 note = {Male and female reproductive systems of the spiny lobster Panulirus japonicus were
studied anatomically. Development of the ovary was observed histologically to classify its
maturation process of the oocyte. The reproductive system of the males consisted of the
testis, vas deferens and spiral-shaped genital apparatus which was provided externally.
For the females, the ovary and oviduct were its components. The ovary showed a H-shape,
and reddish orange at the matured condition. The vas deferens and ovary changed their
size on each reproductive cycle. Oocytes in the ovary were classified into three phases,
based on the condition of vitellogenesis. They were further divided into six stages from
differences of the diameter and cytoplasmic characters. Furthermore, the eyestalk ablation was conducted. Based on the results of the operation, physiological interference of
the eyestalk in the maturation was discussed.},
