Angel Wing (often polished or carved as a sculpture/spoon)
Phylum: Mollusca, Class: Bivalvia, Order: Myida, Family: Pholadidae, Genus: Cyrtopleura, Species: Cyrtopleura costata · Pholadidae (Piddock family) · Bivalve (note: the image shows an artisan carved, polished, or modified shell piece, likely derived from a large bivalve or univalve structure given its twisted spiral/spoon-like shape)
Species
Cyrtopleura costata
Shell Type
Bivalve (note: the image shows an artisan carved, polished, or modified shell piece, likely derived from a large bivalve or univalve structure given its twisted spiral/spoon-like shape)
Family
Pholadidae (Piddock family)
Size
Approximately 4-6 inches in length. Standard Angel Wing shells typically range from 4 to 8 inches.
Color & Pattern
Uniform creamy white to pale peach with a polished, glossy finish, suggesting it has been buffed or crafted. Natural periostracum is entirely absent due to modification.
Rarity
Uncommon in natural pristine condition; this specific polished/carved form is a crafted curiosity rather than a standard beach find.
Habitat
Burrowers in heavy mud, clay, peat, or soft rock in the intertidal and shallow subtidal zones.
Geographic Range
Western Atlantic, from Massachusetts down through the Caribbean to Brazil, and the Gulf of Mexico.
Description
An elegantly elongated and twisted shell artifact featuring a smooth, glossy surface and an exaggerated spiral handle-like termination, demonstrating artisan craftsmanship.
Key Features
Elongated body, smooth polished surface, distinct twisted terminal end resembling a serving spoon.
Collector Value
Valued more as a decorative or curio item than a strict conchological specimen due to human alteration.
Condition Notes
Artisan-modified, highly polished, intact structure with no natural wear or fouling organisms visible. Collectibility grade: Crafted/Decorative.
Interesting Facts
Live Pholads bore into solid clay, soft rock, or wood using a rocking motion and microscopic ridges on their shells, creating permanent burrows where they live filter-feeding.
Ecological Role
Act as bioeroders by boring into coastal substrates, creating micro-habitats that other small marine organisms utilize after the piddock vacates.
Similar Species
Other boring bivalves such as Barnea truncata (Truncated Piddock), distinguished by lack of polishing and characteristic gaping valves.
Beach Finding Tips
Look for fragments of piddocks embedded in clay ledges exposed at extreme low tides, or search muddy salt marsh creek banks.
