Nutmeg Snail (Common Nutmeg)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Cancellariidae, Genus: Cancellaria, Species: Cancellaria reticulata · Cancellariidae (Nutmeg family) · Gastropod (spiral shape, whole shell)
Species
Cancellaria reticulata
Shell Type
Gastropod (spiral shape, whole shell)
Family
Cancellariidae (Nutmeg family)
Size
Approximately 1 inch (25 mm) in length, which is average for this species. Adults typically range from 0.75 to 1.5 inches (20-38 mm).
Color & Pattern
Cream to light tan base color adorned with distinctive reddish-brown to dark brown spiral bands and axial markings. The surface features a characteristic crisscross or reticulated pattern resembling the texture of a grated nutmeg seed, giving the shell its common name.
Rarity
Common to Uncommon, frequently found by dedicated beachcombers or dredged by shrimpers in its native range.
Habitat
Found in shallow subtidal to moderately deep offshore waters, typically living on sandy or muddy bottoms, often buried in the substrate during the day.
Geographic Range
Western Atlantic Ocean, ranging from North Carolina through the Gulf of Mexico, Florida, the Caribbean, and south to Brazil.
Description
An attractive and robust small gastropod shell featuring a distinctively crossed-hatched or reticulated surface sculpture. It has a moderately elevated spire, rounded whorls, and a clear suture. The outer lip is slightly thickened and finely toothed on the interior, characteristic of the Cancellariidae family, leading to a short anterior canal.
Key Features
Strongly reticulated (grid-like) surface sculpture formed by the intersection of axial ribs and spiral cords; distinctive brown spotting and banding on a light background; presence of strong folds (columellar plaiting) on the inner lip.
Collector Value
Low to moderate value. While not a high-priced rarity, it is a staple for regional Atlantic and Caribbean collections due to its charming pattern and unique texture.
Condition Notes
The specimen appears to be in good, intact condition with natural coloration well-preserved, showing minimal wear on the apex and a clean exterior, grading as Fine to Good collectibility.
Interesting Facts
Members of the family Cancellariidae are known to be ectoparasites, specifically feeding on the body fluids of electric rays and other elasmobranchs using a specialized proboscis.
Ecological Role
Acts as a specialized parasite/predator on marine rays in its benthic habitat, contributing to the complex trophic webs of sandy and muddy coastal ecosystems.
Similar Species
Other cancellariids such as Cancellaria cooperi found on the Pacific coast, which is larger and has a different geographic distribution.
Beach Finding Tips
Best found by beachcombing after stormy weather along Gulf Coast and Florida beaches, or by examining shell hash in drift lines on sandy shores.
