Investigations on Cetacea (1969)
Among captive harbour porpoises, Phocaena phocaena (L.) epimeletic behaviour has been observed. Nurturant behaviour was performed by a juvenile female and a juvenile male toward sucklings and evidence is given…
Fatty acid composition of finles porpoise oil
Tsuyuki, H.; Itoh, S.
Scientific Reports of the Whales Research Institute (1969)
1) The properties of Finles porpoise oil were studied. 2) Fatty acid composition of Finles porpoise oil was analyzed by gas-liquid chromatograph using a hydrogen ionization detector on a DEGS…
Brain-spinal cord ratios in porpoises: Possible correlations with intelligence and ecology
Ridgway, S. H.; Flanigan, N. J.; McCormick, J. G.
Psychonomic Science (1966)
As a rough measure of intelligence, brain weight: cord weight ratios in small delphinids compared favorably with, but were slightly less than , this ratio in man. Not all delphinids…

(...) Flower (1883), in his search for the trenchant characters he needed to reach a decision about the arrangement of the Delphinidae, saw that the configuration of the pterygoid bones…
Blood oxygen and ecology of porpoises of three genera
Ridgway, S.H.; Johnston, D.G.
Science (1966)
Blood volumes, hemoglobin concentrations, packed-cell volumes, and heart weights were determined in three genera of porpoises which differ from one another in behavior and ecology. The estimate for the total…
A discussion of rarities among the smaller cetaceans caught in Japanese waters
Nishiwaki, M.
Whales, Dolphins, and Porpoises [Proceedings] (1966)
There are many species of cetaceans in the waters around Japan. Some are migratory, but others seem to be permanent residents. The rarities among the small cetaceans caught by Japanese…
