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.

The new entrance exhibit in place of the former Caribbean Reef is part an ongoing renovation leading up to the aquarium’s centennial in 2030.

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

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.
