See text Epitonium is a genus of small predatory sea snails, marine gastropod mollusks.

[1] The common name wentletraps is derived from the Dutch word wenteltrap, denoting a spiral staircase.

This refers to the striking form and sculpture of the shells of the mollusks in this genus, and to a lesser extent, the whole family.

These snails are predators and feed by inserting their proboscis and biting out small pieces of the anemone's tissues.

These subgenera were based on details of the shell sculpture and not on molecular analysis.
