it would’ve scared the fuck out of me holy shit that’s big
So for anybody who doesn’t know, that ring of bubbles you see coming up before the humpback does is a “net” that the whale creates by swimming in a circle and blowing the bubbles from its blowhole. The bubble net disorients the krill/small fish/whatever and corrals them into one spot so that the whale can lunge up and feed as you see it doing. It’s most often done cooperatively in groups, and a whole bunch of whales will lunge up at once.
