(...) 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.…
Line transect analysis was applied to the 1987-1990 North Pacific marine mammal sightings survey data, with a regression adjustment for size-biased sampling of schools. Abundance of Pacific white-sided dolphins is…
Remotely-deployable non-invasive (suction-cup attached) tags to record underwater behavior of cetaceans have recently been developed. How useful these tags are for applications on a broad range of species has yet…
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…
Published descriptions of the biology of the spectacled porpoise, Australophocaena dioptrica, are reviewed and compared to new material collected in Tierra del Fuego and Chubut, Argentina. Although over 173 cranial…
(...) The original description of the holotype of P. dioptrica was based on an unique and distinctive color pattern. The dorsal surface and upper lateral surface to just above the'…
The world's most endangered marine cetacean, the vaquita (Phocoena sinus), continues to be caught in small-mesh gillnet fisheries throughout much of its range. We monitored fishing effort and incidental vaquita…
Sightings of 37 groups of vaquitas, Phocoena sinus, with an estimated total of 62 individuals, are reported from six major systematic surveys and four small boat surveys in the Gulf…
This paper reviews available information on the population biology and incidental mortality of the vaquita, Phocoena sinus. A re-examination of previous records and the collection of new records reveals that…
