Change of the Scientific Name for Piked Dogfish in Korea to Squalus suckleyi (Squalidae, Chondrichthyes) Based on Morphological and Molecular Comparisons of Squalus acanthias from New Zealand

摘要

Squalus acanthias has been considered the valid scientific name for piked dogfish by many taxonomists, although others recognize two valid species, Squalus suckleyi and S. acanthias, based on differences in the numbers of precau-dal vertebrae and their distribution. We compared Korean piked dogfish with S. acanthias from New Zealand using morphological and molecular methods to elucidate the taxonomy. The Korean piked dogfish was distinguished from S. acanthias from New Zealand by the number of precaudal vertebrae (70-75 in the former vs. 77-80 in the latter) and 540 base pairs in the mitochondrial DNA cytochrome c oxidase subunit I sequence (genetic distance: 0.007-0.013). Therefore, we suggest that the scientific name of the Korean piked dogfish bechanged from S. acanthias to S. suckleyi.
