Apple Murex (also known as the Branch Murex or Apple Rock-Shell)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Phyllonotus, Species: Phyllonotus pomum · Muricidae (Murex family / Rock shells) · Gastropod (univalve), whole shell, spiral shape with ornate varices and spines
Species
Phyllonotus pomum
Shell Type
Gastropod (univalve), whole shell, spiral shape with ornate varices and spines
Family
Muricidae (Murex family / Rock shells)
Size
Approximately 2.5 to 3 inches in length, which is slightly below average. Adult specimens typically range from 2 to 5 inches.
Color & Pattern
Pale creamy white to light tan base coloration with faint brownish spiral bands. The interior aperture exhibits a soft pinkish or peach blush. Colors appear somewhat weathered and sun-bleached from exposure.
Rarity
Common
Habitat
Found in shallow marine waters, typically ranging from the intertidal zone down to depths of about 30 meters. Prefers hard substrates, rocky bottoms, coral rubble, and occasionally sandy areas near reefs.
Geographic Range
Western Atlantic Ocean, spanning from North Carolina through Florida, the Gulf of Mexico, the Caribbean Sea, and down to northern South America.
Description
A sturdy, rough-textured marine snail shell featuring a rounded body whorl adorned with prominent, frilly varices and sharp, pointed spines. The short, sturdy siphonal canal is partially open, and the outer lip is thickened and denticulated on the inner margin. The overall architecture is rugged and defensively armored.
Key Features
Prominent frilly varices, sharp recurved spines along the shoulders, a rounded globular body whorl, a well-defined short siphonal canal, and a pinkish-tinged aperture interior.
Collector Value
Moderately common and widely collected by beachcombers and shell enthusiasts. Specimen value is generally low to moderate ($2 to $10) unless exceptionally large, brightly colored, or possessing pristine, unbroken frills.
Condition Notes
Good condition. The shell is intact with minor tip wear and some sun-bleaching. Spines are mostly preserved though slightly blunted. Graded as Good to Fine collectibility.
Interesting Facts
Like many murex snails, Phyllonotus pomum is a carnivorous predator that feeds on bivalves and other gastropods, using its radula and acidic secretions to bore into or force open prey shells. Members of the Muricidae family were historically used by ancient civilizations to produce valuable purple dye.
Ecological Role
Acts as an important carnivorous predator in marine benthic ecosystems, helping control herbivorous and filter-feeding populations. Empty shells frequently serve as mobile homes for hermit crabs.
Similar Species
Pink-lipped Murex (Phyllonotus margaritensis) which is generally larger and more elongated, and the Chicoreus genus which typically features even more elaborate, leafy fronds.
Beach Finding Tips
Best found by beachcombing after stormy weather or heavy wave action in the Caribbean, Florida keys, or Gulf coast regions, particularly around rocky jetties, shell heaps, and shallow subtidal grass flats.
