Tulip Snail (specifically the True Tulip)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Fasciolariidae, Genus: Fasciolaria, Species: Fasciolaria tulipa · Fasciolariidae (Tulip and Spindle Snail family) · Gastropod (univalve); Fragment of the body whorl
Species
Fasciolaria tulipa
Shell Type
Gastropod (univalve); Fragment of the body whorl
Family
Fasciolariidae (Tulip and Spindle Snail family)
Size
The fragment is approximately 1.5 to 2 inches long. This likely came from a moderately sized adult shell, which typically reaches 4 to 8 inches in total length.
Color & Pattern
Base color is a reddish-brown to mahogany hue. It features the diagnostic pattern of fine, dark brown or black spiral lines (interrupted dashing). The surface has a slightly glossy finish indicating some preservation of the natural enamel despite erosion.
Rarity
Common (Whole specimens are found with some searching; beach-worn fragments like this are very common on South Carolina beaches).
Habitat
Typically found in shallow subtidal waters, often in seagrass beds (Thalassia), sand flats, and coral reef lagoons at depths from 0 to 30 meters.
Geographic Range
Western Atlantic, ranging from North Carolina down through Florida, the Gulf of Mexico, the Caribbean, and south to Brazil.
Description
This is a body whorl fragment of a True Tulip shell. It displays the classic fusiform curvature and smooth texture characteristic of the species. The exterior is marked by distinct, closely spaced dark spiral lines that resemble handwriting or fine stitching against a warm brown background.
Key Features
Smooth shell surface (unlike the Banded Tulip which has ridges near the suture); distinct dark spiral lines; deep mahogany/brown coloration typical of the Northern variety found in the Carolinas.
Collector Value
Minimal for a fragment, but highly desirable as a whole shell. In South Carolina, finding a large, unbroken True Tulip is considered a significant find for local beachcombers.
Condition Notes
Fragmentary/Poor. This is a partial piece of the main body whorl, likely broken by surf action or a predator (such as a crab). It shows significant wave-wear at the edges and some calcium deposits/pitting.
Interesting Facts
The Tulip snail is a formidable predator that eats other mollusks, including other Tulips and even the larger Queen Conch. They are known for being more active and 'aggressive' than many other slow-moving snails.
Ecological Role
An important apex predator in the benthic community, helping to regulate the populations of other gastropods and bivalves. It is not currently protected or endangered.
Similar Species
Cinctura hunteria (Banded Tulip), which is smaller, paler, and has fewer, more widely spaced spiral lines with distinct ridges near the top of each whorl.
Beach Finding Tips
In Myrtle Beach, look in the 'shell wash' after a strong storm or during extreme low tides. Look for the distinctive dark 'stitch' lines amidst the gray and white fragments of clams.
Notes
Found in Myrtle Beach in SC. It’s a broken piece of a shell, not a full shell
