Aquatic Mammals (2009)
Heterochrony, the change in timing of developmental processes, is thought to be a key process shaping the numerous limb morphologies of tetrapods. Through a delayed offset in digit development, all…

Toothed whales (Odontoceti, Cetacea) are the only aquatic mammals known to echolocate, and probably all of them are able to produce click sounds and to synthesize their echoes into a…
A new species of phocoenid cetacean Haborophocoena, collected from the Early Pliocene Embetsu Formation, in the close vicinity to the site where the holotype of the type species of the…
In several publications, it was shown that echolocation sound generation in the nasal (epicranial) complex of toothed whales (Odontoceti) is pneumatically driven. Modern hypotheses consider the larynx and its surrounding…
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…
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…
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…
Most knowledge on the biology and ecology of the spectacled porpoise (Phocoena dioptrica) has been obtained from stranded specimens, with less than fifteen confirmed sightings in the sea. Published photographs…
"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…
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,…
