A total of 56 vaquitas (Phocoena sinus) were examined to evaluate their sexual dimorphism and isometric and/or allometric growth in 35 external characteristics. Absolute and relative (to total length) measurements…
There are two major color morphs, truei and dalli types, of the Dall's porpoise and the latter includes two minor morphs. A small number of dalli types are found among…
Directional asymmetry (DA) of the lengths, diameters, and masses of the scapula, humerus, radius, and ulna were analyzed on a sample of 213 harbor porpoises from Denmark and West Greenland.…
A total of 433 skulls of harbor porpoises, Phocoena phocoena, were examined to evaluate geographical variation within the western North Atlantic, using analysis of covariance and discriminant analysis based on…
(...) Burmeister's porpoise inhabits temperate waters of South America, from Tierra del Fuego to Rio de la Plata (Uruguay) on the Atlantic coast, and from Tierra del Fuego to Paita…
(...) Amano and Miyazaki (1996) found a geographic difference in the size of the white flank patch among dalli-type animals and reported that porpoises from the Sea of Japan-Okhotsk population…
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…
(...) 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…
Development, sexual dimorphism, and individual variation were examined in the skeleton of the finless porpoise in the coastal waters of western Kyushu, Japan. Skulls ceased growing by 4 yr. Postcranial…
