Abstract
The aim of the present study was to investigate with transmission electron misroscope the comparative morphology of epididymal spermatozoa in two species of the Korean insectivorous bats belonging to 'prolonged sperm storage' type (Rhinolophus ferrumequinum korai) and 'delayed implantation' type (Miniopterus schreibersi fuliginosus). Sperm head of the R. ferrumequinum korai was bullet shaped and that of M. schreibersi fuliginosus was spatula shaped. The nuclei of the sperm head of the R. ferrumequinum korai and M. schreibersi fuliginosus occupied two-third and a half of it, respectively. The segmented columns of R. ferrumequinum korai were about 12 to 14 in number, and those of the M. schreibersi fuligincsus were about 10 to 12. Particularly, a pile of the satellite fibers in middle piece of R. ferrumequinum korai remained the inner aspect of the outer dense fibers, but those of the M. schreibersi fuliginosus were not.
본 연구는 정자저장형에 속하는 한국산 관박쥐와 지연착상형에 속하는 한국산 긴가락박쥐 정자들의 형태를 각각 비교 관찰하였다. 정자두부의 형태에 있어서, 관박쥐는 긴 탄환형이었고, 긴가락박쥐는 주걱형이었다. 관박쥐는 두부의 2/3부분이 핵으로 이루어져 있었고, 긴가락박쥐는 1/2부분이 핵으로 이루어져 있었다. Segmented column들은 관박쥐의 경우
