Phylum: Mollusca, Class: Gastropoda, Order: Littorinimorpha, Family: Strombidae, Genus: Strombus, Species: Strombus alatus · Strombidae (True Conchs) · Gastropod (univalve); Spiral/Conical shape with a heavy flared outer lip.
Species
Strombus alatus
Shell Type
Gastropod (univalve); Spiral/Conical shape with a heavy flared outer lip.
Family
Strombidae (True Conchs)
Size
Approximately 3.5 to 4 inches in length based on the hand comparison. This is a mature adult specimen as evidenced by the developed lip. Adults typically range from 2.5 to 4.5 inches.
Color & Pattern
Rich shades of cinnamon brown, tan, and cream. The exterior shows characteristic darker brown axial zigzag patterns and bands. The interior aperture is a glossy, deep orange to brownish-purple tone, which appears naturally preserved and not sun-bleached.
Rarity
Common. It is one of the most frequently found conch species on Gulf Coast beaches, though finding one in this high-quality, unbroken condition is a great find.
Habitat
Found in shallow marine waters, typically in intertidal and subtidal zones. Prefers sandy or muddy bottoms and seagrass beds where it can graze on algae.
Geographic Range
Western Atlantic: found from North Carolina south to Florida, and throughout the Gulf of Mexico.
Description
This is a robust, heavy shell with a high spire and prominent, sharp knobs or spines on the shoulder of the body whorl. The outer lip is thick and flared, featuring the diagnostic 'stromboid notch' near the anterior end. Its surface has a slightly matte texture on the exterior with a highly polished, vitreous interior.
Key Features
The most distinguishing marks are the strong spines on the shoulder, the flared outer lip, and the specific 'stromboid notch' (a small indentation on the lip) which the living animal uses to peek its eyes out through a long stalk.
Collector Value
Modest but desirable for regional collections. While not worth a high monetary value (typically $5-$15 USD), its excellent condition and deep coloration make it a 'display-grade' specimen for hobbyists.
Condition Notes
Excellent condition (Fine to Gem grade). The spire is intact, the color is vibrant, and the outer lip shows very little chipping or wave-wear. There are no visible predatory bore holes or significant encrustations, suggesting it was found shortly after the animal deceased or as a 'dead-fall' in a protected area.
Interesting Facts
Despite the name, they are not aggressive; the move in a 'leaping' fashion by digging their claw-like operculum into the sand and thrusting themselves forward. They have highly developed eyes on the end of long, flexible stalks that are surprisingly anthropomorphic.
Ecological Role
Herbivorous grazer that helps control algae growth in seagrass ecosystems. They are prey for larger mollusks like Horse Conchs, as well as rays and sea turtles.
Similar Species
Strombus pugilis (West Indian Fighting Conch) which is generally more orange/red and has larger, more pronounced spines on the penultimate whorl.
Beach Finding Tips
Best found after storms or high tides on Gulf Coast beaches (like Sanibel Island). Look in the 'trough' just off the shoreline or during extreme low tides near seagrass flats.
