Strombus alatus (or Lobatus alatus)
Shell Type
Gastropod, whole shell, spiral shape with flared outer lip

Strombidae (Conch family)
Size
Approximately 3 inches in length, which is average for an adult of this species. Adults typically range from 2.5 to 4.5 inches.
Color & Pattern
Warm golden-brown and tan coloration with subtle darker banding across the body whorl. The spire shows lighter cream and tan tones. Colors appear natural and slightly weathered.
Rarity
Common
Habitat
Shallow subtidal marine environments, typically found on sandy bottoms, seagrass beds, and mudflats in waters ranging from the intertidal zone down to about 60 feet.
Geographic Range
Western Atlantic Ocean, specifically from North Carolina down through Florida, the Gulf of Mexico, and the Caribbean Sea.
Description
A sturdy, compact gastropod featuring a distinctive heavy-shouldered body whorl, a pointed spire, and a flaring outer lip. The shell has a smooth to finely textured exterior with subtle growth lines and a robust structure designed to withstand wave action in shallow waters.
Key Features
Heavy, stout body whorl with a prominent shoulder angle, a distinctively flared outer lip, and a short, pointed spire.
Collector Value
Low to moderate commercial value. Very common in shell shops and popular among beachcombers, though well-preserved specimens with pristine lips are always appreciated.
Condition Notes
Good to Fine condition. The shell is fully intact with no major fractures, though the outer surface shows minor natural weathering and slight fading from exposure.
Interesting Facts
Despite their peaceful herbivorous diet, Fighting Conchs get their name from their active, vigorous defense mechanism. Using a sickle-shaped operculum attached to their foot, they can lunge at aggressors like crabs.
Ecological Role
Acts as an important grazer in seagrass and sandy benthic communities, feeding on detritus and algae. They serve as prey for large crabs, sharks, and sea turtles.
Similar Species
Queen Conch (Aliger gigas), which grows much larger and has a pink interior; and the West Indian Fighting Conch (Strombus pugilis), which has sharper, more pronounced spines on the shoulder.
Beach Finding Tips
Look along shallow sandy beaches and sandbars at low tide, particularly after storms or heavy winds in the Gulf of Mexico and Florida coasts.
