Oregon State scientists captured some rare blue whale feeding behavior from a research drone. Whales are the largest creatures on earth, and they get their energy by consuming some of the smallest creatures in the sea. This video shows how they make choices about what’s worth eating.

Blue whales, measuring up to 30 metres ong and weighing 170 metric tonnes , are the largest animals in the world, and have been captured on film making strategic decisions on how to get their next meal of krill.

The video below taken off New Zealand by scientists from Oregon State University shows just how the whales pick and choose their meals.The whale bypasses certain krill patches – presumably because the nutritional payoff isn’t sufficient – and targets other krill patches that are more lucrative.

Every time a blue whale opens its mouth, it’s like putting on the brakes, so it slows way down. These animals have to make decisions about what it’s worth opening their mouths for.
