Humpback Whales Are Blowing ‘Bubble Rings' at Boats. Are They Trying to Communicate?
Humpback whales are known for their extensive use of bubbles—from powerful, aggressive bursts that prove their prowess during courtship to the bubble-net 'curtains' they produce to round up prey in a spectacle that often draws tourists from around the world. Now a new study published in Marine Mammal Science explores rare instances when humpbacks (Megaptera novaeangliae) create dramatic, doughnut-shaped vortex bubbles that look like a rolling underwater smoke ring. Video credit: Simon Hilbourne, Molly Gaughan, Karime Nicholas [Sign up for Today in Science, a free daily newsletter] Researchers at the University of California, Davis, and their colleagues at other institutions—including the SETI Institute, which is known for focusing on the search for extraterrestrial intelligence (SETI) but is also interested in nonhuman intelligences on Earth—were looking for examples of whales' general bubble behavior when they uncovered a striking video taken by videographer Dan Knaub in 1988. In the footage, a humpback called 'Thorn' blows 19 bubble structures—including 11 rings—over a 10-minute period. 'We were just gobsmacked—like, 'What the hell is going on?'' says Fred Sharpe, a whale biologist at U.C. Davis. 'For a team that's interested in assisting astrobiologists parse unusual signals coming from deep space, it just fell real neatly into our paradigm.... It's so bizarre.' Sharpe and his colleagues soon found more examples on social media and from other researchers. Study co-author Jodi Frediani, a wildlife photographer who is also at U.C. Davis, even noticed a telltale circle in a photograph a friend showed during a presentation about humpback whales. With this phenomenon on her mind, she says, 'I went, 'Gee, there's a bubble ring!'' For the study, the team recorded 12 events across the North and South Pacific and North Atlantic Oceans in which 11 individual humpbacks were seen blowing bubble rings. The researchers described 39 rings in total. 'It's not a lot in the world of whales but enough—and in multiple oceans,' Frediani says. 'It's a really fun paper,' says Syracuse University biologist Susan E. Parks, who studies bubble-net feeding in humpbacks and wasn't involved in the new study. 'It reads like a detective story that's trying to piece together information about something that's not widely studied and happens rarely.' Parks hasn't observed any bubble rings herself—as far as she knows, she says, 'I may have seen them before and never really thought anything of them.' Despite compiling so many examples of the rings, Sharpe still doesn't know what to think about their purpose. 'My guess is that this is what it's going to feel like when we first make contact with aliens,' he says. The researchers speculate that the behavior could be playful. One whale would blow a bubble ring and then swim through it or 'do a spy hop right through the middle of it,' Frediani says—when performing such a spy hop, the whale would peep its head vertically above the surface, right through the bubble ring. Or perhaps the animals' behavior could respresent curiosity toward humans: of the 12 recorded events, nine involved whales that approached the human observers more closely before they blew rings. Humpback communication quote Could the whales be trying to communicate with us? Sharpe doesn't rule this out as a possibility. He posits that the presence of humans seems to trigger bubble blowing and that humpbacks improve with practice. 'This may be a species-atypical signal that's crafted for people,' he says, 'whales reaching out to humans ... using their own parlance, their own form of communication.' Parks thinks it's plausible that the animals are putting on a display for humans, but she adds that it's too soon to tell with such a small sample size. 'They'd want a lot more [observations] before they could say with certainty,' she says. Because most of the observations were made by people, this could skew the data, she notes, although there were 'two observations from planes, so we know [the whales] do produce them [bubble rings] when people aren't present, too.' Now that more researchers know to look for these bubble rings, Parks says, reported sightings may greatly increase. With more data, Sharpe and his colleagues hope to figure out what the purpose of these swirling doughnuts of air is—and whether the rings could possibly contain information. 'We need the entire human brain trust's help deciphering this,' Sharpe says. 'It's almost like [the whales'] blowhole is a mouth, and the symbols coming out are bubbles, as opposed to sounds.' Sharpe hopes footage from the study will help people feel connected with whales and make them want to protect the animals from human threats such as ship strikes, entanglement, noise and chemical pollution, habitat loss and disruption of the food web. He says that he also wants to find a way to let the whales 'know that they've been heard.' For him, trying to decipher potential messages and find a way to respond puts the team 'in the same place you would be if you were trying to communicate with aliens—and you got a message.'

