(...) Neophocaena phocaenoides is the only member of the family Phocoenidae without a dorsal fin (Fig. I ). In its place is a low, geographically-variable dorsal ridge (sometimes inappropriately called…
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…
Sexually dimorphic proportions of the harbour porpoise (Phocoena phocoena) skeleton
Galatius, Anders
Journal of Anatomy (2005)
Sexual differences in growth, allometric growth patterns and skeletal proportions were investigated by linear measurements of skeletal parts on 225 harbour porpoises (Phocoena phocoena) from the inner Danish and adjacent…
Bilateral directional asymmetry of the appendicular skeleton of the harbor porpoise (Phocoena phocoena)
Galatius, Anders; Jespersen, Ase
Marine Mammal Sci (2005)
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.…

Doctoral Thesis - Universidade Federal do Rio Grande do Sul (2006)
"Geographic variation of Burmeister's porpoise, Phocoena spinipinnis (Burmeister, 1865) (Cetacea: Phocoenidae), on the Atlantic and Pacific coasts of South America" (Thesis content in English) A total of 142 skulls from…
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…

The ecological and conservation status of the geographically isolated Black Sea harbour porpoise is currently unknown. Although it has been suggested that Black Sea harbour porpoises are distinct from other…
Intermingling of dalli-type Dall’s porpoises into a wintering truei-type population off Japan: Implications from color patterns
Amano, Masao; Hayano, Azusa
Marine Mammal Sci (2007)
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…
