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…

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…
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…
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…
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…
The skull and incomplete skeleton of a specimen of Phocoena sinus from the Gulf of California are described and compared with specimens of P. phocoena and P. spinipinnis. The skeleton…
The seasonal and annual fluctuation of the sperm whale, Baird's beaked whale, killer whale, the globicephalids, and the dolphins and porpoises in the past 11 years are discussed. The sperm…
In spite of important differences in shape and appearance, the tongues of Pontoporia blainvillei, Neomeris phocaenoides and Delphinus tropicalis present certain common characteristics. None have papillae resembling, even slightly, those…
Information is communicated on the occurrence of Phoconea spinipinnis off the Uruguayan coast and on the general geographical distribution of this rare species. In contradiction to the observations of ALLEN…
This paper is a contribution to the knowledge of the marine and estuarine cetacean fauna of Pakistani waters and it is based on the investigation of our own material collected…
