The Whale Song That Crossed an Ocean (Real Humpback Recordings)

In 1995, scientists off the east coast of Australia heard two humpback whales singing a brand-new song — one that had come from the Indian Ocean. Within two years, every male on the coast was singing it. And then the songs began to travel across the entire South Pacific, from singer to singer, like hit songs spreading around the world. In this episode — with real recordings of humpback whale song: how whale songs are built, the "cultural revolution" off Australia, how sound travels thousands of kilometers through the ocean, the mysterious 52-hertz whale, a 2025 discovery about language-like patterns in whale song, a 20-minute "conversation" with a whale named Twain — and the whale song that is now flying through interstellar space on Voyager 1. Episode 2 of "Wild Minds" — the astonishing intelligence of animals.
