Whether it’s the idea of contact with extraterrestrials, sign language with primates or practicing new tricks with the family dog, humans are fascinated by the idea of communicating with other species. For her recent New Yorker article “Talk to Me,” science writer and journalist Elizabeth Kolbert traveled to Dominica to report on CETI: The Cetacean Translation Initiative. Kolbert reports: “CETI represents the most ambitious, the most technologically sophisticated, and the most well-funded effort ever made to communicate with another species.”
Sperm whales use a series of clicks called “codas” to communicate with each other. For example, here is a “conversation” between “Roger” and “Rita,” two adult females near Dominica:
Roger: 1 + 1 + 3
Rita: 1 + 1 + 3, 1 + 1 + 3
Roger: 9 Increasing (9 clicks with ever-increasing intervals between each click)
Rita: 1 + 1 + 3
Roger: 10 Increasing
Rita: 1 + 1 + 3, 1 + 1 + 3
And so on…
The sperm whales around Dominica have a repertoire of around 26 codas. The CETI team aims to place temporary recording devices on sperm whales in the region to record and track patterns of codas. Like ChatGPT digests millions of webpages and has become incredibly proficient at predicting language patterns to come up with answers and creative output, so CETI hopes that a computer model can learn to digest and predict codas, thus creating communication a whale would understand.
The idea of communicating with a whale in this way is interesting, but I was asking myself, “What’s the endgame? To help them? To help ourselves? Create increased empathy or knowledge?” I agree with Kolbert that the late biologist Roger Payne has a good answer. Payne was known for recording humpback whale “songs” that were released as an LP. These “songs” inspired empathy in humans and helped lead the way in the fight to rescue certain whale species from extinction. Payne was an early supporter of the CETI project. He said, “Inspiration is the key… If we could communicate with animals, ask them questions and receive answers—no matter how simple those questions and answers might turn out to be—the world might soon be moved enough to at least start the process of halting our runaway destruction of life.”
