Range Description

Range "..during the summer in the immediate offshore waters from the Sanriku coast of Honshu, northward and eastward along the Kurilskiye Ostrova (but not into the Sea of Okhotsk) and the southern side of the Aleutian Islands, around the Gulf of Alaska, and southeastward as far as central Baja California. They do not go north of the Aleutian Islands, except rarely in the far southeastern corner of the Bering Sea. In the winter they are found regularly from southern Honshu south to Ogasawara Gunto [=Bonin Islands], Ryukyu Retto, and Taiwan, in the western Pacific, and south at least to Nayarit, Mexico, on the eastern side; there are a few records that season in the tropical mid-ocean waters."
