Abstract
Fadenwurm. Labronema sticht seine Beutetiere an, in diesem Fall den saprozoisch lebenden Nematoden Panagrellus redivivus, und saugt sie aus. Funktion des vorderen Saugapparates, solange der Räuber mit seinem Mundstachel Probestöße ausführt. Vorgänge während der Nahrungsaufnahme, insbesondere die Pumptätigkeit des Ösophagus.
The film shows at predominantly normal speed (24 f/s) and partially at high magnification the predatory activities of the nematode Labronema spec. which punctures and then sucks out its prey (in this case the saprozoic nematode Panagrellus redivivus). Emphasis is placed initially on the function of the anterior feeding apparatus as long as the predator probes its punctured prey with searching stylet movements. Later the film concentrates on processes during ingestion, especially on the pumping activity of the oesophagus which is mainly shown at moderately slow motion (50 and 100 f/s).
