Why can blue whales swim for 6 months without eating?

Explanation:
The tongue of a blue whale weighs as much as an elephant and the heart of this "sea giant" weighs as much as a car. A blue whale can eat 4 tons of crustaceans in 1 day. A blue whale can swim for 6 months without eating anything.

The waters of Antarctica possess a diverse population of plankton, crustaceans, and this is also the main food source for seals, penguins, fish, squid as well as whales. During the hunting season, usually in the summer of the year, blue whales will swim to the Antarctic waters to fill their giant bellies.

When they have absorbed a significant amount of energy reserves and more than they will use during the breeding season, the blue whale will spend all of this energy reserve moving to warmer waters because food sources there will be very scarce.
