微鞭毛、异养鞭毛虫[Ochromonas wyssotzki，Parapapromonas vestita，Pseudobodotremulans，Monosiga sp.，奇异放线单胞菌（Actinomonasmirabilis）和黑色侧单胞菌（Pleuromonasjaculans）的描述，特别提到了摄食机制和功能形态。两种不同类型的食品颗粒浓度的机制被发现：过滤和直接影响。这两种机制都依赖于水流的产生。粗略的模型表明，至少在某些情况下，所描述的机制可以解释实验确定的清除率值，生物体可以在海水中发现的细菌浓度的基础上生存。理论上的考虑和以前的实验结果表明，溶解的有机物质的吸收在自然界中对这些生物体起任何作用是非常不可能的。所研究的大小范围（3-7 μ m）的生物体构成了浮游食物链中细菌和较大的食食性生物体之间的必要联系。
Nanoplanktonic, heterotrophic flagellates [Ochromonas wyssotzki, Paraphysomonas vestita, Pseudobodo tremulans, Monosiga sp., Actinomonas mirabilis and Pleuromonas jaculans] are described with special reference to feeding mechanisms and functional morphology. Two different types of food particle concentration mechanisms are found: filtration and direct impact. Both mechanisms depend on the creation of water currents. Crude models show that at least in some cases, the described mechanisms can explain experimentally determined values of clearance and that the organisms may subsist on the basis of bacterial concentrations found in seawater. Theoretical considerations and previous experimental results render it very unlikely that uptake of dissolved organic material plays any role for these organisms in nature. Organisms of the studied size range (3-7 .mu.m) constitute a necessary link between bacteria and larger phagotrophic organisms in planktonic food chains.
