| Research Abstract |
Two social behaviors, physical contact and synchrony of odontocetes were studied by using underwater observation of wild dolphins, observation of captive dolphins and biologging system. The results suggest that synchronous breathing is a component of an affiliative social behaviour in Indo-Pacific bottlenose dolphins. The results also show the differences in social contact with flipper of Delphinidae and that of Phocaenidae. Finless porpoises seemed to have undeveloped social structure in previous study, however, our results suggest that they form associations with particular individuals.
