Kingdom: Animalia, Phylum: Mollusca, Class: Gastropoda, Subclass: Caenogastropoda, Order: Neogastropoda, Family: Volutidae, Genus: Cymbiola, Species: Cymbiola nobilis · Volutidae (Volute family) · Gastropod (univalve/marine snail). Whole shell with a heavy, solid, elongated spiral shape.
Species
Cymbiola nobilis
Shell Type
Gastropod (univalve/marine snail). Whole shell with a heavy, solid, elongated spiral shape.
Family
Volutidae (Volute family)
Size
Estimated length of approximately 5 to 6 inches (13-15 cm). Typical adult range for this species is 4 to 8 inches (10-20 cm).
Color & Pattern
Creamy orange to yellowish-tan background color adorned with distinctive dark reddish-brown zig-zag, chevron, and tent-like blotch patterns running in axial bands across the body whorl and spire.
Rarity
Uncommon in beachcombing (as they dwell subtidally), but Common to Fairly Common in commercial shell trade harvested by trawlers.
Habitat
Subtidal benthic marine environment, inhabiting sandy or muddy substrates at depths typically ranging from 5 to 50 meters.
Geographic Range
Indo-West Pacific region, specifically around Singapore, Malaysia, Indonesia, Thailand, and the South China Sea.
Description
A thick, heavy, highly polished gastropod shell featuring a low to moderate conical spire with smooth whorls. The large body whorl dominates the shell, showcasing elegant brown chevron pattern motifs over a warm peach/cream ground color.
Key Features
Smooth, glossy finish; strong columellar folds; distinctive reddish-brown chevron/tent patterning; rounded, robust shoulder lacking prominent spines compared to some related volutes.
Collector Value
Moderately desirable for general collectors and volute specialists. Typical market value ranges from $15 to $40 USD depending on size, pattern contrast, and perfection of the lip and apex.
Condition Notes
Very Good to Fine condition. Smooth finish with strong pigmentation remaining, minimal visible erosion, intact apex, and clean lip margins.
Interesting Facts
Volutes are carnivorous predatory snails that lay egg capsules attached to hard substrates. Unlike many marine snails, volutes lack a free-swimming planktonic larval stage; tiny fully formed snails hatch directly from egg capsules.
Ecological Role
Predatory benthic carnivore feeding primarily on other mollusks and bivalves. Helps control benthic invertebrate populations in soft-bottom marine ecosystems.
Similar Species
Cymbiola vespertilio (Bat Volute), which usually has prominent spiky shoulder knobs; Cymbiola imperialis (Imperial Volute), which features long pointed spines around the whorl shoulder.
Beach Finding Tips
Rarely found intact on public beaches as they live in deeper subtidal waters; best obtained through local fishing ports/trawlers in Southeast Asia or reputable shell dealers.
