Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Murex, Species: Murex tribulus · Muricidae (Murex family) · Gastropod, whole spiral shell
Species
Murex tribulus
Shell Type
Gastropod, whole spiral shell
Family
Muricidae (Murex family)
Size
Approximately 4 to 5 inches in length including the long siphonal canal. Typical species range is 3 to 6 inches.
Color & Pattern
Uniform creamy white to pale tan. The color appears natural and untampered, though lacking the subtle brownish bands sometimes found in fresh specimens.
Rarity
Common, though pristine specimens with all delicate spines intact are prized.
Habitat
Shallow subtidal waters, typically found on sandy or muddy bottoms, often in bays and coral reef fringes down to depths of about 30 meters.
Geographic Range
Indo-West Pacific region, including the Red Sea, East Africa, Indian Ocean, and across to Southeast Asia and Australia.
Description
An exceptionally delicate and striking shell featuring a long, straight siphonal canal lined with numerous needle-like, comb-like spines. The body whorl is rounded with spiral ridges, and the overall form is architectural and fragile.
Key Features
Extremely long siphonal canal bordered by two rows of long, straight, needle-sharp spines resembling a comb.
Collector Value
Highly desirable for its aesthetic appeal and intricate structure. Specimens with completely intact spines command higher prices, typically ranging from $15 to $50 depending on size and perfection.
Condition Notes
Gem to Fine condition. The delicate spines are remarkably intact with minimal breakage, which is rare for this fragile species.
Interesting Facts
The Venus Comb Murex uses its long spines to prevent sinking into soft mud and to deter predators. Like many muricids, it is a predatory snail that drills into other mollusks to feed.
Ecological Role
Acts as a carnivorous predator controlling bivalve populations in its benthic habitat, serving as both predator and prey in the marine food web.
Similar Species
Murex ternispina and Murex clamator, which have slightly different spine arrangements or shorter canals.
Beach Finding Tips
Because of the extreme fragility of the spines, live specimens or pristine shells are rarely found intact on open beaches; they are usually retrieved by divers or local fishermen in deeper water.
