Kingdom: Animalia; Phylum: Mollusca; Class: Gastropoda; Order: Littorinimorpha; Family: Strombidae; Genus: Aliger; Species: A. gigas · Strombidae (True Conch family) · Gastropod (univalve/spiral). Whole shell with a large, flared outer lip and a high, pointed spire.
Species
Aliger gigas (formerly Strombus gigas)
Shell Type
Gastropod (univalve/spiral). Whole shell with a large, flared outer lip and a high, pointed spire.
Family
Strombidae (True Conch family)
Size
Approximately 8 to 10 inches in length. This is a mature adult specimen, as indicated by the thick, flared lip. Typical adult range is 6 to 12 inches.
Color & Pattern
The exterior is a creamy, sandy-beige color with hints of light brown and natural weathering. The most striking feature is the glossy, porcelain-like interior of the aperture, which fades from a deep rosy pink to a soft pastel peach and creamy white near the margins.
Rarity
Common. While once incredibly abundant, they are now protected in many regions due to overfishing; however, they remain the most iconic and frequently seen large shell in the Caribbean.
Habitat
Found in shallow, warm marine waters, typically in seagrass beds (especially Thalassia testudinum) and occasionally on sandy substrates or coral rubble. Found at depths ranging from 1 to 30 meters.
Geographic Range
Tropical Western Atlantic, including the Caribbean Sea, Florida Keys, Bermuda, and the Bahamas.
Description
A massive, heavy-bodied shell characterized by a high spire with blunt spikes on each whorl. The adult specimen features a magnificent, wide-flaring outer lip that provides stabilty on the ocean floor. The exterior is rough and calcified, often serving as a host for algae in the wild, contrasting beautifully with the smooth, lustrous pink interior.
Key Features
Large, flared outer lip; deep pink aperture coloration; prominent blunt spines on the shoulder of the whorls; heavy, thick shell wall; and a 'stromboid notch' near the anterior end of the lip.
Collector Value
Moderate. Common specimens sell for $20–$50 USD. High-value specimens are exceptionally large (over 12 inches), have a 'Gem' quality lip, or possess unusual deep magenta coloration. It is a staple of any tropical shell collection.
Condition Notes
Good to Fine. The pink color is well-preserved, suggesting it has not been left in direct sunlight for an extended period. The lip shows minor chipping at the top edge, typical of natural wear or handling, but the spire is intact. It is a highly collectible decorator-grade specimen.
Interesting Facts
The animal within has complex eyes on long stalks and moves using a 'jumping' motion with its sickle-shaped operculum. Historically, these shells were used to make cameos, tools, and trumpets. They sometimes produce rare, non-nacreous 'Conch Pearls'.
Ecological Role
Important herbivore that grazes on algae and seagrass detritus. They are prey for sea stars, octopuses, and nurse sharks. Currently listed under CITES Appendix II, meaning international trade is strictly regulated to prevent endangerment.
Similar Species
Milk Conch (Strombus costatus) which is smaller and lacks the pink aperture; King Conch (Strombus goliath) which is much larger with a more massive lip; and Fighting Conchs, which are significantly smaller.
Beach Finding Tips
Look for them in the Caribbean or Florida Keys. Intact adults are rarely found directly on the beach unless washed up by a major storm; they are more commonly found by snorkeling in seagrass beds just offshore.
