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.
两种苔藓虫物种的摄食率随颗粒大小和流速而变化。在其中一个物种中,流速增加会减少对较大颗粒的摄食。两种物种中较小的那个对最大颗粒的异常高捕获率表明,其摄食方式从通过纤毛流摄食转变为涉及高度触手活动的摄食。这是对底栖无脊椎动物在交替模式下摄食的首次量化,表明触手摄食可能为苔藓虫提供重要的营养来源。
