Shell Type
Bivalve, whole single valve, fan to triangular shape
Family
Veneridae (Venus Clam family)
Size
Approximately 0.75 inches (about 2 cm), which is average for this species. Adults typically range from 0.75 to 1.5 inches.
Color & Pattern
Off-white to cream base color with subtle brownish or grayish banding and occasional darker speckles. The colors appear natural and slightly weathered.
Rarity
Common
Habitat
Found in shallow marine waters, typically in intertidal to shallow subtidal zones down to about 30 feet. Prefers sandy or muddy sand substrates, often near seagrass beds.
Geographic Range
Western Atlantic Ocean, ranging from North Carolina through the Gulf of Mexico, the Caribbean Sea, and down to Brazil.
Description
A charming, solid, triangular-ovate bivalve characterized by distinct grid-like or cancellated sculpture formed by prominent radial ribs intersecting with raised concentric lamellae. The margins are finely crenulated.
Key Features
Distinguished by the strong, box-like grid pattern created by the intersection of radial ribs and heavy, raised concentric growth ridges. The interior margin is finely toothed or crenulated.
Collector Value
Low to moderate commercial value. Very popular among casual beachcombers and beginner shell collectors due to its distinct, tactile texture, but too common for high-end specialist collections.
Condition Notes
Good condition single valve with some natural weathering and minor discoloration. The sculptural grid remains well-defined. Collectibility grade is Good.
Interesting Facts
Venus clams are burrowing bivalves that use a muscular foot to dig into sand. The prominent concentric ridges help anchor the shell securely in shifting sediment.
Ecological Role
Serves as an important prey item for carnivorous marine snails, rays, and bottom-feeding fish. As a filter feeder, it helps clean surrounding waters by consuming suspended microalgae and organic particles.
Similar Species
Other species in the genus Chione, such as the Smooth Chione (Chione elevata), which lacks the sharp grid-like texture of Chione cancellata.
Beach Finding Tips
Look along sandy or shelly beaches in the southeastern United States, particularly after storms or heavy wave action. Search the high-tide line where small shells accumulate.
