Range: Stranding and by-catch of Stejneger’s beaked whales have mostly occurred along the east coast of southern Gangwon Province and Gyeongsangbuk Province ( Fig. 87 ). The population in the East Sea has likely become isolated from the Pacific Ocean ( Loughlin & Perez 1985 ). Few observations of the species have occurred during marine surveys in Korea (Cetacean Research Institute 2007) . Remarks: Although isolated populations reside in the East Sea, the taxonomic status of the population remains uncertain.
