Humpback whales are organizing in huge numbers, and no one knows why http://pops.ci/DEYPA6



____ The world is ending and only the whales know. At least, that’s one explanation. Humpback whales are normally pretty solitary—scientists used to call groups of 10 to 20 “large.” Now they’re congregating in groups of 20 to 200 off the coast of South Africa. Something is definitely going on here, but so far experts are stumped.

In fact, Humpback whales aren't supposed to be hanging out in that region in the first place. Humpbacks migrate up to tropical waters to breed, but they typically feed down south in the icy waters of Antarctica this time of year. Yet scientific expeditions keep seeing these super-pods (not to be confused with super PACs, which are equally giant but much more dangerous), which were finally compiled and published at the beginning of March in the journal PLOSone. The researchers have a few ideas about why the humpbacks are organizing, but no clear answers yet. So far the consensus seems to be: this is pretty freakin’ weird...

These enormous whale congregations are clearly for feeding, at least in part, but no one is really sure why there are so many of them. It seems to be a recent phenomenon unique to the last five years or so, so it could be that burgeoning whale populations are enabling these teeming masses yearning to breath free. At one point about 90 percent of the world’s humpbacks had been hunted down, but they've been on the rise since becoming a protected species in 1996. Maybe humpbacks were always this social, and there just weren’t enough of them for us to notice.

Or maybe they just weren’t doing it in areas where we could see them. If hundreds of whales were gathering smack in the middle of the Pacific Ocean, we probably wouldn't see or hear them (even though their songs can be heard from 20 miles away). And if a whale sings in the ocean and there’s no one there to hear it, it definitely still made a sound.

Perhaps they’re trying to tell us something, Like the dolphins who do a double-backward somersault through a hoop while whistling the Star Spangled Banner, the whales may be sending us a message that we’re misinterpreting as an adorably sophisticated trick. The oceans are warming, the seas are rising, and maybe—just maybe—the whales have had enough. They’ve gathered as many young humpbacks as possible to come together and send one final message: so long, and thanks for all the krill. Or maybe they're talking to a giant space probe. Who knows.
