Shedd Aquarium (John G. Shedd Aquarium) — Chicago public aquarium

Collections and habitats

Shedd houses a large and diverse living collection that has included tens of thousands of individual animals representing roughly 1,500 species. The collections span freshwater and marine fishes, invertebrates, amphibians, reptiles, birds, and marine mammals. Exhibits are organized to reflect major aquatic environments, with galleries that simulate coral reefs, tropical rivers, the Caribbean and Pacific seas, and the open ocean. Large tanks, touch exhibits and enclosed habitats are designed to provide welfare-appropriate care and to illustrate ecological relationships.

Permanent and special exhibitions

The aquarium combines long-term galleries with rotating and seasonal exhibits. Permanent galleries have focused on freshwater ecosystems such as the Amazon and Great Lakes, reef systems populated by colorful fishes and invertebrates, and habitats for marine mammals. Special exhibits have presented immersive themes and new interpretive approaches; several have been recognized by professional organizations for design and educational impact. Visitors can experience feeding demonstrations, animal-training sessions, and interpretive talks throughout the day.

• Amazon and freshwater river habitats — species adapted to riverine conditions and seasonal floodplain cycles.
• Coral reef and tropical marine galleries — reef fishes, corals and associated invertebrates.
• Marine-mammal habitats and performance spaces — where applicable, used for public education about pinnipeds and cetaceans.

History, architecture and development

Since its opening in 1930, Shedd Aquarium has been an important cultural and scientific institution in the United States Midwest. For many decades it was the largest indoor aquarium by water volume until larger modern facilities opened elsewhere, notably the Georgia Aquarium in 2005. Over time the institution has modernized its exhibits, updated animal-care standards and expanded its educational offerings while preserving the historic character of the original building and site in downtown Chicago, Illinois.

Conservation, research and education

Beyond public display, Shedd engages in conservation initiatives and research partnerships focused on aquatic ecosystems and species conservation. Programs include captive-breeding efforts for vulnerable species, water-quality research, and outreach to schools and community groups. Educational programming ranges from school visits and camps to behind-the-scenes tours and adult learning events, all designed to promote stewardship of aquatic environments and to make science accessible to diverse audiences.

Visitation and public role

The aquarium routinely attracts around two million visitors a year and has been cited as one of Chicago's most popular cultural attractions. Its lakeside location and proximity to other Museum Campus institutions make it a frequent stop for tourists and local families. Accessibility services, seasonal programming, and special events aim to welcome a broad public while communicating conservation messages and research findings.

Awards and distinctions

Shedd has received recognition for exhibit design and education from professional associations. Its historical role as an inland aquarium with a long-term saltwater collection and its continuing work in animal care, interpretation and conservation contribute to its reputation. The aquarium balances public engagement, scientific inquiry and stewardship in its ongoing mission.

For up-to-date information on hours, tickets and current exhibits, visitors are encouraged to consult official institutional resources and partner information pages prior to visiting. The Shedd Aquarium remains a significant cultural and scientific landmark on Chicago's lakefront, linking public education with active conservation work.
