Investigations on Cetacea (1970)
The forced choice variation of the method of constant stimuli was used to study the ability of angular discrimination at 2 kHz of a harbour porpoise Phocoena phocoena. A minimum…
Auditory sensitivity of the harbour porpoise Phocoena phocoena
Andersen, S.
Investigations on Cetacea (1970)
An audiogram has been obtained from the harbour porpoise, Ph.phocoena, in water from 1 to 150 kHz by using the operant conditioning technique. The highest sensitivity was measured between 8…
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…
Electrocardiography of the harbour porpoise, Phocaena phocaena
Andersen, S.
Investigations on Cetacea (1969)
Electrocardiographical examinations have been performed on 4 harbour porpoises, Phocaena phocaena (L.) kept in captivity for studies on their hearing capability. Parameters of the ECG are presented and studies are…
Epimeletic behaviour in captive harbour porpoise, Phocaena phocaena (L.)
Andersen, S.
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…

Ridgway, S.H.
Norsk Hvalfangst-Tidende (1966)
The Dall porpoise Phocoenoides dalli is common in south central California waters from October through June. During the summer months it is not commonly found farther south than about 35°.…

Comments on the Delphinoidea
Fraser, F. C.
Whales, Dolphins, and Porpoises [Proceedings] (1966)
(...) 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…
