Pacific Dove Shell or similar Columbellid (Dove Snail)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Columbellidae, Genus: Alia, Species: Alia carinata · Columbellidae (Dove snail family) · Gastropod (univalve snail), whole shell, fusiform to elongate-ovate shape
Species
Alia carinata (Keeled Dove Snail) or related Columbellidae species
Shell Type
Gastropod (univalve snail), whole shell, fusiform to elongate-ovate shape
Family
Columbellidae (Dove snail family)
Size
Approximately 12 mm in length, which is typical for adult dove snails in this region. Species within this family generally range from 5 mm to 25 mm.
Color & Pattern
Pale whitish-cream base color with distinctive pale grayish-blue or lavender banding on the spire whorls. The suture features a characteristic beaded or finely nodulose cord. The surface has a glossy finish with subtle growth lines.
Rarity
Common to Very Common. These small snails are frequently found by beachcombers examining driftlines and tide pools along the Southern California coast.
Habitat
Found in shallow intertidal and subtidal zones, commonly associated with rocky shores, tide pools, kelp forests, and seagrass beds where they graze on microalgae and detritus. Marine environment.
Geographic Range
Eastern Pacific Ocean, ranging from Alaska down to Baja California, Mexico, including the coast of Southern California (San Diego).
Description
A charming, small marine gastropod featuring an elongated, fusiform shape with a pointed spire and a smooth, glossy exterior. The whorls are distinctly ornamented with a finely beaded band directly below the sutures. The aperture is narrow with a slightly thickened outer lip, terminating in a short anterior canal.
Key Features
Small size, elongated fusiform profile, glossy finish, and distinctive beaded sutural cord accompanied by faint grayish or brownish banding on the spire whorls.
Collector Value
Low to Moderate commercial value, mostly valued by local micro-shell collectors and educational displays. Typically not sold at high prices, but appreciated for intricate patterns under magnification.
Condition Notes
Good to Fine condition. The shell is fully intact with no major fractures or deep chips, retaining much of its natural glossy luster and subtle banding, though minor natural wear is visible on the apex.
Interesting Facts
Dove snails are remarkably active for their size, moving rapidly across rocks and algae on a muscular foot. Despite their tiny size, they play an important grazing role in microalgae management within tide pool ecosystems.
Ecological Role
Primary consumers that graze on diatoms, microalgae, and organic films on rocks and vegetation. They serve as a vital food source for small fish, crabs, and carnivorous micro-gastropods.
Similar Species
Other members of the Columbellidae family, such as Amphissa columbiana (Wrinkled Dovesnail), which features stronger axial ribs rather than a smooth body whorl with a beaded suture.
Beach Finding Tips
Look in shell drift, among fine gravel, or sift through seaweed deposits washed up on Southern California beaches, particularly around low tide in protected coves or rocky intertidal areas.
