Love these creatures, and I actually thought they were just fantasy for a long time! I like the Narwhal imperial stout and one time I noticed that the information about the animal on the bottle was written in such a way that you might think they're actually real so I looked online and was stunned to find out that as fantastical as they seem, they actually exist!
Haha, sounds like you were one of the lucky 10,000 that day
The realization that narwhals are real was a Mandela Effect[0] moment for me.
Even with a tag attached to a whale it is still impossible to be completely sure who made a sound. This is a big issue that has been haunting marine mammal communication research for decades. Hard to establish the function of the call when it is not clear who made it and who replied.
These are beautiful creatures, I even named my startup after them.
