Genetic variability and differentiation of three families containing 12 species of toothed whales mainly from the sea around Japan have been examined by starch-gel electrophoresis at 19 genetic loci encoding…
This paper describes the sonar sounds from four captive Neophocaena, two males and two females, which were tape recorded and processed with regard to their behaviour in the time and…
The early postnatal growth of bottlenose dolphins and finless porpoises was studied using 97 body length records of 61 individuals born in aquariums. The growth rates observed were similar to…
(...) This document attempts to gather together as much information as is available on the extent of current killings of small cetaceans throughout the world, and also to highlight some…
True porpoises are a morphologically distinctive and evolutionarily old group of odontocete cetaceans classified as the family Phocoenidae. They are distinct from members of the family Delphinidae, with which they…
The population biology of most phocoenid species is still rather poorly understood. It is important that we improve our knowledge in view of concerns which have been expressed in recent…
Catch statistics for 15 species of small cetacean are analysed, based on catch data collected for the 6 years from 1976 to 1981. Commercial catching of animals either by harpoon…
Two species of freshwater dolphin are known to have existed in the Yangtse River, China, for over two thousand years. One is a white form, the Baiji (Lipotes vexllifer), the…
In the course of a dissection of a cetacean belonging to the species Neophocaena asiaeorientalis, caught in the Changjiang (middle and lower reaches of the Yangtze river), nematodes were found…
