[Assessment of cilium force on the foot sole of the freshwater snail Lymnaea stagnalis].

In this study, we evaluated the force of the cilium on the foot sole of a medium-sized pond snail Lymnaea stagnalis, crawling up in the anaerobic water. It was found that there are 1.3 x 10(9) cilia on the foot sole, their force is 1.47 x 10(-6) W, the force of one cilium is 1.1 x 10(-15) W and the force of single ciliary beat is 1.1 x 10(-16) W.
