See text Oenopota is a genus of sea snails, marine gastropod mollusks in the family Mangeliidae.

[3] In 1941 Paul Bartsch described species in this genus as having large, heavy and elongate -ovate to elongate- turreted shells.

The protoconch is smooth at the apex, succeeded by a whorl with three spiral cords and rather distantly spaced axial ribs.

The longitudinal ribs become stronger on succeeding whorls but evanesce at the base of the shell.

[4] Later, in 1980, it has been stated by Bouchet & Warèn that there is a high variation within the arctic forms of this genus, such as the outer lip showing all transitions from sinuated to nonsinuated [5] Oenopota is a boreal genus, with many species occurring in arctic and subarctic regions.
