Reticulated Murex or Ramose Murex (also known as Chicoreus ramosus)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Chicoreus, Species: Chicoreus ramosus · Muricidae (Murex family) · Gastropod (snail/univalve), whole shell, spiral shape with prominent frilly spines
Species
Chicoreus ramosus
Shell Type
Gastropod (snail/univalve), whole shell, spiral shape with prominent frilly spines
Family
Muricidae (Murex family)
Size
Approximately 4-5 inches in visible length, which is moderate to large for the species. Adults typically range from 3 to 12 inches, with 6 inches being very common for fully mature specimens.
Color & Pattern
Cream to whitish base color heavily overlaid with rich chestnut brown, dark brown, and reddish-brown spiral bands, flames, and streaks. The spines and varices feature intricate branching patterns in darker browns. Colors appear natural, vibrant, and well-preserved with no extreme sun-bleaching.
Rarity
Common to Uncommon depending on the specific locality; widely distributed across the Indo-Pacific but prized for its elaborate fronds and complex sculptural form.
Habitat
Found in shallow sub-tidal waters, typically on coral rubble, rocky bottoms, and sand flats from the low intertidal zone down to depths of about 40 meters (130 feet). Marine species.
Geographic Range
Indo-Pacific region, spanning from East Africa and the Red Sea across the Indian Ocean to Southeast Asia, northern Australia, and extending into the western Pacific as far as southern Japan and Polynesia.
Description
A magnificent and heavily ornamented marine gastropod featuring three robust varices per whorl. Each varix is adorned with numerous branching, frilly, palm-like spines that give the shell a strikingly dramatic, architectural silhouette. The surface is textured with rough spiral cords and nodes, leading to a moderately long, slightly curved siphonal canal. The aperture is oval with a pinkish-white interior and a finely denticulate outer lip.
Key Features
Three distinct varices per whorl, highly elaborate and branching frond-like spines, rough spiral sculpture, and a prominent, slightly recurved siphonal canal.
Collector Value
Moderately high desirability due to its striking appearance and large, dramatic fronds. Specimens with intact, undamaged spines command higher prices. Generally valued between $15 to $50 depending on exact size and perfection of the spines.
Condition Notes
Good to Fine condition. The shell appears mostly intact with natural coloration, though minor tip wear on some of the delicate spines is typical for specimens of this size, typical collectibility grade is Fine.
Interesting Facts
Chicoreus ramosus is the largest species in the genus Chicoreus. Historically, members of the Muricidae family were used to produce the famous and highly valuable Tyrian purple dye utilized by ancient Mediterranean civilizations.
Ecological Role
As a carnivorous predator, Chicoreus ramosus plays a vital role in controlling populations of other benthic molluscs and barnacles by boring into their shells or prying them open. They are part of the marine food web, preyed upon by large fish and crustaceans.
Similar Species
Chicoreus palmarosae (Rose-branch Murex) and Chicoreus torrefactus (Scorched Murex). Chicoreus ramosus can be distinguished by its larger overall size, heavier shell structure, and generally whitish-brown coloration compared to the rosy tints or darker scorches of its relatives.
Beach Finding Tips
Finding live or pristine specimens requires diving or snorkeling in shallow tropical reefs and rocky areas during calm sea conditions. Beach-worn fragments are more common on Indo-Pacific beaches.
