"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…
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…
Tooth ultrastructure in harbour porpoise is examined as a possible tool for differentiating between animals from different geographical regions in the North Atlantic. Nine different characteristics in both dentine and…
There are many species of cetaceans in the waters around Japan. Some are migratory, but others seem to be permanent residents. The rarities among the small cetaceans caught by Japanese…

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…
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…
The unique pattern of small tubercles on the leading edge of the dorsal fins of harbor porpoises (Phocoena phocoena) has been widely noted in the literature, though their structure or…
Modern porpoises (Odontoceti: Phocoenidae) are some of the smallest cetaceans and usually feed near the seafloor on small fish and cephalopods [1, 2 and 3]. Within both extinct and extant…
