Phylum: Mollusca, Class: Gastropoda, Order: Littorinimorpha, Family: Naticidae, Genus: Neverita, Species: Neverita duplicata · Naticidae (Moon Snail family) · Gastropod (snail/univalve), whole shell, spiral shape
Species
Neverita duplicata
Shell Type
Gastropod (snail/univalve), whole shell, spiral shape
Family
Naticidae (Moon Snail family)
Size
Approximately 0.5 inches in diameter, which is typical for a small specimen or juvenile. Adults of related moon snail species can range from 1 to 3 inches.
Color & Pattern
Glossy finish with a creamy beige to light brown base color, featuring faint brownish spiral banding and darker axial streaks. The colors appear natural and polished by wave action.
Rarity
Common, frequently found washed up on sandy beaches within its geographic range.
Habitat
Found primarily in shallow subtidal and intertidal zones, buried in sandy bottoms, mudflats, and shallow bays where they hunt for bivalve prey. Marine species.
Geographic Range
Western Atlantic coast from Massachusetts to the Gulf of Mexico and parts of the Caribbean.
Description
A smooth, compact, globose to depressed-spiral shell with a low spire and rounded whorls. The surface has a polished porcelain-like texture, showing subtle growth lines and muted brownish banding. The robust construction helps it withstand shifting sands and wave action in its native benthic environment.
Key Features
Low rounded spire, compact globular shape, smooth polished exterior surface, and typical naticid aperture configuration.
Collector Value
Low to moderate collector value. While common, polished specimens or unique color morphs are often kept by beginner beachcombers and shell enthusiasts. Typically valued at just a few dollars.
Condition Notes
Good condition with a smooth, intact surface and natural glossy finish. No major chips or structural damage detected, though it shows some signs of beach-wear.
Interesting Facts
Moon snails are famous predatory gastropods that drill perfectly round, bevel-edged holes into the shells of bivalves using an acidic secretion and their radula to feed on the soft tissue inside.
Ecological Role
Acts as an important carnivorous predator in benthic ecosystems, helping to control bivalve populations. They serve as food for various fish, birds, and larger marine predators.
Similar Species
Other moon snail species such as Euspira heros (Northern Moon Snail), which is generally larger and taller-spired, and Neverita lewisii (Lewis's Moon Snail), which is much larger.
Beach Finding Tips
Look along sandy beaches during low tide, particularly after storms or heavy surf. Sifting through shell lines and wet sand often reveals smaller moon snails and button shells.
