Figure 1.

A DIC image of the poserior arm of the gonad. Oocytes are formed by budding from the syncytial gonad, each bud carrying a single nucleus. Oocytes develop in single-file, and oocytes at various stages of development are visible. Oocytes are fertilized upon entrance to the spermatheca. After leaving the spermatheca, embryos develop in the uterus awaiting expulsion through the vulva. We inject dyes into the syncytial gonad. After recovery, the fluorescence pattern of the dyes becomes that of figure 2.
