(...) Amano and Miyazaki (1996) found a geographic difference in the size of the white flank patch among dalli-type animals and reported that porpoises from the Sea of Japan-Okhotsk population…
Age, growth, and reproductive patterns of Dall’s porpoise (Phocoenoides dalli) in the central north Pacific ocean
Ferrero, Richard C.; Walker, William A.
Marine Mammal Sci (1999)
Life history parameters were estimated for Dall's porpoise, Phocoenoides dalli, from biological specimens collected in the western Aleutian Islands, during 1981–1987. Of 2,033 males and 3,566 females examined, reproductive data…

Journal of Cetacean Research and Management (1999)
Cephalopod prey were identified from the stomachs of 100 Dall's porpoise (Phocoenoides dalli) incidentally taken by commercial salmon gillnets and research vessels from 1978 to 1982 in the western North…

Canadian Journal of Zoology (1998)
A 60-cm female fetus recovered from a Dall's porpoise (Phocoenoides dalli) found dead in southern British Columbia was fathered by a harbour porpoise (Phocoena phocoena). This is the first report…
Diurnal feeding by Dall’s porpoise, Phocoenoides dalli
Amano, Masao; Yoshioka, Motoi; Kuramochi, Toshiaki; Mori, Kyoichi
Marine Mammal Sci (1998)
(...) It has been hypothesized that Dall's porpoises forage mostly at night or at dawn, because porpoises taken in the morning tended to have a larger amount of food remains…
