The blue whale, the largest animal on Earth, can consume up to 4 tons (8,000 pounds) of krill in a single day. To sustain its massive size, a blue whale needs to consume around 1.5 million calories daily, which is equivalent to approximately 40 million krill. Despite their enormous appetite, blue whales primarily feed during summer months when krill populations are at their peak. To catch prey, they engulf large amounts of water and then filter it out through baleen plates, retaining the tiny krill as food. This remarkable feeding adaptation allows blue whales to thrive and maintain their incredible size.
