Using AI to decode clicks from sperm whales, the scientists discovered a sophisticated alphabet hidden in the animals' sounds. And similar to Morse Code, their clicks are what they mainly use to communicate and socialize with other sperm whales. AdvertisementThinking like baby whalesA Project CETI collaborator holds the drone that the researchers use to observe sperm whale behavior and body language. Project CETIIn partnership with the Dominica Sperm Whale Project, Project CETI observes and documents sperm whale communication using a variety of different technologies. The researchers supplement these auditory recordings with drone surveys of the whales' body language and field observations taken by Project CETI researchers.

No one knows what all the sperm whale codas mean, but they can have distinctive rhythms and tempos, known as “dialects,” Hersh said. They’ve now determined that there are at least seven distinct sperm whale “vocal clans” across the Pacific Ocean, each with their own identity codas, Hersh said. And the sperm whale clans may be thousands of years old. Beguš is part of Project CETI — the Cetacean Translation Initiative — which was established last year to decipher the sounds of sperm whales. “As the authors note, we still understand little about the function of sperm whale codas,” she said in an email.
