MARATHON, Florida Keys – Do bottlenose dolphins work together to perform and carry out the tasks?
"Yes", says a study by marine mammal researchers in the Center & # 39; Dolphin Research in Keys & # 39; Florida.
The project & # 39; almost a year show that dolphins cooperate to perform work together.
The research, carried out by & # 39; & # 39 collaboration with, a scientist & # 39; University & # 39; of Western Australia, studied pairs & # 39; Dolphins enjoying a lagoon & # 39; Florida Keys to reach and press buttons under the black water. The buttons were wired with & # 39; computer on the surface to record the actions and the difference in time when the two dolphins push buttons.
"We wanted to see if dolphins can cooperate with & # 39; actively", said Dr. Kelly Jaakkola (YAH & # 39; KO-lah), the director & # 39; DRC research. "The game was that the dolphins had to swim across the lagoon and press the buttons at the same time … specifically, a time window & # 39; second time."
F & # 39; some tests, the dolphins were sent together, Jaakkola noted. F & # 39; others, there were delays in sending one partner. The other looks, so that both their Pressing buttons simultaneously.
"The Dolphins succeeded in not only & # 39; this test, were amazing", she said. "By the end, the difference in time between the presses their buttons was only & # 39; 370 milliseconds.
"This is about a third of a second," Jaakkola added. "That kind of & # 39; precision proves cooperating … only then are coordinated with & # 39; & # 39 active manner, super-accurate way to synchronize their behavior."
What is known as "synchronization behavior", shown by hanging dolphins in the wild when co bathing or their feed, x & # 39; likely as general cognitive ability that may apply to many activities, Jaakkola said.
The DRC researchers are also studying whether the dolphins use vocal signals or other ways to coordinate actions.
The results of & # 39; the study were published in the journal & # 39; biological research & # 39; The Royal Society, a scientific academy based in the UK.
The stranded dolphins can understand the role of partner in & # 39; cooperative work.
