Abstract

The chromosome numbers of five species in two families of Korea are investigated: Odontobutis platycephala, O. interrupta, and O. obscura in Odontobutidae, and Cottus koreanus and C. hangiongensis in Cottidae. In Odontobutis species, the three species showed the diploid chromosome number, 2n=44 (NF=44) telocentric chromosomes. In Cottus species, the mitotic chromosomes from 24 groups with two chromosomes each indicated that it is a diploid. The karyotype of C. koreanus and C. hangiongensis is 2n=48 and NF=52. These species is the first report on the chromosomes and the karyotype analysis except O. platycephala. Our findings provide cytotaxonomic evidence for the species distinctness of these five species whose descriptions were based primarily on external morphology.

한국산 동사리과 (Odontobutidae)의 동사리 (Odontobutis platycephala), 얼록동사리 (O. interrupta), 남방동사리 (O. obscura) 그리고 둑중개과 (Cottidae)의 둑중개 (Cottus koreanus), 한둑중개 (C. hangiongensis) 등 5종의 핵형 분석을 실시하였다. 동사리, 얼록동사리, 남방동사리의 염색체 수 및 핵형은 2n=44 (22T), NF=44였으며, 둑중개와 한둑중개의 염색체 수와 핵형은 2n=48(2ST+22T), NF=52로 밝혀졌다.
