Hiatal Hernia in a Harbor Porpoise (Phocoena phocoena)
Journal of Wildlife Diseases, 1993We observed the displacement of the first compartment of the stomach through the diaphragmatic hiatus into the thoracic cavity in an immature harbor porpoise (Phocoena phocoena). This hiatal hernia, coupled with a severe pneumonia, contributed to the emaciation and death of the animal.

Click Structure in the Porpoise, Phocoena phocoena
Journal of Mammalogy, 1969The phonation of Phocoena phocoena consists of low intensity, narrow-band clicks usually near 2 kilohertz, produced singly or in bursts at repetition-rates as great as about 1000 per second. the higher repetition-rates show as harmonic bands in spectral analysis when relatively narrow analyzing filters are used. Many clicks contain variable emphasis at

Trace metals in the common porpoise, Phocoena phocoena
Marine Environmental Research, 1983Mercury, cadmium, copper and zinc concentrations in brain, liver, kidney, heart and spleen of twenty-six specimens of the common porpoise (Phocoena phocoena) are presented. Mercury and cadmium levels in liver and kidneys tended to increase with length of animal, but copper and zinc levels show no such trends.

The stomach of the harbor porpoise Phocoena phocoena (L.)
Canadian Journal of Zoology, 1972The morphological and cytological characteristics of the stomach of the harbor porpoise (Phocoena phocoena (L.)) are described from dissections and histological preparations. The stomach consists of the following three compartments: forestomach, with keratinized stratified squamous epithelium and well-developed muscularis externa; main stomach, with ...

Based on air-shooting and observation from the vessels (1970???90s), the distribution maps of harbour porpoise, ??hocoena phocoena relicta Abel, 1905 in the Black Sea during the spring-autumn period are provided and described. The opinion about the exclusively coastal distribution is refuted and their occurrence in the open waters is shown. The harbour
