Ecrobia maritima is a species of very small aquatic snail, an operculate gastropod mollusk in the family Hydrobiidae. Description The size of an adult shell reaches 4 mm. Distribution Ecrobia maritima live in Pomorie Lake, a hyperhaline lagoon in eastern Bulgaria. Western Europe, Tunisia, the Peloponnesus and the Corinthian Gulf, all in the Ionian Sea, as well as — shockingly — the Black Sea coast in Romania, are habitats for E. ventrosa. Both the Black Sea and the Aegean Sea have been home to E. maritima. References Kevrekidis T., Wilke T. & Mogias A. (2005).
