摘要: In teleosts, usually females have separated ovaries, but in some fishes the right and left ovaries are so completely fused as to give appearance of a single organ. The ovary connects body wall by short oviduct opens posteriorly anus. Eggs ovulated into ovarian cavities spawned with fluid out genital pore through during copulation. Males internal fertilization anal fin modified gonopodium (genitalium) introduce spermatozoa female tract; they do not penis. However, such copulation organ is found external fertilization.
