Apple Murex (also known as the Common Atlantic Murex)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Phyllonotus, Species: Phyllonotus pomum · Muricidae (Murex family or Rock snails) · Gastropod (univalve snail), whole shell, spiral shape with prominent sculptural nodes and spines
Species
Phyllonotus pomum
Shell Type
Gastropod (univalve snail), whole shell, spiral shape with prominent sculptural nodes and spines
Family
Muricidae (Murex family or Rock snails)
Size
Approximately 2 to 3 inches in length, which is slightly below average. Adult Apple Murex shells typically range from 2.5 to 5 inches.
Color & Pattern
Cream to light tan or grayish-white base color, accented with reddish-brown to dark brown blotches, streaks, and spiral bands on the nodes and ridges. The colors appear mostly natural with some slight weathering.
Rarity
Commonly found in its natural range, though intact specimens with good color and intact spines require some searching on beaches after storms.
Habitat
Shallow subtidal zones, intertidal areas, and offshore waters down to about 150 feet. Typically found on sandy, muddy, or rubble bottoms, and near coral reefs or seagrass beds.
Geographic Range
Western Atlantic Ocean, ranging from North Carolina and Florida through the Gulf of Mexico, the Caribbean Sea, and down to northern South America (Brazil).
Description
A sturdy, heavy shell featuring a robust rounded body whorl, a moderately elevated spire, and three to four varices per whorl adorned with blunt knobs and short, frilly spines. The surface is textured with rough spiral cords and fine growth lines. The aperture is ovate with a finely denticulated outer lip and a distinct, open siphonal canal.
Key Features
Heavy, rugged construction; prominent rounded knobs on the shoulder; three to four varices per whorl; ovate aperture with a toothed outer lip; and a relatively short, thick siphonal canal.
Collector Value
Moderately valued by shell collectors, particularly for educational displays or beginner-to-intermediate collections. Common specimens generally have a low monetary value (a few dollars), but large, gem-grade specimens with exceptionally long, undamaged spines can fetch higher prices.
Condition Notes
Good to Fine condition. The shell is structurally intact with the main body and spire well-preserved. Some of the delicate peripheral spines show minor wear or rounding from wave action, typical of beach-collected specimens, but the overall form and coloration remain highly attractive.
Interesting Facts
Apple Murex snails are voracious carnivorous predators that feed on other mollusks, barnacles, and bivalves. They bore holes into the shells of their prey using their radula combined with an accessory boring organ that secretes softening chemicals.
Ecological Role
Acts as an important carnivorous predator in marine benthic ecosystems, helping to regulate populations of bivalves and other marine invertebrates. Empty shells also provide essential mobile homes for hermit crabs.
Similar Species
Can be confused with the West Indian Murex (Phyllonotus pomatus) or the Apple Murex variants, but can be distinguished by its distinct nodal patterns and shorter, sturdier siphonal canal compared to more elaborate murex species like the Venus Comb.
Beach Finding Tips
Best found by beachcombing along Gulf of Mexico and Florida coastlines following strong onshore winds, tropical storms, or rough sea conditions that churn up shallow subtidal areas.
