Blue whales observed at work

United States scientists have found blue whales perform underwater acrobatics to attack their prey from below.

The mammals are known for lunge-feeding - gulping up to 100 tonnes of krill-filled water in less than 10 seconds.

Using suction cup tags, researchers have recorded their surprising manoeuvrability.

They found that the whales roll 360 degrees in order to orientate themselves for a surprise attack.
