We know dolphins are very smart. Now new research finds that bottlenose dolphins, call each other with specific names when they become separated.
According to Discovery News report, lead author Stephanie King of the University of St. Andrews Sea Mammal Research Unit, said:
“When animals were separated from a close associate, they made replicas, which confirms our theory that dolphins imitate another animal’s trademark whistle when they desire to reconcile with that individual.”
Dolphins in captivity may learn new signals and refer to items, and it’s possible that they can employ signature whistle copies to name or refer to individuals, which is a human language skill!
Dolphin whistles can be detected up to 20 km away (12.4 miles) depending on water depth and whistle frequency.
