Investigations on Cetacea (1993)
The olfactory system of the harbour porpoise is reduced but has a function. The visual system of the harbour porpoise is badly developed, and its inferior to the one of…

We studied development and sexual dimorphism in external measurements of Dall's porpoises (Phocoenoides dalli) from the northwestern North Pacific. Relative rates of increase in the measurements of the head and…
In 1988 and 1989, thousands of harbor seals (Phoca vitulina) died in the North Sea from phocine distemper infection. The morphology of thyroid glands from 40 harbor seals found dead…
In 1990, 74 dusky dolphins (Lagenorhynchus obscurus) and 10 Burmeister's porpoises (Phocoena spinipinnis) were examined for the presence of hyperpigmented marks and pinhole lesions on the skin (tattoo lesions) at…
We have 189 specimens available for this work. One-hundred and sixty-seven specimens from the Yangtze, Yellow Sea and South China Sea populations were aged and used in studying the growth…
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…
Since 1987, morbillivirus infections have caused serious disease outbreaks with high mortality among aquatic mammals. Baikal seals (Phoca sibirica) in Siberia were involved in an outbreak caused by a virus…
In response to a request from the IWC Scientific Committee, this paper investigates the disagreement between two sets of Japanese statistics for the Dall's porpoise fishery, with particular reference to…
We compared the contents of 31 stomachs of harbour porpoise calves killed in commercial gill nets in the Bay of Fundy between July and September, 1985–1991, with the stomach contents…
Detailed post mortem examinations were carried out on 41 harbour porpoises (Phocoena phocoena) found dead on the coast of the United Kingdom. The commonest causes of death were entanglement in…
