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.

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.

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

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 ...
