Abstract

Fine structure of spermatozoa of the bastard halibut (Paralichthys olivaceus) is described. Its structure is characterized by acrosomeless, having a spherical head region and a small mid piece containing five mitochondria disposed one row. The flagellum inserts centrally on the nucleus and has lateral ribbons. The present study supports the suggestion that spermatozoal ultrastructure is of taxonomic importance and may be a phylogenetic criterion in teleostei.

한국산 넙치(Paralichthys olivaceus) 정자의 미세해부학적구조를 관찰한 결과 첨체가 없고, 두부는 둥글고, 중부는 작으며 단편모로 이루어져 있었다. 넙치정자의 구조는 경골어류의 일반적인 특징이나 형태 및 세포소기관의 미세구조에서 종간에 차이가 나타난다. 본 종의 정자는 5개의 미토콘드리아가 한 층으로 중편에서 중심립을 둘러싸고 있고, 말단부중심립과 관련된 9개의 구조물이 나타났다. 편모는 기부가 핵에 삽입되어 있고, 양측면으로 막이 확장되어 있었다. 이러한 특징은 경골어류의 종 분류와 계통학적 연구에 중요한 요소가 된다.
