Abstract Die Organismen des Planktons sind definitionsgemäß nur eingeschränkt zu Ortsveränderungen aus eigenem Antrieb in der Lage. Basierend auf der großen Formenvielfalt haben sich sehr unterschiedliche Fortbewegungsweisen entwickelt, ebenso wie zahlreiche morphologische und physiologische Anpassungen zur Aufrechterhaltung des Schwebezustandes. Zur Fortbewegung nutzen viele kleine Planktonorganismen und v. a. Larven Wimpern (Cilien), die in Feldern oder Bändern angeordnet sind. Der Körper der sogenannten Müllerschen Larve der Turbellaria ist vollständig mit Cilien besetzt. Neben der Fortbewegung erfüllen diese Cilienbänder bei Larven meist noch eine weitere Funktion: das Herbeistrudeln von Nahrung und den anschließenden Transport zum Mund.

Planktonic organisms have by definition only limited capabilities for locomotion. Due to the vast diversity of planktonic taxa belonging to all biotic kingdoms, very diverse ways of locomotion have evolved as well as a variety of morphological, and physiological adaptations for buoyancy regulation. Many small plankton organisms, particularly invertebrate larvae, use cilia for their locomotion, which are often arranged in fields or bands. The body of the so-called Müller's larva of the turbellarians is completely covered by cilia. Besides locomotion, bands of cilia also serve other functions, as in the collection of food particles and the subsequent transport to the mouth.
