On the very excellent blog BioFort, Scott Maruna's blog, is an item on the "alien" Russian fish. Er, alien. No, really, it's a fish. A guitarfish.
Weird looking creatures. I know I'd seen them somewhere, as I mentioned in the article on UFO Digest. I thought it might have been a skate; others think sturgeon. Sturgeon or pike always seem to be the explanation for weird things in the water; for Ogo Pogo, Champ, Nessie. That, or giant rotting salmon corpses, as in the case of Nessie. Yes, there really was a mega-skeptic that offered that theory to explain Nessie of Loch Ness.
