(...) Little data exists on the swimming movements of dolphins and whales. The earliest record of cetacean swimming kinematics came from Parry (1949), who observed the swimming motions of a…

Most of the data collected on the reproduction of harbour porpoises (Phocoena phocoena) comes from by-caught or stranded animals and is therefore opportunistic in nature. Harbour porpoises kept in a…
Epidermal thickness and relative papillary height of the skin from the urogenital region were compared with values from the ventral aspect of the flipper and the mid-dorsal body wall. Data…
The refractive index of the cornea of a harbor porpoise eye was measured by two-wavelengths laser-interferometry. In the thickest part of the cornea a refractive index of about 1.53 was…
From length and girth measurements of live stranded animals, treated at the Harderwijk Marine Mammal Park, a formula has been developed to calculate the body weight of Harbour porpoises from…
(...) Tuberous organs in the integument of the harbour porpoise were briefly described for the first time in connection with other nerve end corpuscles in the tongue (Behrmann, 1988). A…
In March 1988 three Harbour porpoises (Phocoena phocoena) were stranded on the Dutch coast and sent to the Harderwijk Marine Mammal Park for rehabilitation. The following parameters were recorded during…
This study shows that in Bottlenose dolphins and in Harbour porpoises the presence of marginal papillae is age related. In Bottlenose dolphins the papillae disappear around the age of 16…
(...) The anatomy of the odontocete brains indicates that they can taste but cannot smell. Apparently, when the blowhole migrated to the top of the head, the neural pathways for…
The heart rates of 3 Harbour porpoises (recorded for 26 days) showed individual variation. Electrocardiograms of two of these animals, made while they were on land, showed respiratory arrhythmia. The…
