New renderings of the exterior of Qiddiya Oceanarium, which I think will be near Blue Planet, but not technically connected to or a part of Blue Planet:
SPECTOR in partnership with James Hampton Design of Melbourne, Australia, are currently in development is a 300,000 square foot oceanarium that will feature a variety of themed zones reminiscent of a theme park, offering visitors unique experiences such as a planetarium, a saltwater reef exhibit, a deep-water oceanarium, and a freshwater forest. Additionally, it will feature a central plaza or hub where people can recharge, socialize, and engage in educational activities, including dining options, school and university classes, and family picnics.
