Shell of the Week: The Costate Horn Snail
Cerithideopsis costata grows to 15 mm (about 0.6 inch). The shell may have around 12 round whorls and a sculpture of low, rounded axial ribs that decrease in size in the last two whorls, The outer lip is flaring in adult shells. The color is light- to dark-brown with spiral bands of lighter color. The species thrives around mangroves and protected areas of Southwest Florida and neighboring areas. The illustration represents a shell collected in March 1963 on North Captiva Island by William C. Brumbach. Cerithideopsis costata from NOrth…

The Green Mussel Pops Up Again!
During the latest Live Mollusk Count promoted by the National Shell Museum & Aquarium on March 11, organizer and Associate Director of Education Jorden Falker found two complete shells (paired valves) of the Green Mussel (Perna viridis). The shells, found at low tide on the east end of Sanibel Island, were discovered tangled in seaweed. The hinged shell and remnants of the soft bivalves’ bodies inside hint that the mussels died recently and came from a nearby location. Perna viridis shells from Lighthouse Beach, Sanibel, Florida.

The Floor Tiles at the Sanibel Community House
I have been intrigued by the new (post-Hurricane Ian), charming floor tiles at the entrance lobby of the Sanibel Community House (Sanibel, Florida). They are resin tiles with embedded shells deployed in cross-sections (see diagram on bottom image). The larger cross-sectional pieces clearly parade Queen Conch (Aliger gigas) attributes: The pink layer inside the aperture (shell opening), the large shell knobs, and the flared lip are all shell features of that majestic species. When on Sanibel, take a break to examine the SCH tiles and complement your visit by…
Shell of the Week: The Antilles Murex
Siratus articulatus is a shallow- to moderately deep-water Muricidae species living in the tropical western Atlantic, including the east coast of Florida, Florida Keys, and the Caribbean south to northeastern Brazil in depths between 16–400 m (about 52 to 1312 ft). Shells of this species can reach 95 mm (about 3.75 inches) in length, showing high degrees of variation in color and sculpture strength, in particular the size of spines and varices (the ridges that appear occasionally on the shell). The shell in this photo was collected off Sugarloaf Key…
Shell of the Week: The Cancellate Cone
Conus cancellatus reaches 80 mm (3.15 inches); its shell presents alternating narrower and wider spiral ridges. The color is very variable, from pure white to patterns of brown bands or spots. A periostracum (organic outer shell layer) may be light yellow to dark brown and may present rows of long hairs on the spiral ribs of the last shell whorl. The species has a very broad geographic range, living from the northern Gulf of Mexico, Florida, the Caribbean, through southern Brazil. Conus cancellatus for off Cape San Blas, Florida.
