Two stranded whales were found dead on the coast of Jeju, South Korea. Based on the outer appearance and autopsy findings, one was determined to be an adult and the other a calf. The carcasses were dissected for species identification and pathological examination. A genetic analysis was performed, and the morphological characteristics of the skull observed. Then, 448 bp of the 5' half of the mitochondrial (mt) DNA control region and 413 bp of the mtDNA cytochrome b gene were sequenced. A BLAST search revealed that the whales were ginkgo-toothed beaked whales (Mesoplodon ginkgodens). Morphological comparison of the adult skull with the holotype specimen confirmed the result. This is the first record of a stranded ginkgo-toothed beaked whale in Korea.
在韩国济州岛海岸发现两头搁浅死亡的鲸鱼。根据外观和尸检结果，确定一头为成年鲸鱼，另一头为幼鲸。对尸体进行解剖以进行物种鉴定和病理检查。进行了基因分析，并观察了头骨的形态特征。然后，对线粒体（mt）DNA控制区5'端的448bp和mtDNA细胞色素b基因的413bp进行了测序。BLAST搜索显示这些鲸鱼是银杏齿中喙鲸（Mesoplodon ginkgodens）。将成年鲸鱼的头骨与正模标本进行形态学比较，证实了这一结果。这是韩国首次记录到搁浅的银杏齿中喙鲸。
