Lecture notes on penaeus reproductive system

Penaeus Female Reproductive System:

The female has a pair of long ovaries extending the whole length of the thorax and the abdomen along the median line. The two ovaries are fused together posteriorly, but free anteriorly. Near the anterior end the ovaries produce finger-like outgrowths called diverticula. From each ovary arises an oviduct.The oviduct opens to the third walking leg.

Penaeus_Male Reproductive System:The male has a pair of tubular testes located in the thorax on either side of the middle line. The two testes are fused together anteriorly.Each testis has many finger-like outgrowts called diverticula. Posteriorly, the testis leads into a vas deferens. The terminal end of the vas deferens becomes dilated into an ejaculatory bulb. The ejaculatory bulb opensbto the outside by the male genital pore at thevbase of the last walking leg.
