Abstract

German
Aurelia aurita. Die Planulalarven verlassen die Mundtaschen der Medusen, schwimmen umher und gehen zur sessilen Lebensweise über. Sie entwickeln sich zu Polypen, die ungeschlechtlich weitere Polypen bilden und schließlich strobilieren. Die abgeschnürten Ephyren leben pelagisch und wachsen zu geschlechtsreifen Medusen heran.

The Life cycle of the moon jelly covers the metagenetic development with two generations: the pelagically living medusa having sexual propagation and the benthically living polyp having asexual propagation producing the medusa through transversal fission. This developmental mode is presented in the film in its basic characteristics: Adult medusa - planula larva - polyp (Scyhistoma) - asexual propagation by stolons - asexual propagation by transversal fission (strobilation) - young medusae (ephyra and metephyra) - adult medusa.
