Feresa attenuata Gray, 1874 p.238; Type locality- South Seas; Kim et al., 2000 p.88; Kim, 2004 p.239.
Range: Since F. attenuata rarely enters the waters of Korea, vagrant might better fit the distribution status of this species (Fig. 96).
Remarks: The pygmy killer whale is a monotypic species with low genetic diversity across its range (Burbidge et al. 2012).
