Dolphin Social Network
view all sizes

This is a graph of a social network of frequent associations between 62 dolphins in a community living off Doubtful Sound,
New Zealand.

"Social animals have to take into consideration the behaviour of conspecifics when making decisions to go by their daily lives. These decisions affect their fitness and there is therefore an evolutionary pressure to try making the right choices. In many instances individuals will make their own choices and the behaviour of the group will be a democratic integration of all decisions. However, in some instances it can be advantageous to follow the choice of a few individuals in the group if they have more information regarding the situation that has arisen."
