(...) Order Cetacea, Suborder Odontoceti, Family Phocoenidae. The family contains four extant genera: Phocoena, Australophocaena, Neophocaena, and Phocoenoides (Barnes, 1985). Barnes (1984, 1985) has proposed two subfamilies within the Phocoenidae.…
Bioacoustics (2010)
Sound plays an important role for toothed whales in foraging and communication. However, little is known about acoustic communication in the toothed whale species that only produce narrow band high…

Burmeister's porpoise (Phocoena spinipinnis), one of the most common small cetaceans in Peruvian waters, suffers the second highest fishing mortality. Biological data obtained from porpoises caught in gillnets off Peru…
Journal of Cetacean Research and Management (2006)
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…

Most harbour porpoises found dead on the north–east coast of Scotland show signs of attack by sympatric bottlenose dolphins, but the reason(s) for these violent interactions remains unclear. Post–mortem examinations…
Doctoral Thesis - University of British Columbia (2011)
Behavioural observations are fundamental to understanding and defining the habitat needs of animals. I compiled the behavioural repertoires reported for harbour (Phocoena phocoena) and Dall’s porpoise (Phocoenoides dalli) by classifying…
Zoological Research (2010)
Underwater behavioral patterns of one Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) calf in captivity and those performed on the water surface by two calves in semi-natural environment were focally followed…
Ethology (2007)
Mate guarding, whereby a male closely attends and defends a fertile female from extra-pair matings, is one mating tactic males of many species use to protect their paternity. Although female…
Behavior of Marine Animals (1979)
Dall’s porpoise, Phocoenoides dalli (True), is commonly encountered over the continental shelf of North America and in offshore and pelagic waters of the western and eastern North Pacific Ocean. This…

The diving behaviour of seven free-ranging harbour porpoises (Phocoena phocoena) was examined using time–depth recorders. In total, 8167 individual dives were recorded over 254 h. The longest period of data collection…
