Definition
Scissurella obliqua is a species of minute marine gastropod mollusk belonging to the family Scissurellidae, commonly known as the slit snails.
Overview
Members of the genus Scissurella are characterized by very small, often translucent shells that possess a distinctive slit or foramen along the outer lip, a feature that gives the family its common name. S. obliqua is part of this group of micromollusks, inhabiting marine environments. Detailed information on its specific habitat range, ecological role, and abundance is limited in publicly accessible scientific literature.
Etymology / Origin
The generic name Scissurella derives from the Latin scissura, meaning “cleft” or “fissure,” referencing the shell’s slit. The specific epithet obliqua comes from Latin obliquus, meaning “slanting” or “oblique,” possibly alluding to an angled aspect of the shell’s morphology as perceived by the original describer.
Characteristics
- Shell size: Typically measures only a few millimeters in maximum dimension, consistent with other scissurellid micromollusks.
- Shell morphology: Expected to exhibit the family’s hallmark slit or foramen; the term obliqua suggests that the slit may be positioned at an oblique angle relative to the shell’s axis.
- Surface sculpture: While many Scissurella species display fine axial ribs or growth lines, specific sculptural details for S. obliqua are not well documented.
- Soft anatomy: General scissurellid anatomy includes a radula equipped for grazing on microalgae, but species‑specific anatomical data for S. obliqua are unavailable.

Note: Precise distribution, detailed morphological description, and ecological data for Scissurella obliqua are not comprehensively recorded in readily available taxonomic references; thus, some aspects of this entry rely on general characteristics of the genus and family. Accurate, species‑specific information is not confirmed.
