Apple Murex (also known as the Common American Murex)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Chicoreus, Species: Chicoreus pomum · Muricidae (Murex family / Rock shells) · Gastropod (univalve), whole shell with a spiral shape and prominent varices.
Species
Chicoreus pomum
Shell Type
Gastropod (univalve), whole shell with a spiral shape and prominent varices.
Family
Muricidae (Murex family / Rock shells)
Size
Approximately 1.5 to 2 inches in length, which is on the smaller side for this species. Adults typically range from 2 to 4 inches.
Color & Pattern
Displays a warm brownish-tan to orange-brown base color, accented with darker brown spiral bands and lighter cream highlights along the ridges and knobs. The colors appear natural with minor weathering.
Rarity
Common, frequently found by beachcombers and divers within its natural geographic range.
Habitat
Found in shallow marine waters, typically from the intertidal zone down to about 30 meters. Prefers sandy, muddy, or rubble bottoms, often near coral reefs or seagrass beds.
Geographic Range
Western Atlantic Ocean, ranging from North Carolina through Florida, the Gulf of Mexico, the Caribbean, and down to northern South America.
Description
A robust, sturdy shell featuring a compact spiral spire, rounded body whorl, and three prominent frilly varices per whorl. The surface is textured with distinct spiral cords and nodes, terminating in a short, partially closed anterior canal.
Key Features
Distinguished by its three prominent varices per whorl, strong spiral ridges, rough textured surface, and a rounded aperture with a finely denticulate outer lip and short siphonal canal.
Collector Value
Low to moderate value. While a staple for amateur shell collectors and commonly found in shell shops, exceptional large or heavily spined specimens command higher interest.
Condition Notes
The shell appears to be in Good condition overall. It is structurally intact with minor wear on the tips and spires due to natural tumbling, retaining much of its original warm coloration.
Interesting Facts
Like other murex snails, Chicoreus pomum is a fierce carnivorous predator that drills into the shells of bivalves or forces them open to feed. Historically, members of the Muricidae family are famous for producing the prized Tyrian purple dye.
Ecological Role
Acts as an important carnivorous predator in benthic marine ecosystems, helping to control populations of bivalves and other gastropods. It is a natural part of the marine food web.
Similar Species
Can be confused with other Atlantic murexes such as the Rose-branching Murex (Bolinus cornutus) or the Apple Murex's close relatives, but easily distinguished by its specific varice count and rounded body shape.
Beach Finding Tips
Best found by beachcombing after heavy storms or tropical weather systems in the Caribbean or Gulf of Mexico, particularly around low tide on shell-rich sandy beaches.
