Species
Aliger gigas (formerly Strombus gigas)
Shell Type
Gastropod (univalve snail). Whole shell featuring a large, heavy body whorl with a wide flaring outer lip.
Family
Strombidae (True Conch family)
Size
Estimated length 8 to 11 inches (20-28 cm). Typical adult range is 6 to 12 inches (15-30 cm) long, weighing up to 5 lbs.
Color & Pattern
Exterior is a rough, yellowish-tan to cream color with subtle brownish mottling. The interior aperture and flaring lip showcase a glossy, vibrant, gradient transition from soft porcelain white to deep rosy pink and orange-pink tones.
Rarity
Common to find as commercial/souvenir specimens; Uncommon to find intact on beaches due to heavy harvesting, legal protections, and wave breakage. Protected under CITES Appendix II.
Habitat
Shallow tropical marine waters, usually 2 to 15 meters deep in sandy bottoms, seagrass beds (especially Thalassia testudinum), and near coral reefs.
Geographic Range
Warm waters of the Tropical Western Atlantic, including the Caribbean Sea, Florida Keys, Bahamas, Gulf of Mexico, and northern coast of South America.
Description
A classic adult Queen Conch specimen displaying a massive, broadly expanded flaring outer lip with wavy margins. The spire features blunt, heavy conical spines along the shoulders of the whorls. The smooth interior is brilliantly polished naturally in vivid pink and ivory hues, contrasting dramatically with the rugged exterior sculpture.
Key Features
Extensive flaring outer lip (indicates adult maturity), bright glossy pink aperture interior, short pointed spire surrounded by strong shoulder knobs/spines, and a distinct stromboid notch near the anterior canal.
Collector Value
Moderately desirable for collectors and home decor. Large adult specimens with vibrant pink interior lips in good condition typically fetch $30 - $75 USD. International trade is regulated strictly by CITES.
Condition Notes
Very Fine display condition. The interior lip exhibits strong pink coloration and a high natural sheen without significant fading. Minimal erosion on the exterior spire and pristine lip edges with only slight natural wear.
Interesting Facts
Queen Conchs do not grow in length after reaching maturity; instead, they focus energy on thickening their massive outer lip. They can live up to 40 years and occasionally produce rare, highly valuable pink conch pearls.
Ecological Role
Herbivorous grazers that feed primarily on macroalgae and detritus attached to seagrass leaves, helping maintain clear water and healthy seagrass ecosystems. Overfished widely, leading to strict international conservation laws.
Similar Species
Milk Conch (Lobatus costatus) which has a white or cream aperture, Hawkwing Conch (Lobatus raninus) which is much smaller with a dark aperture, and King Helmet (Cassis madagascariensis) which has a shield-like flat parietal area.
Beach Finding Tips
Look in shallow sand flats and seagrass meadows at low tide in allowed regions. Beachcombers often find broken fragments or eroded shells after severe storms; complete specimens usually require diving or snorkeling.
