I don't recognize the name, but the whistle is familiar:
Dolphins have long impressed people with their sharp minds and humanlike traits, such as calling each other by name, goofing off and even understanding numbers. Now a scientist has found that the mammals can recognize an old friend’s whistle, even after they have been apart for 20 years — the longest social memory ever recorded for a non-human.
So, dolphin is the new elephant? Sort of depressing to realize dolphins have better memories than I do. Bet I can goof off better, though.
