. Cetaceans of the Channel Islands National Marine Sanctuary. Cetacea; Mammals. Beaked Whales of the Genus Mesophdon Five species of mesoplodonts are known from the eastern North Pacific, mostly from stranding records, as beaked whales are rarelv seen and positively identified alive at sea. Of those species, two are unknown from waters in or near the SCB - Stejneger's beaked whale, Miscplodon sltjncgen True, 1885, is not reported from south of Monterey and is apparently restricted to cold temperate and subpolar waters; and Blainville's beaked whale, M itnsirastns { BlainviUe m Desmarest, 1817)

Of those species, two are unknown from waters in or near the SCB - Stejneger's beaked whale, Miscplodon sltjncgen True, 1885, is not reported from south of Monterey and is apparently restricted to cold temperate and subpolar waters; and Blainville's beaked whale, M itnsirastns { BlainviUe m Desmarest, 1817), is known along the North American west coast only from single strandings m San Mateo County and San Francisco and is apparently ordinarily restricted to pelagic southern temperate and tropical waters. The other three species warrant only brief mention here, as they are not likely to be seen at sea except by the most diligent and persevering observers, or identified correctly at sea or on the beach e.xcept by specialists. Hubbs' beaked whale, M. carlhuhhst Moore. 1965, has been found stranded from British Columbia to San Diego, California and has been postulated to live in association with the confluence of the subarctic and California Current s\'stems, rarely if ever ranging north of the former's influence or south of the latter's. If this is in fact the case, Hubbs' beaked whales from the southern portions of the species' range in the eastern North Pacific might well be present in or near the SCB and CINMS at any time of year that the California current is flowing strongly near shore. The gmkgo-toothed beaked whale, M. ^inkgodcm Nishiwaki and Kamiya. 1958, is known in the northeastern Pacific from only two records, one from Malarimo Beach, Scammon's Lagoon, Baja Califor- nia and a second from Del Mar. California. The species .appears more common in the warm temperate and tropical waters of the western North Pacific and Indian oceans. Hector's beaked whale, M. hictori (Gray,
