Odostomia mendozae

Definition
Odostomia mendozae is a species of small marine gastropod mollusk in the family Pyramidellidae, commonly known as the pyrams and their allies.

Overview

• Taxonomic classification

  • Kingdom: Animalia
  • Phylum: Mollusca
  • Class: Gastropoda
  • Order: Heterobranchia
  • Superfamily: Pyramidelloidea
  • Family: Pyramidellidae
  • Genus: Odostomia
  • Species: O. mendozae

• Discovery and nomenclature
  The species was formally described in the early 20th century by malacologists (exact author and year should be verified from primary taxonomic literature).

• Distribution
  Records indicate that O. mendozae occurs in marine waters of the northeastern Pacific Ocean, with specimens collected from coastal regions of western North America. Precise range limits are not fully documented in readily accessible sources.

Etymology/Origin

• The generic name Odostomia derives from the Greek words odous (“tooth”) and stoma (“mouth”), referring to the characteristic tooth‑like columellar fold found in many species of the genus.
• The specific epithet mendozae is a Latinized form likely honoring a person bearing the surname Mendoza or referencing a geographic location named Mendoza; the original description would contain the exact rationale.

Characteristics

• Shell morphology: As with other Odostomia species, the shell is minute (generally 2–5 mm in length), elongate‑conical, and smooth or faintly sculptured. The aperture is ovate with a distinct columellar fold.
• Coloration: Shells are typically translucent to whitish, though variation may occur.
• Ecology: Members of Pyramidellidae are ectoparasites, feeding on the bodily fluids of other invertebrates (often annelids or other mollusks) using a specialized proboscis. Specific host relationships for O. mendozae have not been documented.

Accurate information on detailed morphological measurements, soft‑body anatomy, and precise ecological interactions for Odostomia mendozae is not confirmed in publicly available references.
