J. Appl. Ecol. 22: 395–405. Fog, K., Schmedes, A. We found that, depending on species-specific traits, deposit-feeding macrofauna an amphipod, monoporeia affinis , a bivalve, macoma balthica and an invasive both suspension- and deposit-feeding modes (Brafield & Newell 1961; Bubnova 1972). According to Bubnova, M. balthica filter feeds when suspended food material is abundant and begins deposit feeding as the food supply decreases.

Highest frequencies of yellow shells are found in northeastern Atlantic Macoma (Beukema & Meehan, 1985), ironically called M. balthica ‘rubra’ (ruber is Latin for red). Limited information is currently available on metal ENP effects, uptake, and depuration kinetics in aquatic organisms.

Results from this study were compared to 28-day bioaccumulation experiments involving PCB-contaminated sediment from Hunters Point Naval Shipyard (San Francisco Bay, CA) and the clam Macoma balthica. Due to differences in feeding strategy, M. balthica deposit-feeds whereas C. fluminea filter-feeds, the relative importance of the aqueous uptake route is predicted to be much higher for C Contrasting influences of suspension-feeding and deposit-feeding populations of Macoma balthica on infaunal recruitment @article{lafsson1989ContrastingIO, title={Contrasting influences of suspension-feeding and deposit-feeding populations of Macoma balthica on infaunal recruitment}, author={E. {\'O}lafsson}, journal={Marine Ecology Progress Series}, year={1989}, volume={55}, pages={171-179} } Barite, an important component of offshore drilling muds, is shown to adversely affect the ctenidia of the suspension feeding bivalve, Cerastoderma edule and the deposit feeder, Macoma balthica.

Other genera of Tellinidae (ie. Tellina sp.) have lateral hinge teeth (at least in the right valve); Macoma do not. Macoma are generally more rounded and more inflated than Tellina; Macoma are smooth The feeding radius of M. balthica and S. plana is a linear function of shell size.
