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 As a characteristic buried tellinid bivalve, Macoma balthica has a long inhalent siphon that enables it to feed in two different ways: deposit and suspension feeding.

Journal of Marine Research, 42, 957-968, 1984 The role of bacterial exopolymer and suspended bacteria in the nutrition of the deposit-feeding clam, Macoma balthica by Ronald W. Harveyl and Samuel N. Luomal ABSTRACT Potential nutritional contributions of bacterial exopolymer and suspended bacteria to the detritus feeding estuarine clam, Macoma balthica, were examined separately in laboratory Separation of solute and particulate vectors of heavy metal uptake in controlled suspension-feeding experiments with Macoma baZthica Ronald W.

Mature Macoma balthica are rarely over 25 mm long (Dunnill and Ellis 1969), but could be confused with the young of some of these larger clams. Other genera of Tellinidae (ie. Tellina sp.) have lateral hinge teeth (at least in the right valve); Macoma do not.

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.

Bu-rial depths of M. balthica were measured every three to four days until the clams' burial depth became stable. Feeding activities of the clams were observed for about ten minutes at irregular intervals for 22 times during the experiment.

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. Based on these observations, M. balthica was assumed to function as a suspension feeder on an exposed, sublittoral, sand Feeding Macoma balthica in NIOZ aquarium Brafield & Newell (1961), Gilben (1977) and Kamermans & Huitema (1994) recorded for M. balthica a maximal feeding radius of 4, 6 and 5 cm, respectively, close to present values. Lin & Hines (1994) mentioned a maximal radius of 10 cm, but their data referred to the larger American M. balthica up to 39 mm long. 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.

abundance was reduced by both Mya arenaria and Macoma balthica, with the greatest decline feeding bivalves may be maintained through interactions. Limecola balthica, commonly called the Baltic macoma, Baltic clam or Baltic tellin , is a small Through the siphons, it feeds on organic matter on the sediment surface or in the water.

Y1 - 1996 Feeding Macoma balthica in NIOZ aquarium The deposit-feeding behavior of Macoma balthica (L.) (Bivalvia: Tellinacea) is described relative to its role in sediment modification and the sedimentation cycle of Adams Cove, New Hampshire. Two size classes of M. balthica were selected for laboratory and field investigations of feeding behavior, sediment ingestion, sediment turnover, and Feeding activities of the clams were observed for about ten minutes at irregular intervals for 22 times during the experiment. The number of M. balthica exhibiting de posit or suspension feeding behavior was recorded. Bu rial depths ofM. balthica were measured every three to four days until the clams' burial depth became stable. Behavior has a predictive power that is often underutilized as a tool for signaling ecological change.
