Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Chicoreus, Species: Chicoreus spectrum · Muricidae (Murex family or Rock Snails) · Gastropod (univalve snail), whole shell with spiral shape and elaborate frilly fronds/spines
Species
Chicoreus spectrum
Shell Type
Gastropod (univalve snail), whole shell with spiral shape and elaborate frilly fronds/spines
Family
Muricidae (Murex family or Rock Snails)
Size
Approximately 3 to 4 inches in length, which is a standard adult size for this species. Adults typically range from 2.5 to 5 inches.
Color & Pattern
Rich golden-brown to tan base color with darker brown spiral banding and striking pinkish-lavender tips on the elaborate, frilled fronds and spines. The colors are entirely natural and vivid. The aperture interior is white to pale cream, leading to a closed or partially visible canal.
Rarity
Uncommon to Rare; highly sought after by collectors due to the delicate and intricate frills which are frequently broken or damaged.
Habitat
Shallow to moderately deep subtidal waters, typically found living on coral rubble, rocky bottoms, and coralline algae environments in tropical marine waters.
Geographic Range
Indo-Pacific region, including the Philippines, Indonesia, and surrounding tropical waters.
Description
An exquisite and highly ornate gastropod showcasing elaborate, leaf-like frills and branching fronds with characteristic pinkish tips along its varices. The shell features a sturdy spiral body whorl, a moderately high spire, and a distinct siphonal canal. The surface texture is rugged yet delicately adorned with intricate, lace-like frills that give it a regal, architectural appearance.
Key Features
Distinguished by its three prominent varices per whorl, extensive and deeply frilled, branching fronds tipped with delicate pink or lavender, and a well-developed siphonal canal.
Collector Value
High collector value. Because the intricate fronds are easily broken, specimens with intact, undamaged frills like this one command a premium among serious conchologists and shell collectors. Typically valued from $30 to over $100 depending on exact size and perfection.
Condition Notes
The specimen appears to be in Fine to Gem condition, with most of its delicate, highly fragile frilled fronds intact—a rarity for this species, as these delicate structures are easily damaged or broken during collection and transport.
Interesting Facts
Murex snails are predatory carnivores that feed on other mollusks and barnacles by boring holes into their shells or prying them open. Historically, some members of the Muricidae family were used to produce the famous and costly Tyrian purple dye prized by ancient civilizations.
Ecological Role
As active carnivorous predators, Chicoreus species help regulate populations of other marine invertebrates, maintaining balance within coral reef and rocky bottom ecosystems.
Similar Species
Chicoreus ramosus (Branched Murex) which is generally larger and heavier, and Chicoreus palmarosae (Rose-branched Murex) which features even more pronounced, intensely pink, fern-like fronds.
Beach Finding Tips
Because these inhabit subtidal and deeper waters, they are rarely found pristine on sandy beaches. Finding them usually requires diving, obtaining specimens from local fishermen, or sourcing them via reputable specialty shell dealers.
