(...) Six complete [N. phocaenoides] (3 male, 3 female) have been collected in the Karachi Waters and in the Indus Delta Region by G. PILLERI. The testes and ovaries of…
Two species of cetaceans live in the Yangtze river (Changjiang R.): Lipotes vexillifer (MILLER, 1918) and Neophocaena asiaeorientalis (PILLERI and GIHR, 1972). Both species are only found in the middle…
Data on the occurrence of harbour porpoises (Phocoena phocoena) in German waters from 1988 to 2002 were collected from dedicated aerial surveys, incidental sightings and strandings. Aerial surveys conducted in…
We investigated the occurrence of harbour porpoises in the North Sea off Schleswig-Holstein by conducting aerial surveys with emphasis on calves. Fourteen per cent of the sighted porpoises off the…

North Atlantic harbour porpoises Phocoena phocoena (L.) face considerable energetic challenges, as they are relatively small marine mammals with an intense reproductive schedule and a cold-water habitat. Post-natal growth of…
Two species of small cetaceans, the Indo-Pacific hump-backed dolphin and the finless porpoise, occur year-round in waters of the Hong Kong Special Administrative Region. Research conducted from September 1995 to…
Social behaviors are poorly known for the critically endangered Yangtze finless porpoise (YFP, Neophocaena asiaeorientalis asiaeorientalis). Here, group composition and dispersal patterns of the YFP population living in the Poyang…
Ships and wind turbines generate noise, which can have a negative impact on marine mammal populations by scaring animals away. Effective modelling of how this affects the populations has to…
