Do Sperm Whales Talk to Each Other?

This week, we turn away from the media for a moment, to a realm thousands of feet beneath the ocean’s surface – where sperm whales swim. These behemoths spend most of their lives in complete darkness, surfacing only for a few minutes at a time. They have the largest brains of virtually any other creature on earth, and they grow to be the size of one school bus, even two – and weigh as much as ten of them. But despite leading wildly different lives, scientists say they may communicate with each other – much like we do. 

In May, scientists at CETI, or Cetacean Translation Initiative, published a study claiming that they use a complex phonetic alphabet that echoes the structures of human languages. This week, host Brooke Gladstone speaks with Shane Gero, a biologist focusing on the acoustic complexity and social behavior of whales and Biology Lead at CETI, about this phonetic alphabet, and how it might be the first of many steps that could lead to translating what these sea giants are saying – and saving their lives.
