Florida dolphins use their own forms of social media to choose their friends
Just like human beings, dolphins form highly complex and dynamic social networks, according to a recent study by scientists at Harbor Branch Oceanographic Institute (HBOI) at Florida Atlantic University.
The researchers studied the interactions between some 200 bottlenose dolphins in the Indian River Lagoon (IRL), a 156-mile long estuary located on Florida’s east coast.
They discovered how the dolphins mingle and with whom they spend their time. They may not have Facebook or Twitter but they do have association patterns as well as movement behaviour and habitat preferences.
The IRL lagoon is long and narrow and composed of three distinct water bodies; Mosquito Lagoon, Banana River, and the Indian River. There are five inlets and one lock (Cape Canaveral lock) connecting the IRL to the Atlantic Ocean.
Researchers from HBOI have been conducting photo identification studies of IRL bottlenose dolphins since 1996, identifying more than 1,700 individual dolphins.
In their paper recently published in the journal Marine Mammal Science, the team found that individual 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.
“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,” says Elizabeth Murdoch Titcomb, research biologist at HBOI who worked on the study.
“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, the study provides important insight and knowledge on how dolphins organise themselves, who they interact with and who they avoid, as well as when and where.
It also gives scientists and resource managers the roadmap needed to understand how dolphin populations perceive and use their environment, and how social networks will influence information transfer and potentially breeding behaviour and disease transmission.
