The junonia is among the hardest shells to find along Florida’s beaches, but visitors can reliably see one at Sanibel’s National Shell Museum & Aquarium.

The Sanibel museum has a vast collection of junonia shells, offering a dependable alternative to the beachcombing luck usually needed to spot the prized shell in the wild.

Sanibel, a barrier island on Florida’s Gulf Coast, is closely associated with shelling. For visitors hoping to learn more about the shells that draw beachcombers to the island, the museum and aquarium’s collection provides an indoor stop centered on that distinctive find.
