Epitonium scalare

Epitonium scalare, common name the precious wentletrap, is a predatory or ectoparasitic species of marine gastropod with an operculum, in the family Epitoniidae, the wentletraps.

In the 17th and 18th century this was once considered to be a very rare shell and specimens changed hands for large sums of money. Johan de la Faille and Cosimo III de' Medici owned a wentletrap.

Its habitat is subtidal in sand.
