Abstract:
Structural modifications of the odontocete skull and nasal passages have shifted the position of the facial bones and associated soft anatomy to the dorsal aspect of the head. The facial structures of true porpoises, Phocoenidae, are highly specialized. Facial regions of 18 Phocoena phocoena and 3 Phocoenoides dalli specimens were dissected and described. In addition, heads of three phocoenid specimens were serially sectioned. Comparison to delphinid facial anatomy demonstrates that nasal passages, associated diverticula, and facial muscles of these phocoenid species are homologous to facial s

Abstract:
The diving behaviour of seven free-ranging harbour porpoises (Phocoena phocoena) was examined using time–depth recorders. In total, 8167 individual dives were recorded over 254 h. The longest period of data collection from an individual was 106.1 h. Mean dive depths and durations ranged from 14 ± 16 to 41 ± 32 m, and from 44 ± 37 to 103 ± 67 s, respectively. The maximum recorded dive depth and duration was 226 m and 321 s. This performance may not represent the maximum capacity of harbour porpoises but rather the maximum depth of the study area. Individual dives had similar rates of descent an

Abstract:
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. Much less is known about cooperative hunting in seemingly unsocial animals, such as the harbour porpoise (Phocoena phocoena (Linnaeus, 1758)). Using drones, we were able to record 159 hunting sequences of porpoises, out of which 95 sequences involved more than one po

Abstract:
Average values of morphological parameters for mature harbour porpoise (Phocoena phocoena) are presented. Variation in these parameters with body length was examined for a sample of 35 porpoise. Several parameters including fineness ratio, fluke aspect ratio, and the ratios of fluke area:body surface area and (body surface area)1/2:(body volume)1/3 were found to vary with body length. Fluke aspect ratio was inversely proportional to fluke sweep angle. The finding that many morphological parameters vary with length for harbour porpoise indicates the dependence of these parameters on age; this m

Harbour porpoises stranded around the Scottish coast throughout the year, with fatal attacks by bottlenose dolphins and pathological conditions being the main causes of death, there has been an apparent increase in the number of porpoises dying due to pathological conditions and starvation in recent years, although there was no evidence of any overall trend in the annual number of stranded porpoises.  Reproductive seasonality was found to occur and the mating and calving periods were estimated to take place between May and August, with gestation lasting approximately 11 months.

Abstract:
Harbour porpoises (Phocoena phocoena) are one of the most abundant small cetaceans in the world and, while they are extensively studied across most of their range, little is known about their biology in British Columbia, Canada. Recent management plans have identified a need to better understand the population structure of harbour porpoises in this region. I investigated the genetic population structure of harbour porpoises in British Columbia using mitochondrial DNA (mtDNA) and eight microsatellite loci. My findings are consistent with a single population of harbour porpoises inhabiting the c

Seventy-eight harbour porpoises, Phocoena phocoena, (33 females, 45 males) were obtained from the summer (June-September) cod fishery incidental-by-catch in the Gulf of St. Lawrence, and examined for the presence of cranial sinus nematodes. This is the first quantitative and in-depth study of the distribution of Stenurus minor (Kuhn, 1829) Baylis and Daubney, 1925 in the cranium of by-caught harbour porpoises. Stenurus minor was present in the cranial sinuses of all adult porpoises ($>$1yr, n = 66, x = 2362, range 87-8920) and absent in all young-of-the-year ($<$1yr, n = 12). Only fifth-stage

Abstract:
Whilst the harbour porpoise {Phocoena phocoena) is the most frequently observed cetacean in the UK, it is at risk from habitat degradation, pollution, incidental capture in fishing nets and anthropogenic disturbance. UK, European and international initiatives have highlighted the conservation need to obtain a better understanding of this species. This research, conducted over 5 years (1999-2004) aimed to further the scientific knowledge of the harbour porpoise in order to influence future conservation initiatives.
