Humpback whales are resourceful hunters. Researchers from Alaska have now discovered everything the whales come up with to catch their prey.
A humpback whale is a good twelve meters long and weighs approximately 30 tons. Since humpback whales also swim vast distances and have to withstand water resistance, they consume enormous amounts of energy. The energy they need to feed themselves in order to survive. That is why they have developed creative hunting techniques. Humpback whales use their pectoral fins to round up krill and small fish and then direct them towards the mouth by flicking their fin, according to biologists at the University of Alaska Fairbanks. The whales first create a “fence”, with which they catch their prey. The whales blow oxygen out of their blowhole in such a way that the air bubbles form a kind of barrier. The fish are then trapped within this barrier.
