Odostomia exarata
species of mollusc
Odostomia exarata is a species of sea snail, a marine gastropod mollusc in the family Pyramidellidae, the pyrams and their allies.
Description
The elongate-ovate shell is white. Its length is 6.3 mm. The whorls of the protoconch are obliquely immersed, with only the tilted edge of the last volution visible. The five whorls of the teleoconch are marked by two spiral keels which divide the space between the sutures into three equal parts. The posterior of these keels shows weak crenulation. The periphery of the body whorl is marked by a third keel which is almost as strong as those on the spire. A fourth keel, which is considerably less strong, occupies the middle of the base. The rounded spaces between the keels are marked by feeble lines of growth. The aperture is irregularly oval.
This brief starts where responsible research should: with the source description of “Odostomia exarata” as species of mollusc. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of mollusc. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q7078122. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
