Courtesy Currier & IvesWord on the street is that sperm whales may have individual names. I hope so, frankly, because I'm sick of calling them ... that.
Sperm whales, it seems, have calls that are unique to the region they live in. So whales in the Caribbean might have a different call than whales living in the South Pacific. But there are parts of sperm whale calls that are, on the surface, the same in whales around the world.
I say, "on the surface" not as some ocean-related pun, but because there's a part of the whale's call—five clicks at the beginning of a call—that seem to be totally unique to individual whales. All whales make the five clicks, but if you analyze the sound in detail, there are actually subtle variations in the sounds that are unique to the whale making them. Because it comes at the beginning of each phrase, or "coda string," and because the variations are perceptible from every direction (some whale calls sound different depending on how the listener is oriented to the caller), some scientists think that the clicks could represent the "names" of individual whales, who are identifying themselves as they call out.
Pretty neat, huh?
PS—"Pretty neat," but not completely neat, because I probably can't distinguish between the whales' clicks. Here, then, is a short list of names for any whales interested in adopting more standard monikers:
There are, like, dozens of other possible names. These are just the first to come to mind.
