Abstract Dinoflagellat. Entwicklung von acht mondsichelförmigen Sekundärzysten aus einer kugelförmigen Primärzyste, Entstehung von meist fünf bis acht zweigeißeligen Zoosporen (Dinosporen) in jeder Sekundärzyste, Freiwerden der Dinosporen, Enzystierung einer Dinospore.
The peridinian Dissodinium lunula is a cosmopolite of marine coastal plankton. It multiplies vegetatively by multiple fission. At first, from a spherical primary cyst eight lunate secondary cysts develop. Finally, from each of these five to eight biflagellated zoospores usually arise. D. lunula has a large nucleus, whose numerous chromosomes become clearly visible already in vivo. As to the observation of the nuclear division young uninucleated secondary cysts were best appropiate.
