(...) Order Cetacea, Suborder Odontoceti, Family Phocoenidae. The family contains four extant genera: Phocoena, Australophocaena, Neophocaena, and Phocoenoides (Barnes, 1985). Barnes (1984, 1985) has proposed two subfamilies within the Phocoenidae.…
The behavior of Dall's porpoise was studied in the western Johnstone Strait, British Columbia, during the summer of 1984. Observations and theodolite trackings were made from a cliff-top observation point…
Eighty nine mother-calf Dall's porpoise pairs were sighted in August and September 1982, 1983 and 1985 in the Bering Sea and the western North Pacific (outside the principal range of…
Genetic variability and differentiation of three families containing 12 species of toothed whales mainly from the sea around Japan have been examined by starch-gel electrophoresis at 19 genetic loci encoding…
(...) Makino (1948) studied chromosomes of a male P. dalli using traditional sectioning of testis tissue. Since it was generally accepted in those days that the two color morphs represent…
(...) This document attempts to gather together as much information as is available on the extent of current killings of small cetaceans throughout the world, and also to highlight some…
Some growth parameters of the western North Pacific dalli-type Dall's porpoise were estimated from 167 specimens taken with hand-held harpoons on two cruises and compared with data obtained previously from…
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…
(...) Although various sensory mechanisms are present in cetaceans, special navigational problems occur when animals are in a pelagic environment which can minimize available cues. Dawbin (1966) has observed that…
To improve knowledge of the life history of Dall's porpoise, Phocoenoides dalli (True, 1885) that are incidentally caught by the Japanese salmon mothership fishery in the northwestern North Pacific, a…
