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…

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…
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 comprises sight records for nine species and morphometries, color descriptions, and miscellaneous notes on the food and parasites of seven species of small odontocetes observed from West Greenland…
Besides the already known low‐frequency components of the Phocoena echolocation pulse, a narrow‐band pulse of 0.1‐msec duration, with the main energy between 110 and 150 kHz and a source level…
This study confirms earlier observations of apparently involuntary movements, strongly associated with the breathing. The movements include taxes - a dorsal flexure of the thorax and steering movements with the…

A pilot study has been carried out in order to obtain information on the observational problems encountered in studying the harbour porpoise (Phocoena phocoena) in the wild. It is concluded…
The rearing of unweaned dolphins has hitherto not been described in literature. In 1973 our laboratory received 2 juvenile harbour porpoises (Phocoena phocoena) and we succeeded in rearing them on…
The harbour porpoise and all other cetaceans are totally protected in Danish waters, but not in the waters around Greenland and the Faroe Islands. This means that it is forbidden…
