This paper presents scaling equations relating suspension-feeding rates to body size for articulate brachiopods and bivalve molluscs, two classes which represent a significant component of the fossil record of marine benthic communities. Clearance (feeding) rates of five species of living articulate brachiopods and three species of epifaunal suspension-feeding bivalve molluscs collected from mid-latitude fjords of Newfoundland and New Zealand were measured in similar experimental conditions. In comparisons within and between the two classes, we found that both plectolophous and spirolophous brachiopods had significantly lower feeding rates than mytilids, which are filibranchs, but that a sympatric primitive eulamellibranch veneroid bivalve had rates comparable to the brachiopods. Articulate brachiopods do not appear to feed effectively at the high algal concentrations which bivalves can exploit. The data on comparative suspension-feeding rates support the hypothesis that past changes in diversity and distribution of bivalves and brachiopods may be related to an overall increase in energy flux and escalation of metabolic rates during the Phanerozoic.

The structure, ciliation, and function of the lips of 12 species belonging to nine families of the subclass Pteriomorphia are described. All these species have devices for preventing the swallowing of excess water, collected along with participate food material, by the ctenidia and palps. It is suggested that in all bivalves, as in other suspension-feeding animals, water currents are generated by the food-collecting apparatus. But, whereas in members of the echinoderm superphylum, the development of gill slits to allow the escape of excess water which has already entered the mouth has had great evolutionary implications, the escape of water before it gets to the mouth is usually achieved in a less conspicuous manner in bivalves, although a complex lip apparatus has been developed in some monomyarian members of the Pteriomorphia.

Extensive studies have dealt with the transport of particles on the gill of suspension feeding bivalves, but our knowledge of the mechanisms involved is still incomplete. There is, however, physiological evidence that each of the ciliated cell systems in bivalve molluscs may be individually controlled. Three types of ciliated cells are distinguished on the gill of fingernail clams: frontal (FC); latero-frontal (LFC); and lateral (LC).For the most part in studies involving ciliary control mechanisms, LFC are neglected. It is thus the purpose of this study to present data which begin to elucidate a neuronal mechanism for LFC control.Gill preps were isolated with an intact nerve supply in a dish which was placed in a holder fastened to an adjustable stage of a microscope. In fields of view of 50 gill filaments, ciliary motility, chemical perfusion and electrical stimulation were observed and/or performed.
