Ectoparasite of ophiuroids Ophiotrix fragilis (Abildgaard in O.F. Müller, 1789), Ophiactis balli (Thompson, 1840) and Ophiopholis aculeata (Linnaeus, 1767) – cf. Warén, 1983 – in the infralittoral (« low water mark at Jersey » in Jeffreys, 1867) down to the continental shelf and slope.

A similarly patterned Eulimid was recorded from Canarias, but its shell bears visibly convex teleoconch whorls, a distinctly angulated last whorl, a larger base, and the aperture is less narrow. Regarding d’Orbigny’s Eulima bifasciata from tropical western Atlantic, its shell is much more tapering.

According to Pero Ugarković’s observations, the animal is translucent white, with the eyes located on the roots of the cephalic tentacles, on top position and not on the sides.
