Apple Murex (also known as the Apple Rock Murex)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Phyllonotus, Species: Phyllonotus pomum · Muricidae (Murex family) · Gastropod, whole shell, spiral shape
Species
Phyllonotus pomum
Shell Type
Gastropod, whole shell, spiral shape
Family
Muricidae (Murex family)
Size
Approximately 3 inches in length, which is a very typical and average size for adult specimens. Full-grown adults generally range from 2.5 to 5 inches.
Color & Pattern
The shell features an off-white or cream base color overlaid with rich brownish-orange to chestnut spiral bands and streaks. The texture appears natural with some weathering. The interior of the aperture is a smooth, glossy light peach to pinkish-white.
Rarity
Common
Habitat
Found primarily in shallow subtidal waters down to moderate depths, typically inhabiting sandy, muddy, or rubble-strewn bottoms, as well as seagrass beds and areas near coral reefs. It is a marine species.
Geographic Range
Western Atlantic Ocean, ranging from North Carolina down through Florida, the Gulf of Mexico, the Caribbean Sea, and south to northern South America (Brazil).
Description
A sturdy, rough-textured marine snail shell characterized by strong spiral ridges, rounded body whorls, and prominent varices adorned with blunt knobs or short spines. It features a well-developed, rounded aperture with a toothed outer lip and a short, partially closed canal.
Key Features
Rounded, bulbous body whorl with rough sculptural varices, distinctive brownish spiral banding over a cream base, a prominent toothed outer lip, and a short anterior canal.
Collector Value
Moderately common and affordable, making it a popular staple for beginner and intermediate shell collectors. Specimens with exceptional size, vibrant color banding, or pristine spiny varices command higher prices, though typical shells are widely available in tourist and specialty shell shops.
Condition Notes
Good condition with minor natural weathering and slight fading of exterior colors, but structurally intact with a well-preserved overall form and clearly defined sculpture.
Interesting Facts
Like many members of the Muricidae family, the Apple Murex is a predatory carnivorous snail that feeds on bivalves by drilling holes in their shells or forcing them open. Historically, murex snails are famous for producing a valuable purple dye used by ancient civilizations.
Ecological Role
Acts as an active carnivorous predator helping to regulate bivalve populations in marine benthic ecosystems. Empty shells also provide vital mobile homes for hermit crabs and substrate for various encrusting organisms.
Similar Species
Can be confused with the West Indian Murex (Phyllonotus brevifrons), which typically has more elaborate, longer fronds and a darker coloration, or the Pink Murex (Phyllonotus pomum variants), distinguishable by minor differences in spine length and aperture tint.
Beach Finding Tips
Best found by beachcombing along Gulf and Caribbean coastlines after strong onshore winds or storms, or by wading in shallow, calm waters during low tide near seagrass beds and rocky reef fringes.
