Oenopota pyramidalis, common name the pyramid lora, is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. ^[1]

Description

The length of the shell varies between 10 mm and 23.5 mm.

The shell has usually a rather high spire with seven or eight tolerably convex whorls, scarcely or not at all shouldered. It shows 13 to 16 sigmoid ribs, fading out about or above the middle of the body whorl. There are numerous, fine, close revolving lines, sometimes not apparent on the ribs. The color of the shell is pale chestnut, when fresh. The species varies considerably in the elevation of the spire and in ther^{[ clarification needed ]} stoutness, as well as in the development of the ribs. ^[2]

Distribution

This species occurs in European waters, the Northwest Atlantic Ocean, the Arctic waters of Canada, the Gulf of Maine. Fossils have been found in Quaternary strata of Iceland (age range: 0.126 to 0.012 Ma).
