Last summer, news reports of orcas deliberately tearing the propellers off of yachts in the Strait of Gibraltar thrilled observers who were eager to cast these intelligent and social pack hunters as class warriors striking a blow for the “common mammals” against the one percent. That turned out to be wishful thinking, according to guest Lori Marino, a biopsychologist who studies whale and dolphin intelligence. She told us that these six-ton whales were just having fun—if they wanted to harm the occupants of those boats, we’d know it.

Even so, these encounters are becoming a predictable seasonal occurrence between the months of May and August: A 50-foot charter vessel sank after its hull and rudder were damaged in an orca encounter near the Strait of Gibraltar on May 12. So here again is our episode on the perils of assigning human motives to wild animals, featuring Marino and Smithsonian assistant digital science editor Carlyn Kranking. This episode was originally released in September 2023.

Dr. Marino invites you to learn more about The Whale Sanctuary Project at their site. You can also see Dr. Marino in the documentary films Blackfish (2013), Unlocking the Cage (2016), and Long Gone Wild (2019).
