That’s the saltwater side of the Shedd Aquarium’s new “Wonder of Water” centerpiece beneath its rotunda — part of $250 million worth of renovations, expected to be complete in 2027. It has replaced the Caribbean Reef, a living carousel of sea creatures — turtles, rays, bonnethead sharks and fish with scales like polished armor.

A massive new addition to the Shedd aquarium’s rotunda is making a splash. In the entrance of the Shedd Aquarium you’ll be greeted with two new towering habitats in the historic rotunda.

A new exhibit in the Shedd Aquarium's iconic rotunda space, featuring both fresh and saltwater ecosystems, will debut to the public on Tuesday.
