Morphogenesis of the brain in the harbour porpoise

Journal of Comparative Neurology, 1988
AbstractMorphogenesis 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 ranging from 10 to 46 mm crown‐rump length (CRL) were selected and three‐dimensional reconstructions of the developing brains were ...

Status of the harbour porpoise in Greenland

Polar Biology, 1998
In Greenlandic waters the harbour porpoise (Phocoena phocoena) has been observed around the southern part of Greenland from Ammassalik on the east coast to Avanersuaq in northwest Greenland. The main distribution lies between Sisimiut and Paamiut in central west Greenland.

Precocious hearing in harbour porpoise neonates

Journal of Comparative Physiology A, 2017
Hearing is the primary sensory modality for toothed whales, but it is not known at which age it is fully developed. For newborn calves, hearing could fill an important function in maintaining contact with the mother and to develop echolocation skills.

Mycotic Otitis Media in a Harbour Porpoise (Phocoena phocoena)

Journal of Comparative Pathology, 2010
A 9-year-old by-caught harbour porpoise (Phocoena phocoena) was subject to routine post-mortem examination. Major findings included parasitic infection (Stenurus minor) of the left middle ear and severe mycotic infection of the right middle ear. The morphological appearance of the causative organism was consistent with Aspergillus fumigatus.

Mass mortality in harbour seals and harbour porpoises caused by an unknown pathogen

Veterinary Record, 2008
EPIDEMICS caused by phocine distemper virus (pdv) resulted in mass mortalities of European harbour seals ( Phoca vitulina ) in 1988 and 2002 ([Harkonen and others 2006][1]). A third epidemic started in June 2007; the gross pathological changes observed in seals that died in the 2007 outbreak ...

Group hunting in harbour porpoises (Phocoena phocoena)

Canadian Journal of Zoology, 2021
Cooperative hunting involves individual predators relating in time and space to each other’s actions to more efficiently track down and catch prey. The evolution of advanced cognitive abilities and sociality in animals are strongly associated with cooperative hunting abilities as has been shown in lions, chimpanzees, and dolphins.

CLICK COMMUNICATION IN HARBOUR PORPOISESPHOCOENA PHOCOENA

Bioacoustics, 2011
ABSTRACT 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 frequency (NBHF) clicks, such as the harbour porpoise Phocoena phocoena.

Organochlorine residues in harbour porpoises from Southwest Greenland

Environmental Pollution, 2004
During the 1995 hunting season, 75 harbour porpoises (Phocoena phocoena) were sampled in three locations in West Greenland: Maniitsoq, Nuuk, and Paamiut. Sex, age, morphometrics, reproductive condition, and organochlorine compound (OC) levels in blubber were determined for each individual. OC levels were extremely low and, therefore considered unlikely

Prey capture by harbour 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 2007.
