Some growth parameters of the western North Pacific dalli-type Dall's porpoise were estimated from 167 specimens taken with hand-held harpoons on two cruises and compared with data obtained previously from…
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…
This paper reviews the current state of knowledge of the food habits of the poorly known small cetaceans of the Southern Ocean and presents new information obtained through a study…
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…
(...) Although various sensory mechanisms are present in cetaceans, special navigational problems occur when animals are in a pelagic environment which can minimize available cues. Dawbin (1966) has observed that…
An incomplete skull of unknown sex of a sub-adult spectacled porpoise (Phocoena dioptrica Lahille, 1912) was collected at Macquarie Island (54°30'S, 159°00'E) in July 1957. Cranial measurements are given, and…
The population biology of most phocoenid species is still rather poorly understood. It is important that we improve our knowledge in view of concerns which have been expressed in recent…
The purpose of this study was to gather base-line life history data on the harbor porpoise. The information presented here describes only those aspects which would affect a census. During…
The distribution of the harbour porpoise Phocoena phocoena (L.). is re-examined using a compilation of all available recent information. Three isolated major populations of this species exist: in the North…
