In today's Huffington Post, there is a story entitled Exploring Exotic Deep-Sea Fish. Many of the fish I recognize are native to the reefs, which is NOT the deep sea and for reasons that are unclear, a few pictures were thrown in that are clearly hoaxes.
The article says this is called a frilled shark and it's one of those "living fossils", a species that has survived an incredibly long time. Obviously, this is a special effect from some cheezy movie on the Syfy channel. It was probably called something like SharkAcuda or AnacondaLamprey and starred either Larry Drake or F. Murray Abraham. I didn't see it, you didn't see it, and we are better off for the lack of experience.
C'mon, HuffPo! I didn't just fall off the turnip truck!
