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. [1]
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.
This species is distributed in the Red Sea, in the Indian Ocean along Madagascar and South Africa, in the South West Pacific Ocean and along Fiji Islands and Japan.
Adult shells of this species attain a length of between 25 mm to 72 mm. [2]
Many Epitonium species have shells that are very attractive and quite interesting in their structure. However this species is particularly striking, partly because it is very large compared with the great majority of other species within the genus, but also because the whorls themselves do not touch and so the shell is held together only by the well-developed ribs or costae.
The shell of Epitonium scalare has sculpture consisting of raised ribs that are known as costae. Costae are a very common feature in shells of many Epitonium species.
Wentletraps are small, often white, very high-spired, predatory or ectoparasitic sea snails, marine gastropod mollusks in the family Epitoniidae.
The gastropod shell is part of the body of a gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group.
