Oceanida is a genus of very small parasitic sea snails, marine gastropod mollusks or micromollusks in the family Eulimidae.[1]
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.[2]
