There is a 12 million square-foot mall in Dubai, located directly in the shadow of the Dubai Burj, the world’s tallest building (for now). This massive mall has an impressive set of displays including a 33,000 specimen tank including an acrylic tunnel that people can walk through to view the aquatic specimens.

Things have gotten out of hand, however. In the tank the geniuses that put it together decided to include a group of very aggressive sand sharks that killed 40 smaller sharks on the first day. Divers performing maintenance have also been attached – although there have been no fatalities.
