| Research Abstract |
The evolutionary significance of intraspecific color variants in Scorpaeniformes fishes was investigated. In the genus Sebastes (Scorpaenidae), which has very complicate mating behavior due to the internal fertilization, genetic and morphological differences were evident among color variants. However, such differences were not found in the species without complicate mating behavior. These results suggest that the difference in body coloration may play an important role for assortative matings to keep a reproductive barrier in species with complicate mating behavior. The evolutionary significance of color variants may be closely related with the reproductive mode in species of Scorpaeniformes.
