1. Selenidium fallax的滋养体以高达35微米s-1的速率传播弯曲波，具有与真核纤毛和鞭毛所表现的相似的特征。0.12 - 0.15 Hz的拍频似乎是平均值，但也记录过超出此范围的频率。已观察到高达6微米s-1的平移运动。原生动物证明存在一个积极的弯曲机制，可能沿着其整个长度，并协调相邻的弯曲的手段。2.运动的雷诺数为10（-5）-10（-4），表明滋养体运动的流体动力学方面可以通过与纤毛和鞭毛相似的方法进行分析。3.这是可能的，原生动物表现出滑动微管机制，这可能是非常有用的相比，发生在纤毛轴丝。
1. The trophozoites of Selenidium fallax propagate bending waves at rates of up to 35 microns s-1, of a similar character to those manifested by eukaryotic cilia and flagella. A beat frequency of 0.12-0.15 Hz appears average, though rates outside this range have been recorded. Translatory locomotion at up to 6 microns s-1 has been observed. The protozoan demonstrates the presence of an active bending mechanism, probably along its entire length, and a means of coordinating adjacent bends. 2. The Reynolds number for the motion in 10(-5)-10(-4), suggesting that the hydrodynamic aspects of the trophozoite movement are amenable to analysis by similar means to those already employed for cilia and flagella. 3. It is possible that the protozoans exhibit a sliding microtubule mechanism, which could be very usefully compared with that occurring in the ciliary axoneme.
