A team of scientists from the SETI Institute, University of California Davis and the Alaska Whale Foundation, had a close encounter with a non-human (aquatic) intelligence. The Whale-SETI team has been studying humpback whale communication systems in an effort to develop intelligence filters for the search for extraterrestrial intelligence.
How long before whalers start playing the calls as bait?
Hopefully improving communication with whales will help shut down the last remnants of the whaling industry.
