Kit, pretending to be a pool, was filmed

The humpback whale has one of the largest mouths on the planet and a corresponding appetite. A mammal the size of a bus can eat up to 2500 kilograms of fish a day.

A new study shows how humpback whales manage to attract so much fish to their mouths.

We know that in humpback whales, there are several tricks in stock that help to get food. For example, they make bubbles around the herring to force the fish to regroup, after which the seal can be swallowed whole.

Now biologists have learned the new tour of the humpback whale repertoire and even presented video evidence.

When seabirds, such as clubs or red-eyed birds, dive into the sea to catch herring, the whales open their mouth wide open to the surface of the water. The mouth of humpback whales turns into small ponds. The fish mistakenly takes them as shelters for hiding from birds and swims in the trap itself. Sometimes the whale pushes the fish in the right direction with the pectoral fins.

A video with a similar tip was filmed at northeast coast of the island of vancouver in canada. But for the first time, this behavior was observed in 2011. Since then, scientists have concluded that whales learn from each other and that this behavior could be considered a form of culture in marine mammals.

Marine biologists hope that the ability to develop behavioral strategies will help whales adapt to future climate change and inaccessibility to food.
