From Russia: A fish? A monster? An alien? A mermaid?

Yikes! Today in Global History my teacher somehow got on the subject of an "alien monster fish" found in Russia. So here is the story:

Some Russian fishermen were fishing in the Sea of Azov, and caught the strange looking "fish". The men first believed it to be a monster or an alien, which squeeked, and took video with a cell phone camera. Then they ate it! Specialists have looked at the video and say that the "fish" is not extraterrestrial, but have been unusure of the species. Some have said it looks like a skate, a member of the sting ray family, others say a sturgeon. The thing is preety strange looking and i was amazed while watching it. Here is the link:
