  • ABSTRACT

    Two specimens of Bathyraja smirnovi (381 mm and 673 mm in total length), belonging to the family Arhynchobatidae in the order Rajiformes were collected from the eastern coast of Korea using trawls and gill nets in 2011 and 2014. These specimens exhibited distinct morphological characteristics, including small denticles distributed only along the edge of the disc and mid-dorsum, and the absence of a complete row of med-dorsal thorns. Morphologically, B. smirnovi closely resembles B. bergi, B. isotrachys, and B. simoterus. However, it could be distinguished from B. bergi by the limited distribution of denticles along the edge of the disc and mid-dorsum. Additionally, it differs from B. isotrachys in the presence of scapular thorns and from B. simoterus in the absence of mid-dorsal thorns. The Korean name 'Geum-ga-o-ri' for B. smirnovi was adopted in this study, as proposed by Kim and Ryu (2016).
