Goodbye to What We Thought About Whales – Bubble Rings Revealed as a Precise and Clever Hunting Technique

The ocean is full of mysteries, but sometimes, the most unexpected ones come from creatures we already know—like humpback whales.

Recently, scientists have observed something amazing: humpback whales creating perfect bubble rings only when humans are nearby. Seriously, they don’t do it when they’re alone or just among other whales. It’s like they’re performing a show just for us.

Coincidence? Communication? Play? Let’s cut into this surprising marine mystery.

Mystery

Imagine observing whales for days and noticing they keep doing the same thing—blowing perfect circular bubble rings that slowly rise to the surface like smoke rings from a cigar. These aren’t the typical hunting bubbles we already know about. They’re clean, artistic, and intentional.

That’s what led researchers from the SETI Institute and the University of California, Davis, along with the Marine Mammal Science journal, to investigate this strange phenomenon more closely. So far, they’ve documented 12 episodes involving 11 whales creating 39 rings—and all of it happened when humans were nearby.

Hunting

Now, whales using bubbles isn’t new.

Humpback whales are known for a feeding technique called bubble-net feeding, where they blow bubbles to trap schools of fish. But that method creates chaotic, foamy clouds of bubbles—not neat, circular rings. What scientists are seeing now is completely different.

These bubble rings are called poloidal vortices and are made with such precision that it’s hard not to think they serve a different purpose—especially because they’re being made outside of feeding time.

Behavior

Why would a whale make a bubble ring?

Well, whales and dolphins are known for being playful. They interact with objects, surf waves, and even play with each other in ways that seem purely for fun. So one theory is that these rings are just for play—a way to entertain themselves or maybe even us.

Another idea is that they’re trying to communicate. Humpbacks are famous for their haunting, complex songs, so it’s not a stretch to think they could be using bubbles to express something visually—especially toward humans.

It’s like a non-verbal language, one that we’re just starting to understand.

Humans

Here’s where it gets even more interesting.

Across over 5,000 drone observation flights, not one of these bubble rings was seen. But when humans are physically present, suddenly the bubble art begins.

Could it be that humans spark curiosity in whales? Or do they somehow inspire a kind of marine performance? We can’t say for sure, but the link is definitely there. The whales weren’t afraid, stressed, or trying to flee—they stayed nearby, calmly creating rings as if they were trying to show us something.

Precision

Making these bubble rings isn’t easy.

Whales form them using their blowhole, and they do it with no obvious effort. They rise gracefully to the surface in perfectly round shapes. It’s an incredible display of control and awareness, showing that these animals know their environment in ways we might not fully grasp yet.

It’s like they’re painting underwater… with air.

Meaning

So, what are these bubble rings really?

• A playful marine version of blowing bubbles for fun?
• A form of visual communication between whales and humans?
• Or perhaps, just another way these animals show off their intelligence?

Marine biologist Karen Pryor once suggested that bubble-making in cetaceans could be a unique form of communication, one that terrestrial mammals don’t have. And if that’s true, these bubble rings could be part of a language—one we haven’t learned to speak yet.

Whatever the reason, it opens a new window into animal behavior, intelligence, and the way humans and other species might connect in more subtle ways than we ever imagined.

So next time you’re on a boat or near the ocean, keep an eye out. You might just witness a humpback whale blowing a perfect bubble ring… just for you.
