Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Hexaplex, Species: Hexaplex cichoreum · Muricidae (Murex or Rock Snail family) · Gastropod (univalve); Spiral/Fusiform with heavy varices and spines
Species
Hexaplex cichoreum
Shell Type
Gastropod (univalve); Spiral/Fusiform with heavy varices and spines
Family
Muricidae (Murex or Rock Snail family)
Size
Approximately 4-5 inches in length based on the image perspective. Typical adult size ranges from 2.5 to 6 inches.
Color & Pattern
Base color is typically white to creamy-tan with starkly contrasting dark brown to blackish frond-like spines. The spiral bands often carry this dark pigmentation through the spines, while the body whorl remains lighter. The interior aperture is usually white with a polished porcelain finish.
Rarity
Common; a staple in most beginner and intermediate collections, frequently available through commercial trade but impressive in high-quality form.
Habitat
Found in shallow tropical waters, primarily in intertidal zones and subtidal areas up to 30 meters deep. It prefers sandy or muddy bottoms near coral reefs where prey is abundant.
Geographic Range
Indo-Pacific region, specifically concentrated around the Philippine Islands, Indonesia, and northern Australia.
Description
A robust and visually striking shell characterized by its elaborate ornamentation. It features several varices (rows of spines) per whorl. The spines are typically open or 'foliated,' looking like frilly endive leaves, which gives the species its name. The siphonal canal is moderately long and curved.
Key Features
Distinguished by the contrast between its white body and brownish-black spines, the presence of 6 to 8 varices on the body whorl, and the characteristic leaf-like or frilled structure of the spines.
Collector Value
Low to Moderate ($5 - $25 USD). Its value is determined by the length and 'perfection' of the spines, as they are very fragile and often break in the surf or during transport. Larger, perfectly preserved specimens from specific localities fetch higher prices.
Condition Notes
The specimen in the photograph is in good condition with most spines intact, which is difficult for beach-worn specimens. It shows some minor chipping on spine tips and light encrustation remains, typical for a wild-sourced specimen. Grade: Fine.
Interesting Facts
Like most members of the Muricidae family, this snail is a carnivore that uses its radula and acidic secretions to drill holes through the shells of other mollusks. Historically, related Murex species were the source of 'Tyrian Purple' dye, though the Endive Murex is valued more for its architecture than its pigment.
Ecological Role
Active predator of bivalves and other gastropods. It helps regulate populations of smaller mollusks within the reef ecosystem. It is not currently listed as endangered, though local over-harvesting for the shell trade can occur.
Similar Species
Hexaplex brassica (Cabbage Murex) which has pinker tones and different spine structures, and Hexaplex erythrostomus (Pink-mouthed Murex) which has a distinct pink aperture.
Beach Finding Tips
Best found by diving or snorkeling in shallow reef flats. On beaches, they are most likely found after heavy storms as intact specimens rarely wash up in high-energy surf zones due to their fragile spines.
