After the “orca uprising” captivated anti-capitalists around the world in 2023, scientists are intrigued by another form of marine mammal communication.
A study released this month by the SETI Institute and the University of California at Davis dives into a newly documented phenomenon of humpback whales blowing bubble rings while interacting with humans. In contrast to the orcas’ aggressive behavior, researchers say the humpbacks appear to be friendly, relaxed, and even curious.
Bubbles aren’t new to these aquatic giants, which typically release various shapes when corraling prey and courting mates. This study follows 12 distinct incidents involving 11 whales producing 39 rings, most of which have approached boats near Hawaii, the Dominican Republic, Mo’orea, and the U.S. Atlantic coast on their own.
The impact of this research reaches far beyond the oceans, though. Deciphering these non-verbal messages could aid in potential extraterrestrial communication, as they can help to “develop filters that aid in parsing cosmic signals for signs of extraterrestrial life,” a statement says.
“Because of current limitations on technology, an important assumption of the search for extraterrestrial intelligence is that extraterrestrial intelligence and life will be interested in making contact and so target human receivers,” said Dr. Laurance Doyle, a SETI Institute scientist who co-wrote the paper. “This important assumption is certainly supported by the independent evolution of curious behavior in humpback whales.” (via PetaPixel)
