Investigations on Cetacea (1979)
Finless porpoise mothers are able to carry their calves balanced securely on their back. This behaviour was frequently observed by the authors in the course of an expedition to the…
Observations on the baiji (Lipotes vexillifer) and the finless porpoise (Neophocaena asiaeorientalis) in the Changjiang (Yangtze) River between Nanjing and Taiyangzhou, with remarks on some physiological adaptations of the baiji to its environment
Zhou, K.; Pilleri, G.; Li, Y.
Investigations on Cetacea (1979)
Two species of dolphin inhabit the Changjiang (Yangtze): Lipotes vexillifer MILLER, 1918 (known as Baiji in Chinese) and the Finless porpoise, Neophocaena asiaeorientalis PILLERI and GIHR, 1972. Although quite a…
Regression of the optic system in the Changjiang (Yangtze) finless porpoise (Neophoceana asiaeorientalis) as a result of lack of light
Chen, P.; Shao, Z.; Pilleri, G.
Investigations on Cetacea (1980)
(...) The research shows that the finless porpoise of the Changjiang (Yangtze river) presents an atrophy ofthe entire optic system - eye and eye muscle nerves, optic nerve, optic pathways.…
Status of the cochito, Phocoena sinus, in the Gulf of California
Brownell, R. L. Jr.
FAO Fisheries Series (1982)
The cochito (Phocoena sinus), the smallest member of its genus, is known from 21 confirmed records from the upper Gulf of California and is probably found only in that area.…
Evolution, taxonomy and antitropical distributions of the porpoises (Phocoenidae, Mammalia)
Barnes, Lawrence G.
Marine Mammal Sci (1985)
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…

Molecular analyses of the truei and dalli morphotypes of Dall’s porpoise (Phocoenoides dalli)
Escorza-Treviño, S.; Pastene, L. A.; Dizon, A. E.
Journal of Mammalogy (2004)
The taxonomic status of the 2 morphologically distinct forms of Dall's porpoises, Phocoenoides dalli (dalli- and truei-type) remains unresolved. To address this uncertainty, mitochondrial DNA (mtDNA) sequences were used to…
Haborophocoena toyoshimai, a new early Pliocene porpoise (Cetacea; Phocoenidae) from Hokkaido, Japan
Ichishima, H.; Kimura, M.
Journal of Vertebrate Paleontology (2005)
Haborophocoena toyoshimai (family Phocoenidae), from the early Pliocene Mochikubetsu Formation in northwestern Hokkaido, Japan, is a new genus and species of porpoise. The holotype is an incomplete skull, tympanoperiotic, mandible,…
The phylogenetic relationships and biogeography of true porpoises (Mammalia: Phocoenidae) based on morphological data
Fajardo-Mellor, Liliana; Berta, Annalisa; Brownell, Robert L.; Boy, Claudia C.; Goodall, R. Natalie P.
Marine Mammal Sci (2006)
Prior studies of phylogenetic relationships among phocoenids based on morphology and molecular sequence data conflict and yield unresolved relationships among species. This study evaluates a comprehensive set of cranial, postcranial,…
Timing of epiphyseal development in the flipper skeleton of the harbour porpoise (Phocoena phocoena) as an indicator of paedomorphosis
Galatius, Anders; Andersen, Mai-Britt Elin Rindom; Haugan, Birgitte; Langhoff, Heidi Elisabeth; Jespersen, Åse
Acta Zoologica (2006)
Epiphyseal development was investigated on X-rays of flippers from 158 harbour porpoises from Danish waters. Development followed a proximodistal pattern similar to what is known in other cetacean species. Ossification…
