Ultrastructural features of the ovary and oogenesis in the
polychaete Capitella jonesi (Hartman, '59) have been described. The ovaries are
paired, sac-like follicles suspended by mesenteries in the ventral coelom
throughout the midbody region of the mature worm. Oogenesis is unsynchronized
and occurs entirely within the ovary, where developing gametogenic stages are
segregated spatially within a germinal and a growth zone. Multiplication of
oogonia and differentiation of oocytes into the late stages of vitellogenesis occur in
the germinal region of the ovary, whereas late-stage vitellogenic oocytes and
mature eggs are located in a growth zone. Follicle cells envelop the oocytes in the
germinal zone of the ovary and undergo hypertrophy and ultrastructural changes
that correlate with the onset of vitellogenesis. Florida Atlantic University.
