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…
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…
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…
An interaction between Pacific white-sided dolphins and a neonatal harbor porpoise
Baird, R. W.
Mammalia (1998)
(...) Inter-specific behavioral interactions in the order Cetacea are diverse and often complex, including predation (e.g. Jefferson el al. 1991), "harassment" (Shane 1995 ; Shelden et al. 1995; Palacios and…
Violent interactions between bottlenose dolphins and harbour porpoises
Ross, H. M.; Wilson, B.
Proceedings of the Royal Society B: Biological Sciences (1996)
The majority (63%) of harbour porpoises stranded around the Moray Firth, Scotland, died from trauma characterized by multiple skeletal fractures and damaged internal organs. Surface injuries consisted of skin cuts…

Surface and dive times of finless porpoises in Hong Kong’s coastal waters
Beasley, I.; Jefferson, T. A.;
The Raffles Bulletin of Zoology (2002)
We studied the surface and dive times of finless porpoises (Neophocaena phocaenoides) in Hong Kong from three land-based survey sites in winter/spring 2000, to allow the estimation of the trackline…
