It has a plump almost circular shell, up to 25 mm in length, with umbones close to the midline. The posterior of the shell may be very slightly tapered. feeding rate of knot. Unfortunately for knot, the majority of the preferred thin-shelled prey live out of reach of the bill, whereas the thick-shelled species live at the surface.

(1995) reported juvenile density 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.

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 of M. balthica were measured every three to four days until the clams' burial depth became stable.

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. 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.

The facultative deposit-feeding clam Macoma balthica is used as a bioindicator organism for assessing coastal metal contamination. Previous work has evaluated the assimilation of metals from different possible food sources for this clam, but no studies have measured the uptake rates of metals from different dissolved sources. T1 - Why do Oystercatchers Haematopus ostralegus switch from feeding on Baltic tellin Macoma balthica to feeding on the ragworm Nereis diversicolor during the breeding season?

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.

In aquaria, Macoma balthica burrowed to a depth of about 2 cm. and then extended the siphons. The inhalant siphon behaved much as in Tellina tenuis, reaching
