They teamed up and spoke to a humpback whale named Twain. They spoke to her in "humpback language" for 20 minutes. The scientists sent a "contact call" into the ocean off the coast of Alaska.

Each time, Twain responded by calling back at the same intervals. A scientist told the Business Insider website that the research could make it easier to talk to (6). She said: "There are diverse intelligences on this planet. By studying them, we can better understand what an alien intelligence might be like because they are not going to be exactly like ours."
