Chicago might be far from any ocean, but that obstacle didn't stop it from pioneering the first permanent inland saltwater aquarium in the country. Civic leader John G. Shedd’s drive and contribution of $3 million paid for nearly a million gallons of seawater transported by rail from Florida’s coast, by 1930 the city hosted exhibits large enough to accommodate a wide variety of marine species–sea mammals as well as fish.

Today, Shedd’s dream continues to thrive with the aquarium’s scores of undersea creatures—from sharks and dolphins to vibrant sea cucumbers—showcased in educational, eye-catching exhibits. The permanent collection spirits visitors from the Great Lakes to the Amazon River to the waters of the Pacific Northwest. The resident animals often share their turf with seasonal exhibits like stingrays, who fill dramatic special exhibits.

The most exciting animal encounters, however, may come via the year-round Aquatic Presentation. Trainers may demonstrate the natural behaviors of sea lions, dolphins, and even beluga whales.
