Phylum: Mollusca, Class: Gastropoda, Order: Littorinimorpha, Family: Epitoniidae, Genus: Epitonium, Species: Epitonium scalare · Epitoniidae (Wentletrap family) · Gastropod (spiral, turreted shape), whole shell
Species
Epitonium scalare
Shell Type
Gastropod (spiral, turreted shape), whole shell
Family
Epitoniidae (Wentletrap family)
Size
Approximately 2 to 3 inches in length, which is on the larger side for wentletraps as many species typically range between 0.5 to 2 inches.
Color & Pattern
Milky white to creamy beige with subtle brownish-tan bands winding between the prominent raised ribs. The colors appear natural and slightly weathered with a matte finish.
Rarity
Uncommon to Rare depending on the specific species, with historically prized large specimens considered highly desirable collector items.
Habitat
Found in marine environments, typically inhabiting shallow to moderately deep subtidal waters, often associated with sea anemones upon which they feed, living on sandy or rubble substrates.
Geographic Range
Indo-West Pacific region, ranging from East Africa across the Indian Ocean to Southeast Asia, Japan, and northern Australia.
Description
An elegant, highly distinctive turreted shell characterized by its tall, tapering spire composed of loosely connected or detached whorls separated by deep sutures, adorned with prominent, blade-like transverse axial ribs (costae) that give it a unique staircase-like appearance.
Key Features
High-spired turreted shape, deep sutures between whorls, and prominent, continuous blade-like axial ribs running vertically down the length of the spire.
Collector Value
Moderately high collector value. While common wentletraps are affordable, large and perfectly preserved specimens of certain species command high prices among serious conchologists.
Condition Notes
Good condition with minor wear on the apex and aperture lip, retaining most of its natural coloration and sculptural integrity. Collectibility grade: Good to Fine.
Interesting Facts
Historically, wentletraps were so prized by European collectors in the 18th century that fake specimens were meticulously crafted from rice paste and sold to unsuspecting buyers for small fortunes.
Ecological Role
Carnivorous predators that specialize in feeding on sea anemones and corals using a specialized proboscis, playing a niche role in regulating cnidarian populations.
Similar Species
Other members of the Epitoniidae family, such as Epitonium lamellosum or Cirsotrema species, which can be distinguished by differences in rib spacing, whorl attachment, and overall proportions.
Beach Finding Tips
Finding wentletraps on beaches requires careful searching among shell drift lines after storms, or diving in subtidal areas near sea anemones.
