Did you know some cetaceans use "nets" to catch their food? Like humpback whales. They'll dive down and swim in a ring around their prey, blowing out bubbles as they go.
That rising ring forms a column that traps fish, allowing other whales in the group to swim up from below, mouths agape, through the bubble cylinder to feast.
It's an absolutely fascinating and beautiful thing to watch - and scientists have caught it on camera in a rare whale's-eye view.
In addition to drone footage showing a stunning overhead view of a pair of humpback whales (Megaptera novaeangliae) creating the bubble nets, marine biologists at the University of Hawaiʻi at Mānoa stuck cameras and sensors on whales using suction cups to collect a wealth of data on the fascinating behaviour.

I wonder if the Humpback whales circle in the opposite direction south of the equator.

The North Atlantic humpbacks will often splash their tails to create the bubbles, then dive, and then come up in the middle with their mouths open to catch the fish. They then push the water out through the baleen with their tongues, and swallow the fish. The seabirds know what is coming, and fly close so as to catch fish that escape the whales' open mouths.
