Investigations on Cetacea (1980)
(...) The research shows that the finless porpoise of the Changjiang (Yangtze river) presents an atrophy ofthe entire optic system - eye and eye muscle nerves, optic nerve, optic pathways.…

The Chinese finless porpoise of the Changjiang river, Neophocaena asiaeorientalis (PILLERI and GIHR, 1972) presents a taxonomic entity which differs from N. phocaenoides (G. CUVIER, 1829) of south and south-west…
For the first time in cetaceans, the development of the terminalis system and its continuity between the olfactory placode and the telencephalon has been demonstrated by light microscopy. In the…
Morphogenesis of the brain in a cetacean species has been investigated by means of reconstructions from serial sections of successive prenatal stages of the harbour porpoise (Phocoena phocoena). Four specimens…
The conducting system of the heart of the harbour porpoise (Phocoena phocoena, Linnaeus, 1758) is described macroscopically as well as microscopically. The topography and microscopy of this system in the…
(...) Tongues (Lingua) of dead harbour porpoises are much smaller than those of comparable terrestrial mammals (Boenninghaus, 1903). With the exception of a small area at the tip of the…
(...) 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…
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…
(...) 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 olfactory system of the harbour porpoise is reduced but has a function. The visual system of the harbour porpoise is badly developed, and its inferior to the one of…
