Common Atlantic Dove Shell (also known as Dove Snail)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Columbellidae, Genus: Mitrella, Species: Mitrella lunata · Columbellidae (Dove snail family) · Gastropod (univalve snail), whole shell, spiral shape

Species
Mitrella lunata
Shell Type
Gastropod (univalve snail), whole shell, spiral shape
Family
Columbellidae (Dove snail family)
Size
Approximately 5 to 8 millimeters in length, which is average for this small species. Adults typically range between 5 and 10 millimeters.
Color & Pattern
Glossy surface featuring a warm yellowish-brown or tan base color, accented with characteristic darker zigzag or crescent-shaped markings and a pale or white band encircling the body whorl.
Rarity
Common, frequently found by dedicated beachcombers sorting through shell drift.
Habitat
Shallow subtidal and intertidal zones, often found among algae, seagrass beds, and under rocks on sandy or muddy substrates.
Geographic Range
Western Atlantic Ocean, ranging from Nova Scotia down to Florida, the Gulf of Mexico, and the Caribbean Sea.
Description
A charmingly diminutive, glossy gastropod featuring an elongated-oval outline, a pointed spire, and fine spiral striae near the base. The outer lip is slightly thickened and sometimes denticulate on the interior, perfectly proportioned for its micro-habitat.
Key Features
Tiny size, smooth and glossy texture, distinctive zigzag or spotted pattern often featuring a pale central band, and a narrow aperture with a notched anterior canal.
Collector Value
Low commercial value due to high abundance, but highly prized by micro-shell collectors and enthusiasts who appreciate diversity in miniature marine life.
Condition Notes
Good condition overall, intact spire, with minor natural weathering appropriate for a beach-collected micro-shell. Collectibility grade is Good.
Interesting Facts
Despite their tiny size, dove shells are active predators and scavengers, feeding on small detritus and microalgae using a specialized radula.
Ecological Role
Serves as an important link in the benthic food web, consuming microalgae and organic debris while providing a food source for small fish and predatory invertebrates.
Similar Species
Other members of the Columbellidae family, such as Astyris lunata or Anachis species, which can be distinguished by subtle differences in sculpture, aperture dentition, and color patterns.
Beach Finding Tips
Look in shell-hash lines left by high tides, or collect fine drift sand and examine it using a magnifying glass or stereomicroscope.
