The species lives in deeper water than its congeners, in circalittoral habitats such as maerl beds. Grazer. Original taxon: Cerithium lacteum. Synonyms: algerianum, niveum.
31m deep, on sand, off Cala Cinque Denti, northern coast of Pantelleria island, Canale di Sicilia. 5,5mm.
Differences with the other species of Bittium: no varices, and 3 strong spiral ridges at the base of the shell, instead of 6 weaker ones in latreillii or reticulatum. Hence, special Bittiinae from NW. Europe, such as pale B. latreillii or B. reticulatum can be more easily separated from B. lacteum, whose range, anyway, does not extend north of the lusitanian coasts.
40-45m deep, in sand, at the foot of the Dente del Diavolo, Scilla, Calabria, SW. Italy. 6,5mm.
