This paper, although it does not mention Meraenaria (Venus) meraenaria 

 specifically, is an extensive review of the literature on filter feeding, 

 mostly published since the review by Yonge (1928) . It contains important 

 generalizations that apply to lamellibranchs as a group. Gills of suspension- 

 feeding lamellibranchs propel and filter water. Most investigators have 

 assumed that filtration is performed mainly by latero-f rontal cilia of the 

 gill filaments, but MacGinitie stated that during normal feeding water is 

 filtered through sheets of mucus on gill surfaces. A variety of sorting 

 devices, especially on gills, has been developed in different species. 

 Sorting is performed according to size, shape, and density of particles. 

 Qualitative sorting has been demonstrated in oysters. - J.L.M. and M.W.S.

In stomachs of veligers of M. meraenaria Carriker (1961) did not observe 

 freshly consumed food particles larger than 1-2 p, but veligers of 0. edulis 

 seemed to remove flagellates of 2-10 u more efficiently from water than those 

 of 1-2 u (Cole 1937) . V. meraenaria cleared suspensions of a minute green 

 alga and a small diatom at low rates (Rice and Smith 1958) ; rates of water 

 transport were not measured. In natural surroundings V. meraenaria remains 

 open about 90% of the time at suitable temps (Loosanoff 1939) . V. striatula 

 cleared suspensions of the alga Phaeodactylum at low rates. Rate of water
