Highly significant (α = 0.01) differences in analysis of 473 skulls of harbour porpoises indicate separate eastern Pacific, western Atlantic, and eastern Atlantic populations. Including the isolated population in the…

The vaquita, Phocoena sinus, is a porpoise in the family Phocoenidae that lives only in the Gulf of California. The external appearance of P. sinus was unknown until 13 fresh…
(...) Order Cetacea, Suborder Odontoceti, Family Phocoenidae. The family contains four extant genera: Phocoena, Australophocaena, Neophocaena, and Phocoenoides (Barnes, 1985). Barnes (1984, 1985) has proposed two subfamilies within the Phocoenidae.…
(...) The free-swinging bullae of odontocetes are very massive, their specific weight being twice that of the other skull bones. This feature led Yamada (1953) to his theory that the…
Examination of 95 Dall's porpoise specimens incidentally caught in gillnets, and four collected as beach strandings, indicate that there is significant sexual dimorphism and developmental variation in several aspects of…
(...) Guiler, Burton and Gales (1987) reported a cranium (Tasmanian Museum No. A1411) they identified as belonging to Burmeister’s porpoise, Phocoena spinipinnis (Burmeister, 1865) from Heard Island (53°S 73°30’E). They…

Two hundred and eighty-nine skulls of Dall's porpoises from the North Pacific Ocean, Sea of Japan, Sea of Okhotsk, and Bering Sea were investigated morphometrically. A clear pattern of geographic…
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…
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…
