As others have replied to David Brown's question, this is the new aquarium that is adjacent to the (grossly overpriced) butterfly place in Scottsdale.
As someone else pointed out, it is also adjacent to the upcoming swim with dolphin place, which has its own thread and our active forum member from Mexico points out is run by a Mexican company that on outward appearance does not seem to have the highest standards of zoo professionalism (that is how I read his statement).
Apparently I vastly underestimated the size and scope of this project. I am shocked to learn that it is well within the top ten in the country in terms of size.
That being said, the photo link above (26 photos total) do not leave me at all impressed. It seems most of the space is open floor and the exhibits (based on these photos) are very bland. There is nothing in that photo essay that makes me want to visit.
Arizona and the southwest are in a long term serious drought and I question the validity of opening an attraction that uses huge amounts of water in the desert.
So if you feel it is the duty of a local Zoochatter to visit and post a report, I suggest you look to Azcheetah2, as she lives closer than I do anyway.
