A philosopher journeys into the world of comparative thanatology, which explores how animals of all kinds respond to death and dying.
In the summer of 2018, off the coast of British Columbia, an orca named Tahlequah gave birth. When the calf died after just half an hour, Tahlequah refused to let go. For more than two weeks, she carried her calf’s body around, often balancing it on her nose as she swam.
The story went viral, which came as no surprise to Susana Monsó, a philosopher of animal minds at the National Distance Education University in Madrid. Despite the vast chasm that seems to separate humans and killer whales, this orca mother was behaving in a way that was profoundly relatable.
“This idea of a mother clinging on to the corpse of her baby for 17 days seems like something we can understand, something we can relate to, for those of us who have experienced loss,” Dr. Monsó said.
Of course, projecting our own human experiences onto other species can be a tricky business, and scientists often warn about the mistakes we can make when we engage in this sort of anthropomorphism. But we can also be misled by our tendency to assume that many cognitive and emotional traits are unique to humans, Dr. Monsó said. And in her new book, “Playing Possum,” she argues that a variety of animal species have at least a rudimentary concept of death.
Dr. Monsó spoke with The New York Times about her work. This conversation has been condensed and edited for clarity.
