Ukrainian polar explorers in Antarctic a group of humpback whales is often spotted hunting with a bubble net.
Stink twist spirals around a school of fish or krill, forcing the prey to gather, and then they swallow it, they tell at the National Antarctic Science Center.
Groups of humpback whales usually participate in such hunts, but researchers have observed cases where a single whale made a bubble net.
Biologist Vadym Tkachenko managed to record such a moment on video.
"The giant made a ring around the prey and floated up through the center. At this moment, the hunchback was scooping up everything in its path thanks to the large throat folds.
They straighten and allow a large volume of water to be collected, which the whales then push out through the baleen plates, and the fish and krill eat", - polar explorers write.
Although humpback whales have a large mouth, they can swallow a limited amount of food because they have a narrow throat. At most, it stretches only to the size of a watermelon.
