초록

시각세포는 많은 종에서 알려지지 않았지만 종의 서식환경과 매우 밀접한 연관성을 같는 것으로 알려져 있다. 이에 흰줄납줄개와 각시붕어 두 종의 시각세포를 광학현미경으로 조사하였다. 두 종의 눈은 비교적 큰 것으로 확인되었다. 신경연합층은 가장 바깥쪽부터 망막색소상피층, 시각세포층, 외핵층, 외망상층, 내핵층, 내망상층, 신경절세포층 등으로 구성된다. 특히 시각세포들이 존재하는 시각세포층을 확인한 결과, 매우 다양한 시각세포들을 보유하고 있었다. 긴 단일원추세포, 짧은 단일원추세포, 길고 짧은 원추세포가 쌍을 이룬 이형이중원추세포와 간상세포로 구성되어 있었다. 이들의 수평단면을 확인한 결과, 열 배열의 형태로 나타났으며 다양한 시각세포 종류와 열 배열을 갖는 특징은 이들의 서식환경과 밀접한 연관성이 있는 것으로 확인되었다.

Two Korean Rhodeus bittering fishes are known as having a unique reproduction system that the female deposits its egg inside freshwater mussels. Among them, R. ocellatus and R. uyekii show an ecological difference in feeding items and micro-habitat. Through a light microscope, the visual cells of the retina in the two species were investigated to get information between vision and environment related with habitat. The two fishes' eyes are spherical and R. ocellatus has relatively larger eyes. For the two species, the visual cells of the retina consisted of long single cones, short single cones, unequal double cones and rods. In the cones, all show a row mosaic pattern. Although the two species have a different micro-habitat in the wild, the component of the visual cells was very similar to each other.
