Cross-barred Venus Clam (also known as the Little Cross-barred Venus)
Phylum: Mollusca, Class: Bivalvia, Order: Venerida, Family: Veneridae, Genus: Chione, Species: Chione cancellata · Veneridae (Venus Clam family) · Bivalve (two-shelled), whole individual valve with a fan-like to rounded-triangular shape.
Species
Chione cancellata
Shell Type
Bivalve (two-shelled), whole individual valve with a fan-like to rounded-triangular shape.
Family
Veneridae (Venus Clam family)
Size
Approximately 0.75 inches (19 mm) in length, which is a common size for a mature specimen. Adults typically range from 0.5 to 1.5 inches.
Color & Pattern
Cream to off-white base color featuring distinct, soft brownish-orange or tan bands radiating vertically and horizontally across the exterior. The interior appears glossy with subtle purplish or white tones.
Rarity
Common, frequently found intact along beaches in the Caribbean and southeastern United States.
Habitat
Inhabits shallow subtidal to intertidal zones, typically burrowing just beneath the surface in sandy or muddy substrates, often in seagrass beds or protected bays.
Geographic Range
Western Atlantic Ocean, ranging from North Carolina and Florida through the Gulf of Mexico, Caribbean Sea, and down to Brazil.
Description
A charming and sturdy small bivalve characterized by a deeply sculpted, grid-like pattern formed by prominent, raised concentric ridges intersecting with strong radial ribs. The margin is finely crenulated, and the overall shape is robust and slightly rounded.
Key Features
Distinctive cross-hatched or cancellate exterior sculpture created by the intersection of sharp radial ribs and raised concentric lamellae, along with a deeply impressed lunule near the umbo.
Collector Value
Low to moderate commercial value, but highly appreciated by amateur beachcombers and beginner conchologists due to its striking geometric texture and appealing miniature size.
Condition Notes
Good condition, showing slight natural wear around the margins but retaining crisp sculptural ribs and a clear, natural color pattern. Collectibility grade is Fine.
Interesting Facts
Venus clams are filter feeders that use specialized siphons to draw in water, extract microscopic algae and nutrients, and expel filtered water. Their tough, heavily ribbed shells provide strong evolutionary defense against crushing predators like crabs and fish.
Ecological Role
Plays an important role in benthic food webs as a filter feeder improving water clarity and serving as a prey source for bottom-feeding fish, rays, and carnivorous gastropods. Not currently endangered.
Similar Species
Chione pubera (Spotted Venus) or Chione intuspurpurea (Short Venus), which can be distinguished by differences in the spacing of the concentric ridges and interior coloration.
Beach Finding Tips
Look along high-tide shell lines on sandy beaches in Florida and the Caribbean, particularly after stormy weather or strong offshore winds when buried shells are churned up.
