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…
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…
Highly significant (α = 0.01) differences in analysis of 473 skulls of harbour porpoises indicate separate eastern Pacific, western Atlantic, and eastern Atlantic populations. Including the isolated population in 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…
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…
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…
