Looks like a cartoon video.
I'd love to believe it's real, but I'm skeptical as hell....
If you look at things underwater, things are grey and green and dull colors. Then when you hit it with a bright light, the colors are shockingly bright and neon, amazing
Maybe it’s the fish’s bitmoji?
I recall watching some video where some oceanographer was talking about how they use the old submarine listening devices (from the cold war) and now use them to listen to whales.
The scientist is playing clips of the various sounds. “That is a humpback off the coast of Alaska; this one is a sperm whale off of California. Etc.
Then he plays one that sounds part animal, part electronic. Like a Grade B sci-fy film noise of the alien flying saucer.
“That is from 5 miles down in the Marianas Trench. We have do idea what that is from.”
I've tried to find the video again over the years with no luck.
