Baltic Macoma (Macoma balthica)
Baltic macoma is a rather small mollusc. Most of these molluscs do not reach more than 3.5 cm in diameter. The shell of this bivalve mollusc is white or pinkish. If anyone has ever collected shells in sandy beaches, most of the findings could be macoma’s, since it is really abundant there.

It lives in the sea bottom not too far from the shore and prefers muddy and sandy substrates.

Macoma is a food source for diving ducks like Velvet scoter and for some fish species, which live in the same habitat as this mollusc.
