Species
Strombus alatus
Shell Type
Gastropod (Spiral, conical with broad shoulders)
Family
Strombidae (True Conchs)
Size
Approximately 3.5 to 4 inches in length. This is an average adult size; the species typically ranges from 2.5 to 4.5 inches.
Color & Pattern
Base color of creamy tan to brownish-orange with subtle lighter bands. The shell shows longitudinal streaks and a warm, polished-pink to dark-brown interior aperture. The exterior appears slightly weathered with some natural encrustation near the shoulder.
Rarity
Very Common
Habitat
Shallow marine waters, specifically sandy or muddy bottoms and seagrass beds. Found from the intertidal zone to depths of about 150 feet.
Geographic Range
Western Atlantic, specifically from North Carolina south to Florida and the Gulf of Mexico.
Description
A robust, heavy-set gastropod shell featuring a high spire and prominent, pointed knobs on the shoulders of the body whorl. The shell tapers towards the anterior canal and possesses the characteristic 'stromboid notch' on the outer lip. This specimen shows a thick, flared lip indicative of a mature adult.
Key Features
Sharp spines or knobs on the shoulder; a glossy, thickened outer lip; the stromboid notch (a small indentation near the bottom of the outer lip); and a solid, heavy build.
Collector Value
Minimal financial value ($2-$10) due to its abundance, but highly desirable for beginners and regional collectors for its classic shape and beautiful aperture colors.
Condition Notes
Good condition. The shell is structurally intact with a complete spire and lip. There is a patch of calcified tubeworm or bryozoan growth on the back, and the color is slightly dulled from exposure, suggesting it was found as a beach specimen rather than taken alive.
Interesting Facts
The 'fighting' name comes from the animal's aggressive behavior when handled or when encountering predators; it uses its sharp, operculum-tipped foot to kick and flip itself away. Unlike most snails that crawl, conchs move in a series of hops.
Ecological Role
An important herbivore that grazes on algae and detritus in seagrass ecosystems. They serve as a food source for larger predators like octopuses and sea stars.
Similar Species
Strombus pugilis (West Indian Fighting Conch), which is generally more orange/red, has larger spines, and a more deeply colored aperture.
Beach Finding Tips
Best found on Gulf Coast beaches after winter storms or at very low tides. Look for them partially buried in the sand near the water line or in tide pools.
