Meiosis – egg cells under the microscope

These are some egg cells of sea urchins from a fixed microscopic preparation. They show different stages of cell division after the reproduction. Before the development of the larvae the embryo undergo up to 10 stages of division in hollow ball cell. I found only 4 in the sample. The eggs are fertilized outside the body and floated in masses into the water.
