A. This long-held view of dolphin intelligence has now been proved incorrect.
A. This long-held view of dolphin intelligence has now been proved incorrect. B. On hearing the dolphin it knew, the dolphin approached the loudspeaker which was playing the recording, it hovered around whistling at it, trying to get it to whistle back. C. The familiar calls often would perk up the dolphins and elicit an immediate response. D. The pair had last lived together at Dolphin Connection in the Florida Keys when one of them was 2 and the other was 4. E. It turns out the aquatic mammals put us land-dwellers to shame in the long-term memory department. F. This identifying sound is even more reliable than features used by humans to recognise one another. G. We don’t know yet if the name makes a dolphin picture another dolphin in its head. H. The dolphins at these sites had periodically spent time in each other’s company over a long period, and there were fully verified records to prove this. I. They found that dolphins not only recognise each other by their whistles, but often mimic a companion’s unique whistle to get them to respond almost the same way humans do greeting each other. J. So probably by remembering individual whistles, dolphins can remember which others were friendly or not, then choose to join or avoid them. K. According to the latest research by Dr Jason Bruck at the University of Chicago dolphins have the exceptional ability to recall other dolphins by the distinctive whistle that acts as their name.
