Humpback Whales Blowing Giant Bubble Rings: A Form of Communication?
A recent study suggests that humpback whales blowing giant bubble rings underwater may be attempting some form of communication with human onlookers. These majestic creatures, scientifically known as Megaptera novaeangliae, are renowned for their spiral bubble nets used for hunting. However, not all bubbles created by whales serve the same purpose; some are playful, some frisky, and others aggressive.
The unique bubble-blowing behavior observed in the study involved humpback whales producing perfect circles resembling “giant smoke rings about three feet in diameter that rise rapidly to the surface,” as described by biologist Roger Payne.

An international team of biologists and photographers analyzed videos and photos of whales producing bubble rings from various perspectives, both underwater and above the surface, to understand the context of this behavior.

The data collected included 39 bubble rings generated by 11 humpback whales, with most instances occurring near boats or human swimmers. Surprisingly, there was no evidence of aggression towards conspecifics or humans during these interactions.
Whales have exhibited playful behavior near vessels in the past, suggesting intentional engagement with humans. While the idea of whale-to-human communication is intriguing, further research is needed to decipher the true purpose behind these bubble rings.
The researchers emphasize the importance of continued observation to unravel the potential communicative aspect of these bubble rings and their significance in interspecies interactions.
The study is published in Marine Mammal Science.
