Bite Injuries of Grey Seals (Halichoerus grypus) on Harbour Porpoises (Phocoena phocoena)
Bite-like skin lesions on harbour porpoises (Phocoena phocoena) have been suspected to be caused by grey seals (Halichoerus grypus), and a few field observations have been reported. Bite-like skin lesions observed on stranded animals were characterized by two main components: large flaps of loose or missing skin and blubber with frayed edges and puncture lesions. Definitive demonstration of pre...
متن کاملDetection of grey seal Halichoerus grypus DNA in attack wounds on stranded harbour porpoises Phocoena phocoena
DNA was analysed from external wounds on 3 dead harbour porpoises Phocoena phocoena that were stranded in the Netherlands. Puncture wounds as well as the edges of large open wounds were sampled with sterile cotton swabs. With specific primers that target the mtDNA control region of grey seal Halichoerus grypus, a 196 bp DNA fragment was amplified from 4 puncture wounds. Sequencing of the fragme...
متن کاملThe Grey Seal (Halichoerus grypus) as a Predator of Harbour Porpoises (Phocoena phocoena)?
In September 2011, two harbour porpoises (Phocoena phocoena) presenting extensive traumatic lesions washed ashore in Belgium. Similar lesions, with large parts of skin and blubber missing, had not been recorded before on harbour porpoises in Belgium but were recently observed in a number of cases in neighbouring countries. We compared the lesions with the mouth and teeth structure of possible p...

متن کاملEcholocation signals of wild harbour porpoises, Phocoena phocoena.
Field recordings of harbour porpoises (Phocoena phocoena) were made in the inner Danish waters with a vertical array of three or four hydrophones. The back-calculated source level ranged from 178 to 205 dB re 1 muPa pp @ 1 m with a mean source level of 191 dB re 1 muPa pp @ 1 m. The maximum source level was more than 30 dB above what has been measured from captive animals, while the spectral an...
