Soon after fertilization, we watch as two new sea urchin zygotes divide (mitosis) through eight cycles of synchronized division right up to the point of gastrulation. One can see the nuclei as dark spots in the 'green' cytoplasm. Scale bars and times are included, along with some strange sounds recorded in the deep. Imaged via dark-field microscopy. I apologize for the shaking in the middle - we had to add more sea water to prevent the slide from drying out.
