Whale Communication Research
Discovery of Whale Songs
In the 1960s, military hydrophones accidentally picked up mysterious sounds later identified as humpback whale songs. Roger and Katie Payne helped share these sounds with the world through their 1970 album "Song of the Humpback Whale," a hit that spurred the environmental movement and new legislation like the Marine Mammal Act to protect whales.
New Insights on Sperm Whale "Codas"
Recently, MIT researchers used novel data visualization techniques to analyze sperm whale "codas" (vocalizations). They found sperm whales stretch, shorten, and ornament codas, suggesting a greater vocal repertoire than known.
Pratyusha Sharma speculates this could mean sperm whales have a language-like communication system, a revolutionary idea. However, scientists caution their communication may be fundamentally different from human language but still convey information like identity and group belonging.
New Data Collection Methods
To unravel whale communication's mysteries, researchers plan to collect billions of vocalizations using underwater drones and 24/7 acoustic monitoring. This data will fuel AI analysis.
Goal: Conversing with Whales
By creating artificial whale vocalizations and observing reactions, researchers hope to reach a level of understanding to predictably "converse" with whales, providing deeper insights into their cognitive and social dynamics.

Clarifications
- A hydrophone is an underwater microphone used to record or listen to sounds in water. It works based on a piezoelectric transducer that converts pressure changes, like sound waves, into electrical signals. Hydrophones are designed to match the acoustic properties of water for efficient underwater sound detection. They have been historically significant in various fields, including marine research and military applications.
- Sperm whale "codas" are specific patterns of vocalizations used by sperm whales for communication. Researchers have found that sperm whales modify these codas by stretching, shortening, and adding embellishments, indicating a complex vocal repertoire. This behavior suggests the possibility of a sophisticated communication system among sperm whales, potentially conveying information about identity and group affiliation. Scientists are exploring the idea that sperm whales may have a form of language-like communication that differs from human language but serves similar informational purposes.
Counterarguments
- The interpretation of sperm whale "codas" as a language-like system may be anthropomorphizing their communication, ascribing human characteristics to non-human entities without sufficient evidence.
- While the Paynes' album had a significant impact, it was one of many factors that influenced the environmental movement and legislation; other factors and individuals also played crucial roles.
- The goal of conversing with whales assumes that human-generated artificial vocalizations can be meaningful to whales, which may not align with how whales perceive and interpret sounds.
- The use of AI to analyze whale communication could introduce biases based on the algorithms and data used, potentially misrepresenting the complexity of whale communication.
- The collection of billions of vocalizations raises ethical concerns regarding the impact of increased human presence and technology in marine environments, which could disrupt whale habitats and behaviors.
- The assumption that we can predictably "converse" with whales may be overly optimistic, given the vast differences between human and whale cognition, social structures, and communication methods.

Recent breakthrough in understanding sperm whale communication
A collaborative effort between researchers from MIT and whale biologists studying sperm whales has led to a novel analysis of their unique vocalizations, dubbed "codas."
Scientists studied sperm whale vocalizations in a new way
MIT's researchers, through their innovative approach to data visualization, have shed new light on the complexity of sperm whale vocalizations.
Researchers from MIT used novel data visualization techniques to analyze sperm whale "codas" (vocalizations)
In the Caribbean, a computer science graduate student from MIT, Pratyusha Sharma, together with other researchers, decided to revisit recordings of sperm whale "codas." Sharma found the traditional method of analyzing whale songs, which relied on comparing visual audio recordings, to be unconvincing. She then flipped the images on their side, revealing previously unheard complexities in sperm whale vocalizations. Sharma’s technique showed that the whales produce a greater variety of sounds than was previously known.
This groundbreaking perspective allowed Sharma to observe that sperm whales play with their codas by stretching or shortening them. They sometimes add extra clicks, referred to as "ornamentations," to a repeated coda.
Implications of a potential "sperm whale language"
The new findings about sperm whale vocalizations may revolutionize what we know about animal communication and intelligence.
If sperm whales do have a language-like communication system, it would be revolutionary for our understanding of animal intelligence
The notion that sperm whales might communicate using a complex system akin to language is a thrilling possibility.
