Variability of the mitochondrial control region in populations of the harbour porpoise, Phocoena
, on interoceanic and regional scales.
is a coastal species preferring shallow waters close to the shore.

in northwestern Europe.
Age, length and reproductive parameters of harbour porpoises Phocoena phocoena
A review of 1990-97 set gillnet fisheries in the Monterey Bay area and revised estimates of mortality for harbor porpoise, Phocoena phocoena
, and sea otters, Enhydra lutris.
Alternately referred to as Phocoena
vomerina in the literature (2), this synonym is no longer accepted (Perrin) (3).

External morphology and pigmentation of the vaquita, Phocoena
sinus (Cetacea, Mammalia).
Rather than a commercial and recreational fishery for the bycatch species, Hoagland and Jin (1997) developed a dynamic model for a nonconsumptive, passive use bycatch species as might be expected for a protected or endangered species; their example species was the harbor porpoise, Phocoena phocoena
, or dolphin.
The thirteen sightings included Pacific white-sided dolphins; Dall's porpoise; killer whales; Risso's dolphins, Grampus griseus; northern right whale dolphins, Lissodelphis borealis; and harbor porpoise, Phocoena phocoena
Take reduction plans currently are in effect for the harbor porpoise, Phocoena phocoena
, in the Mid Atlantic and Gulf of Maine regions; large whales (Eubalaena glacialis, Megaptera novaenangliae, and Balaenoptera physalis) in the Atlantic; and the pilot whale, Globicephala macrorhynchus; pygmy sperm whale, Kogia breviceps; sperm whale, Physeter macrocephalus; humpback whale, Megaptera novaeanliae; and beaked whales (Berardius bairdii, Mesoplodon spp.
The paucity of beluga sightings here was not simply an issue of poor visibility, because other marine mammals, such as sea otters, Enhydra lutris; harbor seals, Phoca vitulina; Steller sea lions, Eumetopias jubatus; and harbor porpoise, Phocoena phocoena
, were seen in abundance in the lower inlet.
Pontoporia blainvillei, Cephalorhynchus hectori, Cephalorhynchus commerssoni, Phocoena phocoena
sinus) are the smallest species within the group.
