Whale experts and alien hunters have come together and have successfully exchanged conversations with the aquatic mammals.
In a study published last month in the peer-reviewed journal PeerJ, scientists from UC Davis, the Alaska Whale Foundation, and SETI (Search for Extraterrestrial Intelligence) teamed up and unveiled how they had a 20-minute conversation with a humpback whale named Twain in her own language.
Highlights
- Scientists from UC Davis, Alaska Whale Foundation, and SETI had a 20-minute conversation with a humpback whale named Twain in her own language.
- Twain responded 36 times to 'contact calls' played by the team, matching the intervals between calls, suggesting intentional exchange.
- This study marks the first communicative exchange in humpback 'language' between humans and whales.
The scientists sailed a boat off the coast of Alaska and played what's called a "contact call" into the ocean to see if any whales would respond, Science Alert reported.

Brenda McCowan, a professor at UC Davis's School of Veterinary Medicine, explained that contact calls are similar to a human greeting in that whales use them to call over other whales or let each other know where they are.
Fred Sharpe, co-author and principal investigator with the Alaska Whale Foundation, said: "They are one of the most common signals within the humpback whale social sound repertoire.”
Twain reportedly swam up to the scientists’ boat and circled it. For the next 20 minutes, the team emitted the same contact call 36 different times at varying intervals, and Twain responded to the call each time, even closely matching the intervals.

The result reportedly suggests that if the scientists waited 10 seconds before playing a call back to Twain, she would in turn wait 10 seconds before responding, Brenda explained.
This type of interval matching also reportedly suggests Twain was engaged in an intentional exchange. Fred told Business Insider: "It certainly felt like we had been heard. And we hope that she felt the same way, too.”
The whale expert highlighted that their work was done with a permit from the National Marine Fisheries Service and warned readers should not try this on their own.

In a statement for the SETI Institute, Brenda said: “We believe this is the first such communicative exchange between humans and humpback whales in the humpback 'language’.”
The calls came from humpback whales the researchers had reportedly recorded from a small group of whales just the day before their encounter. The group had included Twain, so it's possible Twain was responding to her own signal.
In the same statement, Fred said: “Humpback whales are extremely intelligent, have complex social systems, make tools - nets out of bubbles to catch fish - and communicate extensively with both songs and social calls.”

Subsequently, Twain's responses could potentially be linked to how intelligent alien races may seek humanity out.
Laurence Doyle, a principal investigator at the SETI Institute and coauthor on the paper, said: “Because of current limitations on technology, an important assumption of the search for extraterrestrial intelligence is that extraterrestrials will be interested in making contact and so target human receivers.
“This important assumption is certainly supported by the behavior of humpback whales.”
Laurence and his colleagues at SETI are reportedly working with whale and animal experts at UC Davis and the Alaska Whale Foundation to create intelligent filters to aid in their search for extraterrestrial intelligence, as per Science Alert.

He told Business Insider that if extraterrestrials are out there, sending us signals, trying to communicate, we might miss them if we don't know what to look for.
If significant improvements are made to these intelligent filters, scientists could reportedly use them to identify intelligent signals from space in an attempt to make first contact with an alien race.

Brenda told Business Insider: "There are diverse intelligences on this planet, and by studying them, we can better understand what an alien intelligence might be like because they're not going to be exactly like ours.”
The research is also testing the hypothesis of whether or not intelligent alien life would even seek us out. Laurence further explained: "Whale research has indicated if you're intelligent, curiosity comes along with that, and you want to make contact.”
Many people believed that other species could communicate with us
