Apple Murex (also known as the Pink-mouthed Murex or Branching Murex)
Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Muricidae, Genus: Hexaplex, Species: Hexaplex pomum · Muricidae (Murex or Rock Snail family) · Gastropod, whole shell, spiral shape with prominent spines and varices
Species
Hexaplex pomum
Shell Type
Gastropod, whole shell, spiral shape with prominent spines and varices
Family
Muricidae (Murex or Rock Snail family)
Size
Approximately 3.5 to 4 inches in length. This is an average to large size for the species, which typically ranges from 2 to 5 inches.
Color & Pattern
The exterior is heavily weathered and sun-bleached, presenting a uniform chalky off-white to pale cream color. Faint traces of original brownish or tan banding may be obscured by the bleaching. The interior of the aperture shows subtle hints of pinkish or peach tones characteristic of the species.
Rarity
Common. Often found washed up on beaches in the Caribbean and Florida after storms, though well-preserved specimens with intact spines are more prized.
Habitat
Found in shallow marine waters, typically ranging from the intertidal zone down to depths of about 50 meters (160 feet). They inhabit hard substrates, coral rubble, rocky areas, and seagrass beds.
Geographic Range
Western Atlantic Ocean, spanning from North Carolina through Florida, the Gulf of Mexico, the Caribbean Sea, and down to northern South America.
Description
A robust, heavy, and rugose murex shell characterized by rounded whorls adorned with prominent, leafy varices and sharp spines. The body whorl is large and bulbous, terminating in a moderately long, partially closed anterior canal. The outer lip is thickened and toothed on the inner margin, framing an oval aperture.
Key Features
Bulbous body whorl, prominent rows of spine-bearing varices, a distinct anterior canal, and a toothed outer lip surrounding an aperture that often features a pinkish interior hue.
Collector Value
Low to moderate commercial value due to its common occurrence. While prized by beginner collectors for its sculptural form and spines, heavily bleached beach-grade specimens generally hold nominal value.
Condition Notes
Fair to Good condition. The shell is structurally intact with most major spines present, but it suffers from significant sun-bleaching and weathering which has removed the natural surface coloration and finer sculptural details.
Interesting Facts
Murex snails are predatory carnivores that feed on bivalves and other gastropods by boring holes in their shells or prying them open using their strong muscular foot. Historically, certain members of the Muricidae family were used to produce royal purple dye.
Ecological Role
Acts as an active marine predator helping to control populations of barnacles, clams, and other mollusks. It serves as part of the benthic food web, being preyed upon by larger fish and crustaceans.
Similar Species
Chicoreus ramosus (Branched Murex) and Hexaplex radix. Hexaplex pomum is distinguished by its rounder, apple-like body and specific variceal architecture compared to other Atlantic muricids.
Beach Finding Tips
Look along high-tide lines and drift lines on Gulf and Caribbean beaches, especially following strong onshore winds or tropical storms that churn up shallow offshore rocky or rubble bottoms.
