Since 1978, the annual incidental take of Dall's porpoises by the Japanese salmon land-based and mothership fisheries has been reported to the International North Pacific Fisheries Commission by the Japan…
The distribution, movements, and relative population abundance of harbor porpoises were studied in the Fish Harbour region of New Brunswick, Canada (lat. 44°59'30"-45°01'00"N, long. 66°54'00"-66°57'00"W), from 1970 to 1978. In…
True porpoises are a morphologically distinctive and evolutionarily old group of odontocete cetaceans classified as the family Phocoenidae. They are distinct from members of the family Delphinidae, with which they…
Serial sections of 13 embryos and fetuses of the harbor porpoise from 10 mm crown-rump length up to 167 mm total length were studied. Unlike the adult animals, ontogenetic stages…
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…
The objective of this study was to assemble the components of an energy budget for the harbour porpoise in the western Bay of Fundy, Canada. The annual energetic requirements for…
(...) Spondolytis deformans, a pathological deformation of the vertebral column, has so far been found in 41 cases in 26 recent and extinct cetacean species, among them the harbour porpoise…
(...) Dolphins are well-known for their developed hearing and echolocation systems. However, data on the organization of other sensory systems in these animals are limited. Namely, the organization of the…
(...) This document attempts to gather together as much information as is available on the extent of current killings of small cetaceans throughout the world, and also to highlight some…
Genetic variability and differentiation of three families containing 12 species of toothed whales mainly from the sea around Japan have been examined by starch-gel electrophoresis at 19 genetic loci encoding…
