Marine Pollution Bulletin (1997)
A wide range of organochlorine residues were determined in the blubber of harbour porpoises from the Black Sea. Concentrations of DDTs (8.3–180 μg g−1 wet weight) were the highest followed…

This report provides harbor porpoise bycatch estimates for 1994 and 1995. The analysis required adjusting for changes in data collection methods that went into effect in June 1994, in which…
Target discrimination by an echolocating finless porpoise, Neophocaena phocaenoides
Nakahara, Fumio; Takemura, Akira; Koido, Takashi; Hiruda, Hisoka
Marine Mammal Sci (1997)
The ability of a finless porpoise (Neophocaena phocaenoides) to discriminate the material and size of a target by echolocation was investigated. The porpoise was required to choose a standard target…
The behaviour of Hong Kong’s resident cetaceans: The Indo-Pacific humpbacked dolphin and the finless porpoise
Parsons, E. C. M.
Aquatic Mammals (1998)
A series of behavioural surveys were conducted in Hong Kong upon resident populations of Indo-Pacific hump-backed dolphins (Sousa chinensis) and finless porpoises (Neophocaena phocaenoides). The surveys were carried out from…

Otani, Seiji; Naito, Yasuhiko; Kawamura, Akito; Kawasaki, Masahiro; Nishiwaki, Shigetoshi; Kato, Akiko
Marine Mammal Sci (1998)
In order to monitor the diving behavior of free-ranging cetaceans, microdataloggers, with pre-programmed release mechanisms, were attached to the dorsal fins of two female harbor porpoises (Phocoena phocoena) in Funka…
Seasonal patterns in the abundance and distribution of California cetaceans, 1991-1992
Forney, Karin A.; Barlow, Jay
Marine Mammal Sci (1998)
This study presents a detailed seasonal comparison of the abundance and distribution of cetaceans within 100-150 nmi (185-278 km) of the California coast during 1991 and 1992. The results of…
Family Phocoenidae Gray, 1825
Rice, D.W.
Marine Mammals of the World: Systematics and Distribution (1998)
(page 121) (...) Miller (1925) and Kellogg (1928) included the true porpoises in the family Delphinidae and did not even grant them subfamily status. However, Slijper (1936) and Fraser and…

Canadian Journal of Zoology (1998)
A 60-cm female fetus recovered from a Dall's porpoise (Phocoenoides dalli) found dead in southern British Columbia was fathered by a harbour porpoise (Phocoena phocoena). This is the first report…
An interaction between Pacific white-sided dolphins and a neonatal harbor porpoise
Baird, R. W.
Mammalia (1998)
(...) Inter-specific behavioral interactions in the order Cetacea are diverse and often complex, including predation (e.g. Jefferson el al. 1991), "harassment" (Shane 1995 ; Shelden et al. 1995; Palacios and…
Evidence for infanticide in bottlenose dolphins: an explanation for violent interactions with harbour porpoises?
Patterson, I. A. P.; Reid, R. J.; Wilson, B.; Grellier, K.; Ross, H. M.; Thompson, P. M.
Proceedings of the Royal Society B: Biological Sciences (1998)
Most harbour porpoises found dead on the north–east coast of Scotland show signs of attack by sympatric bottlenose dolphins, but the reason(s) for these violent interactions remains unclear. Post–mortem examinations…
