Feeding. While buried in the sand, the clam’s two siphons stick up above the surface. The longer siphon sucks in tiny bits of food lying on the Bay’s bottom. It can also draw in water and filter out plankton. Waste and unused water are ejected through the other siphon. Predators. Macoma clams’ long siphons look like worms crawling along the bottom.

Macoma balthica (L.), an abundant clam, ubiquitous in temperate estuaries across the North Atlantic, is known to practice both alternative basic modes of feeding available to seafloor invertebrates. It either holds its feeding organ, the siphon, at a fixed position just above the sediment surface to filter out food particles suspended in the overlying water or else extends and moves its siphon

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. Based on these observations, M. balthica was assumed to function as a suspension feeder on an exposed, sublittoral, sand

Deposit and suspension feeders can switch feeding behavior and show variations in feeding mode as individuals pass through life-cycle stages. Stable carbon and nitrogen isotopes were used to trace changes in diet of the tellinid bivalves M. balthica (facultative deposit feeder) and C. edule (obligatory suspension feeder), according to their size class.

Feeding behavior of Macoma balthica is influenced in the Neuse River estuary by both hydrodynamics and siphon-cropping by juvenile demersal fishes. Under conditions of identical concentrations of suspended particulates in the water column and organic contents of surface sediments, Macoma exhibited much higher levels of deposit feeding where currents were slower.

The surface deposit feeding speciesPygospio elegans andMacoma balthica are dominant members of many sandy bottom communities of northern boreal regions. The feeding mode of both species and the tube-building ofP. elegans are assumed to affect community structure by interactions with other species. The weight of tubes ofP. elegans varied between 2 and 13 g DW/100 cm2 at the two stations

One population, in a sublittoral, sheltered, muddy-sand sediment, is primar- ily deposit-feeding while the other population, in a sublittoral, wave-exposed, sandy sediment, is primarily suspension-feeding.
