Causes of mortality and parasites and incidental lesions in harbour porpoises (Phocoena phocoena) from British waters
Baker, JR; Martin, AR
Veterinary Record (1992)
Detailed post mortem examinations were carried out on 41 harbour porpoises (Phocoena phocoena) found dead on the coast of the United Kingdom. The commonest causes of death were entanglement in…
Investigations on the osteology and the functional morphology of the flipper of whales and dolphins (Cetacea)
Benke, H.
Investigations on Cetacea (1993)
Of the 79 recent species of cetaceans 51 have been examined relative to the osteology of the flipper and the scapula and, in addition to this, video-recordings of 13 different…
Cytoarchitectonic studies of the cerebral cortex of the harbour porpoise, Phocoena phocoena (Linne, 1758)
Behrmann, G.
Investigations on Cetacea (1993)
The olfactory system of the harbour porpoise is reduced but has a function. The visual system of the harbour porpoise is badly developed, and its inferior to the one of…
