Bauer, G.B.; Fuller, M.; Perry, A.; Dunn, J.R.; Zoeger, J.
Magnetite Biomineralization and Magnetoreception in Organisms: A New Biomagnetism (1985)
(...) 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…
Chromosome number of two color types of the Dall’s porpoise
Yabu, H.; Ogi, H.
Scientific Reports of the Whales Research Institute (1986)
(...) 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…

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 in the toothed whales
Shimura, E.; Numachi, K.-I.
Scientific Reports of the Whales Research Institute (1987)
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…
Sound production by a neonatal Dall’s porpoise (Phocoenoides dalli)
Bain, David E.
Proceedings of the 16th Annual IMATA Conference (1988)
-San Antonio, Texas- In July of 1987, a Dall's porpoise (Phocoenoides dalli), with her umbilical cord still attached, stranded in Bodega Bay, California. She was transported to Marine World Africa,…
Use of organochlorines as chemical tracers in determining some reproductive parameters in Dalli-type Dall’s porpoise Phocoenoides dalli
Subramanian, AN.; Tanabe, Shinsuke; Tatsukawa, Ryo
Marine Environmental Research (1988)
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…
