They may not be on Facebook or Twitter, but dolphins do, in fact, form highly complex and dynamic networks of friends, according to a recent study by scientists at Harbor Branch Oceanographic Institute (HBOI) at Florida Atlantic University. Dolphins are known for being highly social animals, and a team of researchers at HBOI took a closer look at the interactions between bottlenose dolphins in the Indian River Lagoon (IRL) and discovered how they mingle and with whom they spend their time.

Through intensive photo-ID surveys conducted along the IRL, which were carried out over a six- and-a-half year period, the researchers were able to learn about the association patterns as well as movement behavior and habitat preferences of some 200 individual dolphins.

In a paper recently published in the journal Marine Mammal Science, the team found that individual dolphins exhibited both preference and avoidance behavior – 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.

“One of the more unique aspects of our study was the discovery that the physical dimensions of the habitat, the long, narrow lagoon system itself, influenced the spatial and temporal dynamics of dolphin association patterns,” said Elizabeth Murdoch Titcomb, research biologist at HBOI who worked on the study with Greg O'Corry-Crowe, Ph.D., associate research professor at HBOI; Marilyn Mazzoil, senior research associate at HBOI, and Elizabeth Hartel. “For example, communities that occupy the narrowest stretches of the Indian River Lagoon have the most compact social networks, similar to humans who live in small towns and have fewer people with whom to interact.”

In addition to providing a unique glimpse into dolphin societies, this novel study provides important insight and knowledge on how dolphins organize themselves, who they interact with and who they avoid, as well as when and where.
