A team from the University of St Andrews in Scotland found that when the animals hear their own call played back to them, they respond.
The study is published in the actions of the National Academy of Sciences. Dr Vincent Janik, from the university's Sea Mammal Research Unit, supposed Dolphins live in this three-dimensional environment, offshore without any kind of landmarks and they need to stay jointly as a group.
