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…
Directional hearing in the harbour porpoise Phocoena phocoena
Andersen, S.
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…

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…
