Humpback whales are organizing in huge numbers, and no one knows whyThe 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. [ link to www.msn.com] Quoting: ~Jazzy~  Fuku? Could be. I also wondered if it might have something to do with Antarctica because of this part, from the link. Humpbacks migrate up to tropical waters to breed, but they typically feed down south in the icy waters of Antarctica this time of year.Killer whale predation Visible scars indicate that killer whales can prey upon juvenile humpbacks, though until recently hunting had never been witnessed and attacks were assumed to be superficial in nature.[108] However, a 2014 study off Western Australia[109] observed that when available in large numbers, young humpbacks can be attacked and sometimes killed by orcas. Moreover, mothers and (possibly related) adults escort neonates to deter such predation. The suggestion is that when humpbacks suffered near-extinction during the whaling era, orcas turned to other prey, but are now resuming their former practice. There is evidence that humpback whales will defend against or attack killer whales who are attacking either humpback calves or juveniles as well as members of other species
