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…
(...) 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…
(...) 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…
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…
Persistent organochlorines (PCBs and p,p′-DDE) in the bodies of dalli- and truei-type Dall's porpoises (Phocoenoides dalli) from the Bering Sea and the northwestern North Pacific were used as chemical tracers…
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…
(...) 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.…
