STRANGE see through fish :
This may possibly be the strangest thing that I have ever seen in my entire life. I was looking through posts, while my fiancee watched football and all of sudden I start freaking out, about a see through fish that you can see its brain. He had no clue what I was talking about and then he saw it. We were both kind of in shock.
This is the barreleye deepwater fish. The fluid in its head enables it to move its eyes.
