Dolphins too have social networks

New York: They do not log in to Facebook or Twitter, but dolphins do, in fact, form highly complex and dynamic networks of friends, a new research has found. The surveys conducted along the Indian River Lagoon (IRL) over a six and a half year period revealed that individual bottlenose dolphins exhibited both preference and avoidance behaviour - so just like humans, they have dolphins they like and associate with and ones they avoid. The study also found that IRL dolphins clustered into groups of associated animals, or "communities," that tended to occupy discrete core areas along the north-south axis of the lagoon system.
