(...) The finless porpoise (Neophocaena phocaenoides) is found in the Inland Sea of Japan (Kasuya and Kureha 1979), but has not previously been confirmed to occur in the southwestern part…
Two hundred and eighty-nine skulls of Dall's porpoises from the North Pacific Ocean, Sea of Japan, Sea of Okhotsk, and Bering Sea were investigated morphometrically. A clear pattern of geographic…
Aerial surveys covering 5117 linear kilometers were conducted at 91 and 183 m altitude under optimal sighting conditions in an area north of Fyn, Denmark, and in the Bay of…
(...) The finless porpoise (Neophocaena phocaenoides) shows a decidedly inshore distribution pattern (Kasuya and Kureha 1979), occurring in coastal waters frequented by fishermen. Its lack of a beak and a…
A study of Dall's porpoise distribution and behaviour between September 1986 and February 1989 confirmed the year-round presence of these animals in Monterey Bay, California. Dall's porpoises in the Bay…
Results of nine whale sighting cruises in the Japanese coastal waters in 1983 through 1986 and some additional cruises provided following conclusion. Dall's porpoises inhabit waters below 24°C, but the…
Results of an aerial sightings survey conducted in coastal (within the 600m depth contour) Icelandic waters from 27 June-20 July 1986 are presented. The survey followed a predetermined random grid,…
