Ziphius cavirostris G. Cuvier, 1823 p.350; Type locality- France; Kim et al., 2000 p.78; Kim, 2004 p.234.
Z. grebnitzkii Stejneger, 1883 p.77; Type locality- Commander Islands, Bering Sea, Russia.
Range: No official records verified strandings or by-catch of Cuvier’s beaked whales from the waters of Korea. However, molecular investigations confirmed that the meat of Z. cavirostris was sold at markets in Korea (Dalebout et al. 2005). Since a federal law in South Korea prohibits the import of whale meat from other countries or deep-sea fisheries, there is high probability that the meet of Z. cavirostris in markets was poached from Korean waters (Fig. 85).
Remarks: Despite regional variation in morphology (Dalebout et al. 2005), Z. cavirostris is considered a monotypic species.
