Do Sperm Whales Talk to Each Other?
2Digest
This episode of On the Media's Midweek Podcast explores the fascinating world of sperm whale communication. Shane Garrow, a biologist studying sperm whales for two decades, reveals that these deep-sea giants use a phonetic alphabet, similar to humans, with over 150 codas. This discovery, made by Garrow and his team at SETI (Sustation Translation Initiative), opens up new possibilities for understanding their complex social interactions. Garrow emphasizes the importance of context in interpreting whale communication, noting that their vocalizations vary depending on their activities and social groups. He describes the existence of distinct dialects among sperm whale families, with different clans sharing specific coda types and exhibiting unique habitat use, movement patterns, and social behaviors. This cultural boundary, similar to human societies, highlights the importance of understanding their social structures for their conservation. Garrow shares the story of Digit, a young sperm whale entangled in fishing gear, highlighting the impact of human activities on their lives. He emphasizes the need for scientists to communicate their research effectively to engage the public in conservation efforts. Garrow believes that understanding the similarities between human and whale experiences can foster empathy and inspire action towards protecting these magnificent creatures.

Keywords
Sperm Whale
A large toothed whale known for its massive size, distinctive clicks, and deep-sea diving abilities. Sperm whales are the largest toothed whales and have the largest brains of any animal on Earth. They are found in all oceans and are known for their complex social structures and communication systems.
Phonetic Alphabet
A system of sounds used in a language, where each sound is represented by a distinct symbol. In the case of sperm whales, their phonetic alphabet consists of clicks grouped into codas, which they use to communicate with each other.
Coda
A group of clicks used by sperm whales in their communication system. Each coda represents a distinct sound or meaning, and they are combined to form complex vocalizations.
Dialect
A variation of a language spoken by a particular group of people, often characterized by differences in pronunciation, vocabulary, and grammar. In the case of sperm whales, different families have distinct dialects, which are reflected in their use of specific coda types.
Cultural Boundary
A line that separates different cultures or groups of people, often based on shared beliefs, values, and practices. In the case of sperm whales, cultural boundaries exist between different clans, which are defined by their shared dialects and social behaviors.
SETI
SETI stands for the Search for Extraterrestrial Intelligence. It is a scientific effort to search for signs of intelligent life beyond Earth. In this context, SETI is used as a play on words for "Sustation Translation Initiative," a project focused on translating sperm whale communication.
Conservation
The act of protecting and preserving natural resources, including wildlife, habitats, and ecosystems. Conservation efforts aim to ensure the survival and well-being of species and their environments.
Roger Payne
A renowned biologist and conservationist who made groundbreaking discoveries about whale communication. Payne's research on humpback whale songs revolutionized our understanding of these animals and sparked a global movement to protect them.
Marine Mammal Protection Act
A United States law passed in 1972 that protects marine mammals from hunting, harassment, and other threats. The act has been instrumental in the recovery of many marine mammal populations.
International Whaling Commission (IWC)
An international body established in 1946 to regulate whaling and protect whale populations. The IWC has played a significant role in reducing whaling activities and promoting whale conservation.
Q&A
How do sperm whales communicate?
Sperm whales communicate using a phonetic alphabet, similar to humans, with over 150 codas. They use clicks grouped into codas to convey information and interact with each other.
What are the different levels of social organization among sperm whales?
Sperm whale society is multi-tiered, with families at the base, clans sharing dialects and behaviors, and larger groups spanning vast distances across oceans.
What are the challenges facing sperm whale conservation?
Sperm whales face threats from human activities, including entanglement in fishing gear, ship strikes, and habitat destruction. These threats are a major concern for their survival.
What are the key ingredients for a successful conservation movement?
A successful conservation movement often involves a combination of factors, including a jarring image, a compelling fact, the identification of individuals, and a clear narrative that resonates with people.
How can scientists effectively communicate their research to the public?
Scientists need to communicate their research in a way that is accessible and engaging to the public, highlighting the importance of their work and its implications for conservation.
What are the potential benefits of understanding sperm whale communication?
Understanding sperm whale communication could provide insights into their social lives, cultural diversity, and cognitive abilities. It could also lead to better conservation strategies and a deeper appreciation for these magnificent creatures.
What is the ultimate goal of Project Ceti?
Project Ceti aims to translate sperm whale communication, understand their complex social lives, and inspire people to protect these animals and their ocean habitats.
What is the significance of Digit's story?
Digit's story highlights the impact of human activities on sperm whales and the importance of conservation efforts. It also demonstrates the power of storytelling in raising awareness and inspiring action.
What are some of the lessons we can learn from sperm whales?
Sperm whales teach us about the importance of cultural diversity, strong female leadership, and the interconnectedness of all living things. They also remind us of the need to respect and protect the natural world.
What is the role of scientists in conservation?
Scientists play a crucial role in conservation by conducting research, raising awareness, and advocating for policies that protect wildlife and their habitats.
Show Notes
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.
