This study shows that in Bottlenose dolphins and in Harbour porpoises the presence of marginal papillae is age related. In Bottlenose dolphins the papillae disappear around the age of 16…

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…
Morphogenesis of the brain in a cetacean species has been investigated by means of reconstructions from serial sections of successive prenatal stages of the harbour porpoise (Phocoena phocoena). Four specimens…
-San Antonio, Texas- In July of 1987, a Dall's porpoise (Phocoenoides dalli), with her umbilical cord still attached, stranded in Bodega Bay, California. She was transported to Marine World Africa,…
For the first time in cetaceans, the development of the terminalis system and its continuity between the olfactory placode and the telencephalon has been demonstrated by light microscopy. In the…
The early postnatal growth of bottlenose dolphins and finless porpoises was studied using 97 body length records of 61 individuals born in aquariums. The growth rates observed were similar to…
The vaquita (Phocoena sinus) is a small porpoise found only in the northern Gulf of California. This species may have been subject to high levels of mortality in the gill-net…
Some growth parameters of the western North Pacific dalli-type Dall's porpoise were estimated from 167 specimens taken with hand-held harpoons on two cruises and compared with data obtained previously from…
Serial sections of 13 embryos and fetuses of the harbor porpoise from 10 mm crown-rump length up to 167 mm total length were studied. Unlike the adult animals, ontogenetic stages…
To improve knowledge of the life history of Dall's porpoise, Phocoenoides dalli (True, 1885) that are incidentally caught by the Japanese salmon mothership fishery in the northwestern North Pacific, a…
