Real Mermaids # 7
This is a classic example of something that people want to be real so badly that they will likely believe anything that people tell them that supports it. Case in point, Animal Planet aired a mockumentary last year that upset many, as it was cleverly presented in a way that made it seem real. The fact is that science does not support the idea that a real mermaid, at least in the traditional sense could exist. But the ocean is a bit place, so who knows?
