Notes on a Specimen of the Harbor Porpoise

Journal of Mammalogy, 1957
On May 20, 1955, a small whale was washed ashore at Stillwater Cove, Pebble Beach, Monterey County, California (36°34′N, 121°56′W). Thomas N. Fast, Dr. Elliot C. Williams, and Eric Barham from the Hopkins Marine Station of Stanford University secured the animal while it was still alive and brought it back to the laboratory where it was identified as a ...

Impacts of Anthropogenic Sounds on Phocoena phocoena (Harbor Porpoise)

2012
Anthropogenic underwater sound in the seas and oceans is increasing. Phocoena phocoena (harbor porpoise) is sensitive to underwater sound because of its very acute hearing, wide hearing frequency range, and high responsiveness to sounds. The detection of sounds by animals and the degree to which sounds have an effect on animals involve the ...

The stomach of the harbor porpoise Phocoena phocoena (L.)

Canadian Journal of Zoology, 1972
The morphological and cytological characteristics of the stomach of the harbor porpoise (Phocoena phocoena (L.)) are described from dissections and histological preparations. The stomach consists of the following three compartments: forestomach, with keratinized stratified squamous epithelium and well-developed muscularis externa; main stomach, with ...

Behavioral Reactions of Harbor Porpoise to Pile-Driving Noise

2012
Pile driving of large steel monopiles in offshore waters has increased rapidly in recent years due to the expanding development of offshore wind energy. In particular, Phocoena phocoena (harbor porpoise) has been the focus of attention with respect to a possible negative impact.

Harbor Porpoises and Gill Nets in the Gulf of Maine

Conservation Biology, 1993
In many areas of their range, harbor porpoise (Phocoenaphocoena) populations are either depleted or in decline; incidental catches in commercial fisheries are often implicated as a factor in these declines (Gaskin 1984). Harbor porpoises have disappeared from parts of the Baltic Sea, the southern North Sea, and portions of the central California coast (

Wing design and morphology of the harbor porpoise dorsal fin

Journal of Morphology, 2003
AbstractThe correlation between skin structure and hydrodynamic design of the dorsal fin of the harbor porpoise (Phocoena phocoena) was examined. For the study of fin morphology and geometry, a scheme of sampling representing a two‐parameter mesh on the fin surface was used.

Is there a distinct harbor porpoise subpopulation in the Marmara Sea?

Mitochondrial DNA Part A, 2016
Genetic population structure of geographically isolated endangered Black Sea harbor porpoise (Phocoena phocoena relicta) is little known in Turkish waters, especially in the Turkish Straits System (TSS- Marmara Sea, Bosphorus and Dardanelles), which connects the Black Sea and the Aegean Sea.

Prey capture by harbor porpoises

2009
  The harbor porpoise (Phocoena phocoena) is a small toothed whale living mostly in coastal waters.  There are large, but unknown, numbers in the inner Danish waters. Four are in captivity at Fjord & Bælt, Kerteminde, Denmark, one of which was born here in 2006.

Comparative temporary threshold shifts in a harbor porpoise and harbor seal, and severe shift in a seal

The Journal of the Acoustical Society of America, 2013
Anthropogenic noise may cause temporary hearing threshold shifts (TTSs) in marine mammals. Tests with identical methods show that harbor porpoises are more susceptible to TTS induced by octave-band white noise (OBN) centered around 4 kHz than harbor seals, although their unmasked (basic) hearing thresholds for that frequency are similar.
