PARTICLE SIZE AND FLOW VELOCITY INDUCE AN INFERRED SWITCH IN BRYOZOAN SUSPENSION-FEEDING BEHAVIOR
Abstract:
The feeding rates of two bryozoan species varied with particle size and flow velocity. In one species, increased flow reduced feeding on larger particles. The anomalously high capture rate of the largest particles by the smaller of the two species indicates a switch in feeding by ciliary currents to feeding that involves a high degree of tentacular activity. This is the first quantification of feeding under alternate modes in a benthic invertebrate and suggests that tentacular feeding may provide a significant source of nutrition for bryozoans.
