how is food stored for a blue whale?

Blue whales primarily feed on small shrimp-like animals called krill, which they consume in vast quantities. They store energy by accumulating blubber, a thick layer of fat beneath their skin, which provides insulation and energy reserves. During feeding season, they can consume up to 4 tons of krill daily, and their bodies convert this energy into blubber for use during migration or times of scarcity. Unlike typical food storage, blue whales rely on their blubber as a means to store energy rather than physically storing food.
