Marine Mammal Sci (2001)
Prevalence of the larval cestode, Phyllobothrium delphini, was estimated from 2,445 Dall's porpoise, Phocoenoides dalli, from the incidental take of the Japanese high seas salmon drift-net fishery in the northwestern…
Summer feeding habits of Dall’s porpoise, Phocoenoides dalli, in the southern Sea of Okhotsk
Walker, William A.
Marine Mammal Sci (1996)
Stomach contents were analyzed from 85 Dall's porpoises, Phocoenoides dalli, taken in the southern Sea of Okhotsk during the summer of 1988. Thirteen species of fish and five species of…
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…
Re-evaluation of geographic variation in the white flank patch of dalli-type Dall’s porpoises
Amano, Masao; Marui, Miho; Guenther, Tamara; Ohizumi, Hiroshi; Miyazaki, Nobuyuki
Marine Mammal Sci (2000)
(...) 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…
Evolution, taxonomy and antitropical distributions of the porpoises (Phocoenidae, Mammalia)
Barnes, Lawrence G.
Marine Mammal Sci (1985)
True porpoises are a morphologically distinctive and evolutionarily old group of odontocete cetaceans classified as the family Phocoenidae. They are distinct from members of the family Delphinidae, with which they…
Segregative migration of Dall’s porpoise (Phocoenoides dalli) in the Sea of Japan and Sea of Okhotsk
Amano, Masao; Kuramochi, Toshiaki
Marine Mammal Sci (1992)
Dall's porpoises from the Sea of Japan population taken by a dolphin fishery vessel were examined. Estimated body lengths at sexual maturity were similar to those for the truei-type population…
First record of a truei-type Dall’s porpoise from the eastern north Pacific
Szczepaniak, Isidore D.; Webber, Marc A.; Jefferson, Thomas A.
Marine Mammal Sci (1992)
(...) On 28 August 1989, we were informed by California State Park Ranger Robert Breen that a small porpoise had washed ashore at the James Fitzgerald Marine Reserve, San Mateo…
Swimming behaviors and speeds of wild Dall’s porpoises (Phocoenoides dalli)
Law, T. C.; Blake, R. W.
Marine Mammal Sci (1994)
(...) Several researchers have obtained accurate speed data on unconfined cetaceans using a variety of techniques. Hui (1989) analyzed video tapes of Delphinus delphis and Stenella attenuata filmed from a…
Geographic variation in external morphology of Dall’s porpoise, Phocoenoides dalli
Amano, M.; Miyazaki, N.
Aquatic Mammals (1996)
We examined geographic variation in external measurements of Dall’s porpoises, using 269 sexually mature specimens from throughout their range, excluding coastal waters off North America and the northern Okhotsk Sea.…
Observations on the distribution and behavior of Dall’s porpoise (Phocoenoides dalli) in Monterey Bay, California
Jefferson, T.
Aquatic Mammals (1991)
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…
