Mikrokinematographische Aufnahmen der Entwicklungsstadien sowie Freiwasseraufnahmen von Medusenschwärmen. Gezeigt werden, z.T. in Zeitraffung, die Differenzierung befruchteter Eier zu Planulae, sowie Brutpflege und Festsetzung der Planulae am Substrat. Morphogenese der Planula zum Scyphistoma und vegetative Reproduktion durch Stolone, Knospung, Podocysten, Längsteilung und Strobilation. Entwicklung der Ephyra zur Meduse, Differenzierung des Gastrovascularsystems und der Gonaden.
