Acoustic signals from free-ranging finless porpoises were recorded in the waters around Hong Kong during March 2000. Finless porpoises produced short-duration high-frequency clicks. Signal analysis showed finless porpoise clicks to…
The taxonomy of the finless porpoise (Neophocaena phocaenoides), while better-studied than that of many species of small cetaceans, still suffers from some uncertainties and a general lack of data from…
We studied the distribution and abundance of finless porpoises (Neophocaena phocaenoides) in Hong Kong and adjacent waters of China's Guangdong Province between September 1995 and November 2000. Vessel (50,194 km)…
Data on causes of death for finless porpoise (Neophocaena phocaenoides) specimens stranded in Hong Kong between 1995 and 2000 were evaluated. We diagnosed several causes of death, including fishing net…
To clarify population structure of finless porpoises (Neophocaena phocaenoides) in Japan, a sequence of studies have been conducted: a questionnaire survey and aerial sighting surveys to obtain information on porpoise…
The authors made 39 surveys (a total of 161 days) in the Tian-e-Zhou Oxbow of the Yangtze River, China, for observing 13 Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis) captured from…
Irrawaddy dolphins Orcaella brevirostris and finless porpoises Neophocaena phocaenoides are referred to as facultative freshwater cetaceans because they occupy both fresh- and nearshore marine waters. In Asia, the especially rapid…
From 5 March to 1 July, 1999 and 2000, we made six shipboard surveys for finless porpoises (Neophocaena phocaenoides) in the Inland Sea, which is believed to be inhabited by…
This study was concerned with the taxonomy of the Finless Black Porpoise. Morphological and biometric analyses of the body and skull measurements of Pakistani, Chinese and Japanese specimens revealed that…
The existence of at least two biological species of finless porpoises (Neophocaena phocaenoides and N. asiaeorientalis) was accepted only recently. Given the vulnerability of finless porpoises to human activities throughout…
