Scientists testing/messing with dolphins at Disney EPCOT have taught them to sing the Batman theme song:
"The dolphin was reinforced for producing a specific rhythm to a specific object," says Harley.
"For example, when we presented him with a Batman doll, he received a fish for producing a specific rhythm, in this case, a short sound and then a long one."
"If you recall the original Batman TV series musical intro you'll probably remember the way they sang 'Bat-maaaaaaaan'," she adds.
The dolphin spontaneously vocalised to the rhythms, so the researchers started to reward the male with fish whenever it matched its 'singing' to the rhythms.
By the end of the studies, the scientists could show an object, such as the Batman doll, which represented a certain rhythm-vocalisation combo to the dolphin, and it would create the correct sounds both vocally and using the switch.
