Apple Murex (also known as the Apple Rock Murex)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Chicoreus, Species: Chicoreus pomum · Muricidae (Murex family or rock snails) · Gastropod (univalve), whole shell, spiral shape with a distinct siphonal canal
Species
Chicoreus pomum
Shell Type
Gastropod (univalve), whole shell, spiral shape with a distinct siphonal canal
Family
Muricidae (Murex family or rock snails)
Size
Approximately 2 inches in length, which is on the smaller to average size for this species. Adults typically range from 2 to 4 inches (5 to 10 cm).
Color & Pattern
The shell exhibits a creamy white to pale tan base color, accented by warm brownish-orange highlights and banding, particularly around the shoulder knobs and along the siphonal canal. The colors appear mostly natural with minor sun-bleaching characteristic of beach-worn specimens. The interior aperture is largely concealed in this view, but typically features a pinkish or whitish interior lip.
Rarity
Common, frequently found by beachcombers and divers within its natural geographic range.
Habitat
Inhabits shallow subtidal waters, often found on sand, rubble, or coral reef environments, typically from the intertidal zone down to depths of about 30 meters.
Geographic Range
Western Atlantic Ocean, ranging from North Carolina through Florida, the Gulf of Mexico, the Caribbean Sea, and down to northern South America.
Description
A robust, rounded gastropod shell featuring a distinctively rough, sculpted exterior adorned with prominent axial ribs, tubercles, and spiky fronds along the varices. It possesses a relatively short spire, rounded body whorl, and a moderately long, partially open siphonal canal that curves slightly upward at the tip.
Key Features
Rounded body whorl, prominent sculptural varices with nodular spines, rough textured surface, and a well-developed siphonal canal tinged with orange-brown coloration.
Collector Value
Low to moderate commercial value. While widely appreciated by beginner and intermediate collectors for its attractive structure, it is common enough that specimens usually sell for a few dollars in shell shops.
Condition Notes
Good to Fine condition. The shell is structurally intact with most of its intricate sculptural details preserved, though it shows minor wear on the spines and slight fading typical of a beach or shallow-water find. Grade: Fine.
Interesting Facts
Like many members of the Muricidae family, Chicoreus pomum is a predatory carnivorous snail that feeds on other mollusks and barnacles by drilling holes into their shells or pulling them open, then secreting digestive enzymes.
Ecological Role
Acts as an active marine predator regulating populations of other benthic invertebrates. It occupies a vital middle tier in the coastal marine food web and is preyed upon by larger fish, crustaceans, and cephalopods.
Similar Species
Can be confused with other rock murex species such as the Rose-branch Murex (Chicoreus florifer) or the Lettuce Murex (Chicoreus brevifrons), which tend to have more elaborate, leafy fronds rather than the stubby knobs seen on the Apple Murex.
Beach Finding Tips
Look for specimens along Gulf and Caribbean beaches after heavy storms or rough surf events, particularly near jetties, reefs, or areas with mixed sand and shell rubble.
