Aquatic Mammals (1989)
The post-mortem findings in 38 stranded harbour porpoises during the period 23rd March 1983 to 25th June 1986 in The Netherlands results in a general view about the parasitological status…
The olfactory regions in the nose of the harbour porpoise Phocoena phocoena (Linnaeus, 1758)
Behrmann, G.
Aquatic Mammals (1989)
(...) 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…
Anatomical and histological characteristics of the eyes of a month-old and an adult harbor porpoise (Phocoena phocoena)
Kastelein, Ronald A.; Zweypfenning, Ruud C. V. J.; Spekreijse, Henk
Sensory Abilities of Cetaceans (1990)
Several anatomical characteristics of the cornea, lens, iris and retina of the eyes of a month-old and an adult harbor porpoise (Phocoena phocoena) were investigated by scanning, transmission and light…
Forehead anatomy of Phocoena phocoena and Cephalorhynchus commersonii: 3-dimensional computer reconstructions with emphasis on the nasal diverticula
Amundin, Mats; Cranford, Ted
Sensory Abilities of Cetaceans (1990)
(...) Watkins et al. (1977) and Dudok van Heel (1981) point to similarity in sound output in Cephalorhynchus and Phocoena, and suggest that it may be the result of convergent…
Studies on echolocation of porpoises taken in salmon gillnet fisheries
Hatakeyama, Yoshimi; Soeda, Hideo
Sensory Abilities of Cetaceans (1990)
(...)In the Bering Sea, marine mammals, particularly Dall's porpoises, Phocoenoides dalli, get incidentally entangled in gillnets of the Japanese mothership salmon fishery. The maximum total number of Dall's porpoises to…
Marginal papillae on the tongue of the Harbour porpoise (Phocoena phocoena), Bottlenose dolphin (Tursiops truncatus) and Commerson’s dolphin (Cephalorhynchus commersonii)
Kastelein, R. A.; Dubbeldam, J. L
Aquatic Mammals (1990)
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…
Best vision zones in the retinae of some cetaceans
Mass, Alla; Supin, Alexander
Sensory Abilities of Cetaceans (1990)
(...) Organization of the visual system in Cetacea still remains unclear in many respects. Of special interest are data on ganglion cell distribution in the retina. It is related closely…
The medical treatment of 3 stranded Harbour porpoises (Phocoena phocoena)
Kastelein, R. A.; Bakker, M. J.; Dokter, T.
Aquatic Mammals (1990)
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…
The tuberous organs of the harbour porpoise Phocoena phocoena (Linné, 1758)
Behrmann, G.
Aquatic Mammals (1990)
(...) 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…
The relationship between body weight and morphological measurements in Harbour porpoises (Phocoena phocoena) from the North Sea
Kastelein, R. A.; van Battum, R.
Aquatic Mammals (1990)
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…
