We went to the Aquarium Wednesday partly to celebrate our second Vegas anniversary. It is a preview exhibit and the plans they have for the finished product are really cool including a large rotating globe with the surface showing real time satellite images. They had an octopus which was probably our favorite thing to see. The pictures don't show it very well. We found out that Octopuses only have a lifespan of about 5 years, which I was surprised by. They also had some seahorses, which I thought were adorable. And we were able to pet some sting rays (without stingers). They were soft and velvety except for the hard spines on their backs.
