Mola's are such a crazy fish. I've never heard them called Oregon Sunfish, they're found all over the world. They eat almost exclusively jellyfish, which is nuts considering how poor a diet jellyfish are, and they're also the heaviest known bony fish. The one in the video is pretty small still! They don't have a caudal (tail fin) at all. Their spine just ends after 12 vertebrae. I think they also produce more eggs than any other vertebrate, up to 300 million PER spawn.
That's pretty much all I remember about them. Cool find!
