Apple Murex
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Phyllonotus, Species: Phyllonotus pomum · Muricidae (Murex or Rock Snail family) · Gastropod (univalve); whole shell with a globose, spiral, and ruggedly spiny shape.
Species
Phyllonotus pomum
Shell Type
Gastropod (univalve); whole shell with a globose, spiral, and ruggedly spiny shape.
Family
Muricidae (Murex or Rock Snail family)
Size
Approximately 2.5 to 3 inches in length. This is an average-sized adult specimen as the species typically ranges from 2 to 4.5 inches.
Color & Pattern
Base color of creamy white to pale tan, featuring prominent dark chocolate brown to reddish-brown spiral banding and streaks. The spines and ridges are highlighted with the same dark pigmentation. The interior aperture (partially visible) typically features a glossy pink, orange, or yellowish-white lining with a dark spot on the upper columella.
Rarity
Common; frequently found by beachcombers in Florida and the Caribbean, though high-quality specimens with intact spines are less common.
Habitat
A marine species found in shallow tropical waters, from the intertidal zone down to about 60 meters. Prefers sandy or muddy bottoms, seagrass beds, and rocky reefs.
Geographic Range
Western Atlantic, ranging from North Carolina down through Florida, the Gulf of Mexico, the Caribbean Sea, and south to Brazil.
Description
The Apple Murex is a rugged and heavy shell characterized by its rounded, 'apple-like' body whorl and rough texture. It features three main varices (vertical ribs) per whorl, adorned with short, blunt, and occasionally sharp spines. The surface is heavily sculpted with fine spiral cords and axial ridges, giving it a cancellated appearance. The spire is moderately high, and the siphonal canal is short and slightly curved.
Key Features
Distinguished by its three prominent varices per whorl, its ruggedly globose shape, and the distinctive dark brown banding. Unlike many other Murex shells, its spines are relatively short and stout. The hallmark for this species is a dark brown blotch usually present on the upper part of the inner lip (columella).
Collector Value
Modest collector value ($5–$15 USD depending on size and quality). While common, it is highly desirable for beginners and generalists due to its classic 'murex' look and beautiful patterns. Gem-quality specimens with perfect spines and deep pink apertures are the most sought after.
Condition Notes
This specimen is in 'Good' to 'Fine' condition. It shows some natural wear and minor erosion on the apex and spine tips. There is a visible patch of bryozoan growth (white lace-like pattern) on the body whorl, indicating it was submerged in a marine environment for some time before being collected. The color remains vibrant and the structural integrity is excellent.
Interesting Facts
The Apple Murex is a carnivorous predator that uses its radula to drill holes into the shells of bivalves like clams and oysters to eat them. Historically, shells related to the Muricidae family were used by ancient civilizations to produce 'Tyrian Purple' dye, though this specific species was more commonly used as a food source in some Caribbean cultures.
Ecological Role
A significant predatory gastropod that helps regulate populations of bivalves and other small mollusks. It is a hardy species but is sensitive to over-collection in localized areas and water pollution.
Similar Species
The Lace Murex (Chicoreus florifer dilectus) is similar but has much longer, more frilly/lacily branched spines and a more elongated shape. The West Indian Murex (Phyllonotus oculatus) is also similar but is generally larger and has different columellar markings.
Beach Finding Tips
Best found after storms or during extreme low tides on Gulf Coast and Florida Key beaches. Look in the swash line or near seagrass wash-ups. They are often camouflaged by sand or algae when alive, so look for the distinctive rugged texture poking through the debris.
