questions are special because they’re skeptical. They’re designed to seek out the truth.

In this episode, Molly and co-host Meyer tackle three “Is it true that…” questions. First, they’ll explore whether twins can feel each other’s pain. Then, they’ll find out if the Vikings had horns on their helmets! They’ll end their quest by discovering whether dogs can see color like we do. All that, plus a tricky new mystery sound!
