Humpback whales have been seen blowing bubble rings towards humans, a behavior that researchers think might be playful or a way to communicate. This is the first time scientists have documented these whales creating stable bubble rings during friendly interactions with people, like when they approach swimmers or boats. The researchers believe these floating rings could represent a new form of expression from these intelligent creatures.
This discovery might even shed light on the search for intelligent life beyond Earth, as mentioned by the Search for Extraterrestrial Intelligence (SETI) Institute and scientists from the University of California. They published their findings in the journal Marine Mammal Science.
Are Humpback Whales Trying to Talk to Us?
Humpback whales are known to use bubbles in various ways, such as creating bubble nets to catch fish or trailing bubbles while competing for mates. However, the behavior of blowing bubble rings appears to be unrelated to feeding or competition. Instead, it reflects a sense of playfulness or a desire to connect with humans.
Dr. Fred Sharpe, a co-lead author of the study, points out, “Humpback whales live in complex social structures, are acoustically diverse, and use bubbles as tools. Now, we see they are blowing bubble rings toward us in an apparent attempt to engage with us.”
Researchers recorded 12 episodes involving 11 different whales from various populations. In each encounter, the whales approached humans and released a total of 39 bubble rings. Many of these whales showed a friendly curiosity, approaching boats and swimmers with bubbles.
Jodi Frediani, another co-lead author, highlights the whales’ inquisitive nature: “These whales often exhibit friendly behavior. We found a dozen individuals around the world that voluntarily interacted with boats and swimmers while blowing bubble rings.”
Implications for the Search for Extraterrestrial Life
This research is part of the WhaleSETI project, which investigates animal intelligence to improve methods for discovering extraterrestrial life. Understanding how humpback whales express curiosity may enhance our ability to identify signals from potential alien civilizations.
Dr. Laurance Doyle of the SETI Institute emphasizes that the way these whales evolve their curious behavior could inform our search for extraterrestrial intelligence: “Current technology assumes that alien life will want to make contact with us. This assumption gains support from the independent evolution of curiosity seen in humpback whales.”
Researchers hope that exploring non-human communication can refine our methods in the ongoing quest for extraterrestrial signals.

Final Thoughts
Humpback whales remind us of the intricate bonds in nature and the mysteries that still exist. Their playful behavior opens a window into understanding not just animal intelligence, but possibly the nature of intelligence beyond our planet.
