Oceanida is a genus of very small parasitic sea snails, marine gastropod mollusks or micromollusks in the family Eulimidae.

This genus was described by Léopold de Folin in 1870. These are subtidal snails that are parasitic on echinoderms. Their length varies between 2 and 3 mm.

Description

(Originally described in Latin as Spiroclimax) The shell exhibits a subcylindrical form, characterized by transparency and a suture that resembles a gently descending spiral staircase. The aperture displays an auriculate shape. The outer lip is thickened, featuring a sigmoidally margined profile that curves inward towards the suture. The columella is moderately thick, adorned with a funicular cord and exhibiting minimal plication. The protoconch is polished and positioned at a right angle.
