Movie#201. Sixteen cell stage Zebrafish embryo.

The first frame shows cells at metaphase. The sequence covers the next four cell cycles.

In each prophase, there is a rapid onset of yolk platelet motility. Yolk material is fragmented off the yolk cell and drawn into the outermost blastomeres through cytoplasmic bridges.

Frames were taken at 30 second intervals.
