Hooligan Dolphins (VIDEO) Cell Press This video is under embargo. Please login to access this video. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption This video, taken by drone, shows adult male Indo-Pacific bottlenose dolphins (Tursiops aduncus) from a second-order alliance called the Hooligans. These three males spend time petting each other, e.g., using pectoral fins and tail flukes to rub against each other. These gentle contact behaviors play an important role in maintaining the strong social bonds between allied male dolphins.
