Abstract Das Sonnentierchen arretiert seine Nahrung mit Hilfe der Axopodien. Daraufhin umwächst ein glockenförmiges Ingestionspseudopodium das Beutetier. Wenn es umschlossen ist, setzt die Verdauung ein. Die Fangtechnik wird anhand elektronenmikroskopischer Befunde im Trick erklärt. Zeitraffung.
The heliozoan Actinophrys captures its prey with the help of axopodia. Ingestion takes place by the growth of a bell-shaped pseudopodium which gradually surrounds, and finally, completely encloses the prey. Digestion then occurs. These events are demonstrated in computer animation together with electron micrographs. Time-lapse.
