After almost three years of planning, design, and fabrication, the central exhibits area of the Great Hall of Shells is open to the public. The Hall had been closed since Hurricane Ian made landfall on Sanibel in September 2002. Actual harm from the storm to the exhibits was negligible, but repair to water damage to the walls required removal of many exhibits. The time was ripe for much-needed renovation anyway. Executive Director Sam Ankerson decided to tackle the challenge head-on. Phase One of the Great Hall of Shells. Photo: José…

Calliostoma hendersoni reaches 23 mm (a little less than an inch) in diameter. As with many other deep-water species of top snails (family Calliostomatidae) from the western Atlantic, this one has a very elegant shell. The base has reddish-brown spiral lines against a cream-colored background, a narrow but deep umbilicus, and the spire presents a slightly concave profile in lateral view. Most distinctively, Henderson’s Top Snail has a series of relatively large spots along the shell periphery (the outermost shell “edge”). The species lives in moderately deep water: this specimen…
