The more we learn about whales, the more their sounds appear to be intelligent communication. Language, complete with dialects that help them identify their own pod.
And it makes me wonder if maybe they’re even more advanced than we think. Maybe they have their own culture — pop culture, philosophy, legends, religion.
I really, really like to think that some of them have a story about a whale who defied their whale god, and as a punishment, when he took a big mouthful of krill or whatever during a storm, he ended up swallowing a dude who made him sick to his stomach until he relented and promised to obey and the whale god caused him to vomit the guy up on a beach.
That would be awesome.
