Abstract Nach Eindringen der Spermatozoen in das Ei werden die Richtungskörper gebildet und abgeschnürt. Entwicklung des Eies über spiralige Furchung und Invagination zur Trochophora-Larve. Vom 128-Zellenstadium bis zum Schlüpfen der Trochophora rotiert die Larve in der Eihülle. Habitus der Trochophora-Larve. Aufgenommen mit 16 B/s; Vorführgeschw. 18 B/s.
After penetration of the spermatozoa into the egg the polar bodies are formed and seperated. Development of the ovum by spiral cleavage and invagination into the trochophora larva. From the 128 cell state until the hatching of the trochophora the larva rotates in the embryonic membrane. Habitus of the trochophora larva. Recording speed 16 fps, projection speed 18 fps.
