A blue whale can eat up to 4 tons of krill in a day
Lunge-feeding blue whales gulp enormous water volumes, then filter krill through baleen plates — sometimes packing up to about four tons of prey in a day.
That fuel runs the largest animal Earth has ever known. Tiny crustaceans, massed by the billion, become a giant’s grocery list.
Scale flips intuition: the biggest mouth often chases the smallest buffet. Ocean engineering eats sideways.
