July 17th, 2012. This rocky, landscaped habitat features 4 beluga whales in a 750,000 gallon pool and a trio of 20-foot long underwater viewing windows. There are conifers in the background, a pile of logs at the shallow end of the exhibit, caves with bubble-shaped windows and a trio of pools in an area that covers an acre in size. There are many vantage points, including underwater viewing, and the pool and its white whales is obviously the star attraction of the entire aquarium.
