| Adineta cf acuticornis, feeding behavior; in the literature the function of the rake apparatus is described as a tool for scraping off bacteria or other diet from the substrate Adineta is gliding on. But this may be an artefact, because in nature it is very unlikely that Adineta is gliding on a substrate like the glass of the microslide. If one observes Adineta with binoculars in the natural habitat one can see this critter gliding around smaller particles like the one here. The backward movement of the cilia would move the particles away, but the denticles of the rake apparatus are the counterpart of the cilia movement so that the particle is permanentely turned around, so that Adineta can wipe of bacteria from the particle.
