 Do
you know our lovely Dolphin friends have their own names? Researchers
from the University of St Andrews recently found that bottlenose dolphins call
each other by name. How? They use unique whistles to call one another.
The research found that when dolphins are separated, they produce signature sounds to call
out each other. Each dolphin recognizes whether the sound is for
them or not, and react to it. In other words,
the whistle sound plays a role as a name of
the dolphins. In addition, since the distinctive sound is used
very often, dolphins in the same group are very familiar with the
sound and are able to mimic that sound.
 In an experiment
conducted by the University
of St Andrews, mother dolphins that were separated from their calves
copied the calves’ whistle sounds to join them. Then, the offspring
came to their mothers.
Dolphins are the only animals that use sounds to call each other like
human beings. When you go
to the zoo, why don’t you blow a whistle to meet them? |
