Published in: Systema Naturae, ed. 10: 1120. source: MolluscaBase. Synonym of Limecola Limecola balthica, commonly called the Baltic macoma, Baltic clam or Baltic tellin , is a small saltwater clam, a marine bivalve mollusk in the family Tellinidae (the macomas and tellins). Contents.

Habitat: Lives on fine sand and mud bottoms. From the intertidal zone down to several hundred metres. Distribution: A northern Atlantic, Arctic species. In Europe records from Iceland and Norway (Distr.

Spatfall of the tellinid bivalve Macoma balthica may occur in fine-grained sediments at different tidal elevations in the Wadden Sea. but it is not clear which mechanism (active habitat selection or passive sinking of larvae, or both) can explain the observed distribution pattern. Spatfall and the subsequent development of juvenile abundances and size distribution were studied along a transect

75 As an example, the Baltic clam, Macoma balthica (Linnaeus, 1758) (Bivalvia: 76 Tellinidae), is an infaunal tellinid bivalve commonly present in marine and estuarine 77 soft-bottom habitats of the northern hemisphere. As an important prey for migratory 78 birds (Piersma and Beukema, 1993), macro-invertebrates (Edjung and Bonsdorff, 1992) Our results suggest that in shallow habitats, production from Fucus vesiculosus is the primary energy source for M. balthica.

In the muddy-sand, I varied adult densities from 250 (% normal field density) to 4000 (4 X hi. balthica and thus define the optimal habitats for its successive life stages. MATERIAL AND METHODS Detailed data on distribution patterns of Macoma balthica are available from along- term samDlino uroaramme ~started around 1970)of the macrozoobenthos at: I5 Derma- In estuarine areas, bivalve species can be found in a variety of environments, where they experience large differences in environmental conditions.
