Whales and dolphins are, without a doubt, some of the most charismatic, enigmatic creatures around. Part of what draws us to them is that—different as our worlds are from theirs, different as our bodies are—we sense a certain kinship. We know they’ve got big brains, much like we do. We know that some cetacean species live long lives, sing songs, and form close bonds. If you’re like me, you may have also wondered about other parallels. For example, do whales and dolphins have something we might want to call culture? If so, what do those cultures look like? What sorts of traditions might these animals be innovating and circulating down in the depths?
On this week’s episode I chatted with Dr. Luke Rendell, a Reader in the School of Biology and a member of the Sea Mammal Research Unit at the University of St Andrews in Scotland. He’s been studying cetaceans for more than two decades. He’s the author, with Hal Whitehead, of the 2014 book The Cultural Lives of Whales and Dolphins. (You can probably guess by the book’s title where Luke comes down on the question of cetacean culture.) Luke’s work is, to my mind, an impressive blend of naturalistic observation, cutting edge methods, and big-picture theorizing.
In this conversation, Luke and I do a bit of “Cetaceans 101.” We talk about what culture is and why whale song is a good example of it. We discuss lob-tail feeding in humpback whales and tail-walking in bottlenose dolphins. We talk about Luke’s very recent work on how sperm whales in the 19th century may have learned from each other how to evade whalers. And we discuss why an understanding of culture may be crucial for ongoing cetacean conservation efforts.
We didn’t plumb all the depths of this rich topic—nor did we exhaust all the maritime puns—but we did have a far-reaching chat about some of the most fascinating beings on our planet and their distinctive cultures. As always, thanks a bunch for listening folks. On to my conversation with Dr. Luke Rendell. Enjoy!
