Approximately 0.2 to 0.3 inches (5-8 mm), which is typical for this miniature species.
Color & Pattern
Whitish to cream-colored base with characteristic zigzag or crescent-shaped brownish markings. The colors appear somewhat sun-bleached and worn.
Rarity
Common, though easily overlooked due to its tiny size.
Habitat
Shallow subtidal and intertidal zones, often found among algae, seagrass beds, and under rocks on sandy or muddy bottoms.
Geographic Range
Western Atlantic from Nova Scotia, Canada, down to Florida, the Gulf of Mexico, and the Caribbean.
Description
A charming, diminutive high-spired gastropod with a smooth, polished exterior. It features a narrow aperture and a subtle outer lip, showcasing intricate zig-zag patterns typical of the species.
Key Features
Small size, smooth glossy finish, high spire relative to body whorl, and distinct zig-zag or crescent brown markings on a pale background.
Collector Value
Low commercial value due to abundance and tiny size, but popular among micro-shell collectors and beachcombers making crafts.
Condition Notes
Fair condition; weathered and sun-bleached with a small hole in the body whorl likely caused by a predatory snail or natural erosion.
Interesting Facts
Dove snails are active scavengers and micro-grazers, often gliding rapidly over algal surfaces in search of detritus and diatoms.
Ecological Role
Serves as an important micro-grazer controlling algal growth and forms a vital food source for small fish, crabs, and carnivorous gastropods.
Similar Species
Other small Columbellidae species such as Anachis avara (Greedy Dove Snail), which is typically larger and more strongly ribbed.
Beach Finding Tips
Sift through shell drift or fine shell grit washed up on intertidal beaches during low tide, particularly near seagrass beds.
