If the movie Arrival suggests anything, it’s that communication with other species will have a different language. Whales may be communicating with humans.
Researchers at the SETI Institute and UC Davis have documented a striking new behavior in humpback whales. These whales, some weighing over 30 tons, are seen producing nearly perfect rings of bubbles that spiral to the surface. These aren’t random puffs. The whales often blow them during close encounters with humans and they seem to be watching what we do next.
