 note = {The internal sexual organs and reproduction of Chimaera phantasma caught in the coastal waters of Nagasaki were investigated. The testes of C. phantasma is that of seminiferous follicle type. The seminiferous follicles develop more in the region near the outer pole of the testis. Both ovaries are functional and each gonopores open separately without the cloaca. Some ova were covered in the capsule one by one at the nidamental gland, as in most Elasmobranchii, and the ova were spawned in succession in the same breeding season. Sexual maturity in females was apparently reached at a body length of about 63cm, while in males it was attained at about 51cm. The reproductive season of C. phantasma appears to last about a half year, with the peak activity during winter., 1975年から1980年まで長崎沿岸域より採集された408個体(雄・164,雌・244)のギンザメChimaera phantasmaの生殖器官の調査を行った.本種の生殖腺の発達過程は板鰓類のそれとは全く異なるが,生殖器官の形態・様式及び精子形式の過程等は極めてよく似ている.そこで,ギンザメの生殖について板鰓類と比較しながら述べた.本種の生殖腺は多くの板鰓類と異なり,雌雄とも又左右いずれも機能的である.雄は体長約51cm,雌は約63cmで性的成熟体長に達すると考えられる.産卵直前の卵は直径40mm以上にもなり,連続していくつかの卵をカプセルにつつんで産出する.産卵期は冬期を中心にして半年近くの長期にわたるものと考えられる., 長崎大学水産学部研究報告, v.51, pp.1-7; 1981},
