The reproductive biology of Sergestes similis (Decapoda, Natantia)

The reproductive biology of Sergestes similis (Decapoda, Natantia) 227 2 2 3 3 H. C. Genthe Jr. Department of Biological Sciences University of California at Santa Barbara Goleta California USA Abstract A study was made of the reproductive biology of Sergestes similis Hansen from the Santa Barbara Basin off the coast of southern California. It includes investigations of sex ratios, sexual dimorphism, and morphology of the reproductive system. Histological sections of the gonads revealed stages of gametogenesis, as well as an external criterion of sexual maturity in males. Determination of chromosome number and morphology was made using standard karyological techniques. The external genitalia are noticeably adapted for the transfer and maintenance of the spermatophore, and for the protection and transport of sperm during external fertilization. A few aberrant individuals show apparent sex reversal. Based on size-frequency records and internal examination of the gonads, a description of their reproductive cycle for 1967 is presented for specimens from the Santa Barbara Basin. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Marine Biology Springer Journals
