A shark controversial?! really

Controversial would be one of the last words to come to mind when I look at these pieces. They make me think of how simple art can be, but how it takes a creative mind to take something like a shark preserved in formaldehyde into a piece of art. I look at art as art. I cannot decided if an artist's work is too controversial or not because the way I see art is completely different form anyone else's view. Interpretation of art can be completely opposite between two people. So if this is seen as controversial, then I feel like there will be a lot more controversial pieces in the future.
