Aquatic Mammals (1990)
This study shows that in Bottlenose dolphins and in Harbour porpoises the presence of marginal papillae is age related. In Bottlenose dolphins the papillae disappear around the age of 16…

Examination of 95 Dall's porpoise specimens incidentally caught in gill nets, and 4 collected as beach strandings, indicate significant sexual dimorphism and developmental variation in several aspects of external morphology…
Types of fisheries and exploitation of small cetaceans in Argentinian waters are reviewed. During the study period, live-captures included five specimens of Cephalorhynchus commersonii for Germany, while eight of Tursiops…
Results of an aerial sightings survey conducted in coastal (within the 600m depth contour) Icelandic waters from 27 June-20 July 1986 are presented. The survey followed a predetermined random grid,…
Several species of small cetaceans are captured by fishermen in Peruvian coastal waters and used for human consumption. A large directed fishery exists for one species, the dusky dolphin Lagenorhynchus…
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…
(...) During August and September 1986 a cooperative research effort was organized between a consultant of the IUCN/UNEP Burmeister's Porpoise Project (KVW) and the head of the marine mammal and…
(...) 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…
For the first time in cetaceans, the development of the terminalis system and its continuity between the olfactory placode and the telencephalon has been demonstrated by light microscopy. In the…
(...) Although various sensory mechanisms are present in cetaceans, special navigational problems occur when animals are in a pelagic environment which can minimize available cues. Dawbin (1966) has observed that…
