Blue whales execute 360-degree rolls to capture prey
World’s largest predators – the blue whales – execute acrobatic 360-degree rolls while feeding on their small crustacean krill prey.
Blue whales are now the only known rorqual whales – the largest group of baleen whales – that can complete a full circle roll. Other whales only go around 90-150 degrees.
Considering that blue whales grow close to 100 feet long and can weigh around 397,000 pounds, the feat is quite an achievement. The massive mammals manage the trick in two steps, the ‘Discovery News’ reported.
