Dolphins 'mimic call of companions'

[Still Waters]

Dolphins mimic the distinct whistles of their closest companions as a way of tracking them, according to researchers.

A team of marine biologists from the University of St Andrews studied the vocal signatures of the mammals.

Their findings suggested that dolphins mimic those they are close to and want to be reunited with.
