Dolphins 'remember friends' whistles' for decades

They are such beautiful animals.
Bottlenose dolphins can remember each other's signature whistles for more than 20 years, a study said Wednesday -- the longest social memory ever observed in an animal.
Elephants have long been credited with the animal kingdom's most prodigious memory, but evidence for that was anecdotal, said the study's author Jason Bruck of the University of Chicago's Institute for Mind and Biology.
Bruck claims to have compiled the first study showing social recognition in an animal persisting beyond two decades -- possibly "the longest pure memory of any kind in a non-human species".
