The early postnatal growth of bottlenose dolphins and finless porpoises was studied using 97 body length records of 61 individuals born in aquariums. The growth rates observed were similar to…
Of the 79 recent species of cetaceans 51 have been examined relative to the osteology of the flipper and the scapula and, in addition to this, video-recordings of 13 different…
A Harbour Porpoise, Phocoena phocoena, taken from near Shallow Bay, Mackenzie River Delta, Northwest Territories (68°48’ N 136°35’ W) in July 1973 represents a range extension 800 km eastwards from…
(...) Skeletons of two Alaskan porpoises, Phocoena phocoena (Linnaeus) and Phocoenoides dalli (True), have recently been mounted in the United States National Museum. Before these skeletons were placed on exhibition…
The most serious threat to the status of harbour porpoise (Phocoena phocoena) is incidental mortalities caused by entanglement in fishing gear. As part of an ongoing study to evaluate the…

Documented sightings of harbour porpoises in the Mediterranean are rare, although the species is common in the neighbouring North Atlantic and Black Sea. However, in the past 2 decades, 4…
Airguns used in seismic surveys are among the most prevalent and powerful anthropogenic noise sources in marine habitats. They are designed to produce most energy below 100 Hz, but the…
Levels of organochlorine compounds (PCDD, PCDF, PCB and organochlorine pesticides) were determined in cetaceans collected from the west coast of North America between 1986 and 1989. The samples included gray…
Bioaccumulation of immunosuppressive organochlorines like polychlorinated biphenyls (PCBs) may pose a threat to the health and viability of cetacean populations. To investigate possible associations between chronic exposure to PCBs and…
