Scepanotrocha simplex: when creeping the whole body is covered by a peristaltic movement going forwards and backwards, which I haven´t observed in other rotifers. The food pills are moved like going through a funnel, which bears resemblance to the movement of the colorless Euglenoid flagellate Astasia klebsii.(2)
