Not exactly, but it makes a good title.

Among sperm and killer whales, Dr. Whitehead said, “there’s a feeling of what one might call ethnicity or cultural identity, of saying, ‘This is my clan, and it’s different from the others.’ ”

One way whales express their ethnicity is through dialect. Every clan has its signature call, and in regions of the ocean where two clans overlap, the differences between calls become exaggerated.

“It’s like if you’re Irish and you run across someone who is Scottish or Welsh,” said Dr. Whitehead. “You’ll speak with an even stronger Irish accent to make it really clear whose group you belong to.”
