Sanibel Island's orientation causes it to act as a 'scoop,' collecting more shells from the Caribbean than almost anywhere else in the Gulf of Mexico.
The museum collection contains over 500,000 shells, though only a fraction is displayed at any given time.
The aquarium wing houses the 'Giant Pacific Octopus,' one of the most intelligent invertebrates in the world.
Many of the shells on display were donated by amateur collectors, including some from the personal collections of dedicated malacologists.
The museum functions as a center for research, often collaborating with universities to study the health of the local marine ecosystem.
The Bailey-Matthews National Shell Museum & Aquarium is the only museum in the United States devoted exclusively to shells and mollusks. It houses a massive collection of shells from around the world and features a significant aquarium wing showcasing live mollusks. The museum includes the 'Beyond Shells' exhibit, which explores mollusk biology, ecology, and their role in human history. Children can participate in hands-on activities in the dedicated learning labs and interactive play areas. The aquarium wing features tanks with cold and warm water species, including octopuses, cuttlefish, and various bivalves. It is located on Sanibel Island, an area globally recognized for its unique shell-collecting beaches. Visitors can view rare, record-holding, and artistically significant specimens across two floors of galleries.

Visit the touch pool area early in your trip to get a tactile introduction to live mollusks before exploring the static shell exhibits.
Ask the museum staff about the current 'Shell of the Month' to learn about specific rare specimens currently on display.
Combine your visit with beachcombing at the nearby 'Sanibel Stoop' locations to practice identifying shells you found in the wild.
Do not attempt to collect live shells from the beach; it is illegal in Florida to take any shell containing a living creature.
Maintain quiet voices in the aquarium galleries; do not tap on the glass of the tanks.
