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…

Eighty-one dead cetaceans of a variety of species and from British waters were examined for evidence of skin disease and 69% were found to be affected. The most common conditions…
Epidermal thickness and relative papillary height of the skin from the urogenital region were compared with values from the ventral aspect of the flipper and the mid-dorsal body wall. Data…
This study investigated how skin contributes to buoyancy control in the Florida manatee (Trichechus manatus latirostris), harbor porpoise (Phocoena phocoena), and bottlenose dolphin (Tursiops truncatus). Manatees are shallow divers and…
(...) In this study we used data collected from commercial dolphin-watching trips to determine whether there was any relationship between the probabilities of sighting bottlenose dolphins and harbor porpoises. Surveys…
(...) In the present study, we investigated whether this documented conflict between bottlenose dolphins and harbor porpoises in California affected harbor porpoise behavior within the nearshore environment where habitat overlap…
Toothed whales (crown Odontoceti) are unique among mammals in their ability to echolocate underwater, using specialized tissue structures. The melon, a structure composed of fat and connective tissue, is an…
Between 2007 and 2009, we witnessed three aggressive interactions between harbor porpoises and bottlenose dolphins in Monterey Bay, California. This is the first time such aggression has been documented in…
The diets of long-beaked common dolphins Delphinus capensis (n=117), dusky dolphins Lagenorhynchus obscurus (n=72), Burmeister's porpoises Phocoena spinipinnis (n=69) and offshore common bottlenose dolphins Tursiops truncatus (n=22) were determined based…
(...) 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…
