Pike and MacAskie (1962) report three strandings along the British Columbia coast and Mead et al. (1982) recorded four others. One sighting of a small whale by Hubbs (1946) off La Jolla, California, is the only posible sighting of a live animal. The range appears to extend west to Japan where the species has been recorded from the northeast coast of Honshu at about 38°N latitude (Mead et al. 1982). The range appears to be south of that of Stejneger's Beaked Whale and north of that of Mesoplodon ginkgodens, the Ginkgo- Toothed Beaked Whale (Watson 1981). Protection International: Mesoplodon species are included in Appendix II of the Convention on International Trade in Endangered Species (CITES). No other international agreements refer to the genus. The species is listed as 'Indeterminate' in the Red Data Book (Goodwin and Holloway 1972). National: The genus is protected by general legislation in several countries but no specific provi- sions are known. In Canada, general protection is accorded under the Fisheries Act and the Cetacean Protection Regulations which prohibit commercial whaling. In the United States, general protection is accorded under the Marine Mammal Protection Act of 1972 and the Endangered Species Act. Population Sizes and Trends Known only from 31 stranded specimens and one possible live sighting, this species can only be described as rare. The species is not known to have been commercially exploited or captured (Mitchell 1975). No other information is available on population status. Habitat The distribution of Mesoplodon carlhubbsi along the Japanese coast appears to coincide with the surface Transition Domain and at depth with the Subarctic Current System where deep elements of the Kuroshio and Oyashio currents mix
