Fishery Bulletin (1990)
Examination of 95 Dall's porpoise specimens incidentally caught in gill nets, and 4 collected as beach strandings, indicate significant sexual dimorphism and developmental variation in several aspects of external morphology…
De novo assembly and characterization of narrow-ridged finless porpoise renal transcriptome and identification of candidate genes involved in osmoregulation
Ruan, Rui; Guo, Ai-Huan; Hao, Yu-Jiang; Zheng, Jin-Song; Wang, Ding
International Journal of Molecular Sciences (2015)
During the evolutionary transition from land to water, cetaceans have undergone numerous critical challenges, with osmoregulation being the major one. Two subspecies of the narrow-ridged finless porpoise (Neophocaena asiaeorientalis), the…
Comparative anatomical study on the relationships between the vestigial pelvic bones and the surrounding structures of finless porpoises (Neophocaena phocaenoides)
Tajima, Yuko; Hayashi, Yoshihiro; Yamada, Tadasu K.
Journal of Veterinary Medical Science (2004)
Morphology of the modern cetaceans represents the results of adaptation of the ancestral terrestrial mammals to aquatic life through their evolutional processes. Some of the primitive fossil cetaceans are known…
Protected species bycatch estimating approaches: Estimating harbor porpoise bycatch in U.S. Northwestern Atlantic gillnet fisheries
Orphanides, C. D.
Journal of Northwest Atlantic Fishery Science (2010)
Harbor porpoise bycatch estimates for federally managed gillnet fisheries in northwestern Atlantic US waters were calculated for a nine-year period (1999–2007) using two new methods, and the results were compared…
Trends in the maternal investment of harbour porpoises are uncoupled from the dynamics of their primary prey
Read, A. J.
Proceedings of the Royal Society B: Biological Sciences (2001)
Harbour porpoises in the Bay of Fundy and Gulf of Maine feed primarily on Atlantic herring. Herring stocks have undergone dramatic fluctuations in abundance over the past three decades due…

Veterinary Pathology (2014)
The liver can be an indicator of the health of an individual or of a group, which can be especially important to identify agents that can cause disease in multiple…
Food of the Pacific white-sided dolphin, Lagenorhynchus obliquidens, Dall’s porpoise, Phocoenoides dalli, and northern fur seal, Callorhinus ursinus, off California and Washington; with appendices on size and food of Dall’s porpoise from Alaskan waters
Kajimura, H.; Fiscus, C. H.; Stroud, R. K.
NOAA Technical Memorandum NMFS F/NWC-2 (1980)
The food of the Pacific white-sided dolphin, Lagenorhynchus obliquidens, and Dali's porpoise, Phocoenoides dalli -- collected off California and Washington in 1958-72 -- is compared with food of the northern…
Some observations on the schools of dalli- and truei-type Dall’s porpoises in the northwestern Pacific
Miyazaki, N.; Jones, L. L.; Beach, R.
Scientific Reports of the Whales Research Institute (1984)
During 349 hours of sighting surveys conducted from late June to early August 1979 in the northwestern North Pacific Ocean and the southern Bering Sea, 167 schools of Phocoenoides dalli…
Second record of spectacled porpoise from subantarctic southwest Pacific
Fordyce, R. E.; Mattlin, R. H.; Dixon, J. M.
Scientific Reports of the Whales Research Institute (1984)
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…
Growth of Dall’s porpoise in the western north Pacific and suggested geographical growth differentiation
Kasuya, T.; Shiraga, S.
Scientific Reports of the Whales Research Institute (1985)
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…
