Curator's Corner

Museum, research, and collection updates from Dr. José H. Leal, plus Shell of the Week, which highlights a different species every Friday. Most Shells of the Week—but not all—are found in Southwest Florida.

Dr. José H. Leal serves as the Bailey-Matthews National Shell Museum’s Science Director and Curator. He received his Ph.D. in Marine Biology and Fisheries from the University of Miami and has served at the Museum since 1996. Under his leadership, the Museum was awarded its first accreditation from the American Alliance of Museums in 2010.

Shell of the Week: The Bleeding Tooth

Nerita peloronta Linnaeus, 1758, is a relatively common species on the rocky shores of the Caribbean and the East Coast of Florida. The Bleeding Tooth is a member of the nerite family (Neritidae) that may reach 50 mm (about two inches). Nerites are known to dissolve the internal part of the shell, including the central, pillar-like structure known as the columella. Shell dissolution affords extra space and allows the snail to retain a little water during low tides. And the co

One Nerite, or Two?

The introduction of DNA sequencing as a taxonomic tool in the 1980s started a revolution that keeps transforming the classification of mollusks and opening the way for better species delimitations. Molecular systematics has shown time after time not only that what we believe to be separate species are just one and the same, but also that what may be perceived as a single species may actually be two or more! Take, instance, the article by Cristiane Barroso, from the Universida

Shell of the Week: The Virgin Nerite

At 12 mm (about 0.5 inch), Vitta virginea (Linnaeus, 1758) is another small nerite with rounded, smooth shell. The parietal shield (the flat area inside aperture) is crescent-shaped, white, and may bear a number of small, irregular teeth. The shell is very variable in color; the dominant color may be black, red, green, purple, with spots, wavy or zigzag lines, and bands of alternating colors. The single shell of this species from Sanibel present in the Museum collection was c
