This one here is fake. This is the true comment given by the creature of the picture 

“I actually created this image to accomany an article about sea serpents that I wrote for a blog page a few years ago. It was never intended to appear ‘real’, just to be fun. Some people here have said that the mouth is ‘obviously’ fake.

The mouth and teeth are actually real, and part of the deep-sea fish that I incorporated into the original shot, which was of some fishermen pulling in a net. Some other people have said that the head is connected to a real log on the beach, but the whole body is drawn in. Still, I’m pleased that it seems to have interested quite a few people.”
