A dolphin that lives alone among harbor porpoises has been found to change its vocalization in an attempt to pick up the langue of its neighbors.

This has never been confirmed in the wild before, but must be taking place since the dolphin has completely abandoned its normal sounds for the porpoises' clicks—even when she's completely alone.

It may be that Kylie, a common dolphin in the Firth of Clyde, Scotland, isn't trying to talk to the porpoises, but that she identifies as one. After all, she often lives alone in the Firth, and biologists believe she may have been separated from her natal pod during a storm.