Humpback whales could be secretly trying to talk to humans, scientists say
Humpback whales have been documented for the first time creating large bubble rings in water during friendly interactions with humans, suggesting they could be trying to communicate with us. The whales are known to use bubbles to hunt prey and when competing to escort females. They don't just produce these rings but also manipulate them in a variety of ways, actively controlling their size and depth. A new study, published in Marine Mammal Science, hints that they could be trying to communicate with humans using the bubbles during friendly encounters. ' This important assumption is certainly supported by the independent evolution of curious behaviour in humpback whales,' said Laurance Doyle, an author of the study from SETI Institute. Researchers have previously documented the whales living in complex societies and using their ring bubbles to assist other species harassed by predators. The bubble rings are described by researchers as spinning, air-infused vortices that look like 'giant smoke rings' about a metre in diameter. The whales often exhibit inquisitive, friendly behaviour towards boats and human swimmers. "Now, akin to a candidate signal, we show they are blowing bubble rings in our direction in an apparent attempt to playfully interact, observe our response, and/or engage in some form of communication,' study co-author Fred Sharpe said. "We've now located a dozen whales from populations around the world, the majority of which have voluntarily approached boats and swimmers blowing bubble rings during these episodes of curious behaviour,' said Jodi Frediani, another author of the study, In the study, researchers analysed 12 humpback whale bubble ring production incidents, totalling 39 rings made by 11 individuals. They categorised the whales into known age classes: yearling; 4-6 years old subadult; and adult. In many of these instances, during ring release, the whales were motionless or slowly idling forward 'with blowholes held upright and the body mostly in the horizontal position'. 'None of the other ten episodes were associated with feeding behaviour nor were prey organisms noted within rings,' the researchers noted. They also confirmed that none of the observed whales expressed any aggressive behaviour towards a boat or a human swimmer. In a majority of the observed incidents the ring blowing whale was alone, suggesting that the intended recipient wasn't another whale. 'Ring generation during inquisitive encounters adds to the humpback whale's diverse interspecies behaviours,' the scientists wrote. The findings are also intriguing since researchers believe interacting with the humpbacks can be a proxy for communicating with aliens. Studying these whale interactions can offer valuable insights into non-human intelligence and potentially help refine methods for detecting extraterrestrial life, scientists say. 'More research is needed to systematically study bubble ring production and ascertain under what conditions bubble rings are consistently produced,' they said.

Humpback whales may blow bubble rings to say hi to humans
Humpback whales are known for being pretty smart mammals, and researchers have made a discovery that may tell us even more about them. A team of scientists from the SETI Institute and the University of California at Davis have documented humpback whales blowing large bubble rings when interacting with people for the first believe it could be a way in which the whales greet humans, representing either play or communication. Humpback whales blowing bubbles has been seen before, mainly when they're either tracking down their prey or competing for the attention of a female the latest discovery suggests the mammals' bubble rings, which they make by forcing air through their blowholes and mouths, could also be used when it comes to encounters with humans. "We show they are blowing bubble rings in our direction in an apparent attempt to playfully interact, observe our response, and/or engage in some form of communication," said Dr. Fred Sharpe who is a co-lead author on the study which was published in in the journal Marine Mammal part of their research, the team looked at 12 separate instances of bubble production involving 39 rings made by 11 different whales. Out of the twelve episodes reported, ten were collected near a boat or near human swimmers, with eight of the bubble ring blowers actually coming closer. Six of the episodes had more than one whale present and there was no sign of annoyance or aggressive behaviour towards the boats or humans in any of them. "Humpback whales often exhibit inquisitive, friendly behaviour towards boats and human swimmers," said co-lead author Jodi Frediani who is a marine wildlife photographer. "We've now located a dozen whales from populations around the world, the majority of which have voluntarily approached boats and swimmers, blowing bubble rings during these episodes of curious behaviour."

How humpback whales are playfully communicating with humans, according to scientists
Humpback whales may be communicating with humans in a playful way, according to researchers who have been studying the marine mammals' behavior. Researchers from the SETI Institute, a Silicon Valley-based nonprofit research organization, documented humpback whales producing large bubble rings -- similar to the rings humans can produce while blowing smoke -- during friendly interactions with humans, they noted in a paper published last month in the journal Marine Mammal Science.

Humpback whales were already known to use bubbles to corral, and males have been observed creating bubble trails or bursts when competing for a female mate, according to the SETI Institute. But new observations that appear to show humpback whales producing bubble rings during friendly encounters with humans contributes to a broader goal of studying non-human intelligence, the scientists said. Studying non-human intelligence can aid in the search for extraterrestrial life, the researchers said. The SETI whale team is aiming to develop filters that aid in parsing cosmic signals for signs of extraterrestrial life by studying intelligent, non-terrestrial -- or aquatic -- nonhuman communication systems, according to the research organization. "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," Laurance Doyle, SETI Institute scientist and co-author on the paper, said in a statement. "This important assumption is certainly supported by the independent evolution of curious behavior in humpback whales." Researchers analyzed 12 bubble ring–production episodes involving 39 rings made by 11 individual whales, they said. They determined the whales are blowing bubble rings in the direction of humans in an apparent attempt to playfully interact, observe humans' response and engage in some form of communication, Fred Sharpe, a co-author of the paper, said in a statement.
