Darkwave - Underwater languages at the brink of extinction
Is there a whale culture? A voice? A mind? We humans find this idea compelling, and we always have. Ancient myths about whales and dolphins exist in every seafaring society. They have appeared as escorts of Aphrodite, Atargatis and Eros. As the saviours of the Maori, carrying New Zealand's first inhabitants onto the island. And of course, there is Eah-toop the right whale whose back formed the base of the universe for the Nuu-Chah-Nulth First Nation on Canada's West Coast.
But today whales are threatened by us, their language eroding through noise and climate change. Carrie Haber explores how marine scientists around the world are thinking about our evolutionary courtship with these magnificent mammals in the sea. **This episode originally aired September 28, 2016.
"Until about ten or fifteen years ago it was a bit dangerous to talk about animal culture in scientific meetings. There were people who were bound to jump out of their chairs and say that human cultures are so different from the kinds of social conventions that developed with animals. So it's not useful to use the same word, it's not useful to compare them. I think that's pretty much gone away, now. With the sort of large-brained social species like whales, like some of the higher primates, we really constrain ourselves in terms of how we can think about them, if we start from the premise that they're fundamentally different from us and there are no lessons to learn from humans. So some of us, myself included, threw that idea out ten years ago at least. And said ok, well there are parallels to that which we can draw between the two kinds of species."

- The Dominica Sperm Whale Project -The Dominica Sperm Whale Project is an innovative and integretive study of the world's largest toothed whale. Through thousands of hours of observation of sperm whale families, the population of whales in the Caribbean has given us the unique opportunity to come to know them as individuals within families. Our program is the first to have followed sperm whale families of whales across years. Now 10 years into the program, we have followed many calves from birth through weaning and we now know that some families have been using the region for decades. No sperm whale population has been this well characterized and the detailed behavioural histories of these individuals are rare among mammals, particularly in the ocean.
