To evaluate and quantify sexual dimorphism of skull shape and assess the ontogenetic background for differences, samples of 134 harbor porpoise (Phocoena phocoena) and 85 Dall's porpoise (Phocoenoides dalli) were…
(...) I am enabled to add a new species, through the kindness of Mr. William H. Dall, who has placed at my disposal his notes upon and drawings of two…
The harbor porpoise, and other toothed whales, use a biosonar click sequence that resembles the sequence of cries used by insectivorous bats when hunting for and capturing prey. The temporal…
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…
We compared the distribution of the digenean Pholeter gastrophilus in the stomach of 27 harbour porpoises, Phocoena phocoena, 27 striped dolphins, Stenella coeruleoalba, 18 bottlenose dolphins, Tursiops truncatus, and 100…
Small cetacean bycatch in gillnet fisheries may be reduced by deterring odontocetes from nets acoustically. However, different odontocete species may respond differently to acoustic signals from alarms. Therefore, in this…
Structural modifications of the odontocete skull and nasal passages have shifted the position of the facial bones and associated soft anatomy to the dorsal aspect of the head. The facial…
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…
Previous double team experiments testing line transect methodology for harbor porpoise indicated that a relatively small proportion of the sightings were actually seen by both teams. Results of an additional…
(...) Brody (1945) fitted an allometric equation to heart mass (kg) as a function of body mass (kg) for adult mammals ranging in body size from 0.01 to over 100,000…
