 word for a spiral staircase, a reference to the striking form and sculpture of the shells of the mollusks in this genus, and to a lesser extent, the whole family.

The genus Epitonium has been divided in the past by some authors into several subgenera, but these subgenera were based only on shell characters and did not reflect the true underlying relationships or phylogeny.

Shell description

Epitonium shells are high-spire

Life habits

These snails are predators and feed by inserting their proboscis

A proboscis is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In simpler terms, a proboscis is the straw-like mouth found in several varieties of species.-Etymology:...

Species

Species within the genus Epitonium include:

Note: Some malacologists have recently placed many of the more than 600 named species into other genera, which were previously considered to be subgenera of the genus Epitonium. On the other hand, many species that belonged to subgenera of Epitonium are now included in Epitonium. These subgenera were based on details of the shell sculpture and not on molecular analysis.
