Ramonella Murex, also known as the Branching Murex or Rose-corn Murex
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Chicoreus, Species: Chicoreus ramosus · Muricidae (Murex family / Rock shells) · Gastropod (univalve snail), whole shell, spiral shape with prominent frondose spines
Species
Chicoreus ramosus
Shell Type
Gastropod (univalve snail), whole shell, spiral shape with prominent frondose spines
Family
Muricidae (Murex family / Rock shells)
Size
Approximately 4-5 inches in length. This is a moderate to large specimen; adults of this species typically range from 4 to 12 inches.
Color & Pattern
Cream to off-white base color adorned with striking dark brown to chestnut-brown axial streaks and spiral banding, extending outward onto the frondose spines. The coloration is completely natural and well-preserved, showing sharp contrast against the pale body whorl.
Rarity
Common to Uncommon, frequently found by divers and occasionally washed ashore in its native range, but well-preserved specimens with intact spines are valued by collectors.
Habitat
Found in marine environments, specifically in shallow subtidal waters, coral reefs, and rocky or rubble substrates, usually ranging from the intertidal zone down to depths of about 30 meters.
Geographic Range
Indo-Pacific region, stretching from the East African coast and the Red Sea across the Indian Ocean to Southeast Asia, Northern Australia, and the western Pacific islands.
Description
A magnificent and heavy marine snail featuring a robust spiral shell adorned with three elaborate, frondose varices per whorl. The surface is textured with rough growth ridges and spiral cords, culminating in distinct, curved, tubular spines that radiate outward. The anterior canal is relatively short, broad, and slightly recurved.
Key Features
Distinguished by three prominent varices per whorl, elaborate open or closed frondose spines along the shoulders, a well-developed parietal tooth, and a whitish to pinkish interior aperture framed by a denticulate outer lip.
Collector Value
Moderately high desirability due to its large size, sculptural complexity, and dramatic spines. Specimens with fully intact, undamaged fronds command higher prices in the collector market, typically ranging from $15 to $50 depending on exact size and condition.
Condition Notes
Fine to Gem condition. The shell is intact with very little wear, retaining almost all of its original frondose spines and vibrant natural color patterns with minimal bleaching.
Interesting Facts
Chicoreus ramosus is the largest species in the genus Chicoreus. Like many muricids, members of this species secrete a yellowish mucus from their hypobranchial gland that turns into a durable purple-blue dye when exposed to sunlight, historically used to produce royal purple dye.
Ecological Role
As active predatory carnivores, Chicoreus ramosus play an important role in controlling populations of other marine invertebrates, primarily feeding on bivalves and other mollusks by boring through their shells or prying them open.
Similar Species
Chicoreus torrefactus (Fire Murex) and Chicoreus brunneus. C. ramosus is generally larger, heavier, and has blunter, sturdier fronds compared to the more delicately fronded C. torrefactus.
Beach Finding Tips
Finding intact specimens washed ashore is rare because the delicate spines easily break in the surf. The best way to acquire pristine specimens is through local dive communities or specialized shell vendors operating within its Indo-Pacific range.
