How much do whales eat? As you’d imagine, it’s a lot. Smithsonian scientist Nick Pyenson took part in new research that indicates that in one day a blue whale can eat about 16 tonnes (or metric tons) of krill. That’s about the same as 8,800 quarter-pound burgers! When considering all the blue whales that live today, it means blue whales eat over half a million tonnes of krill every year.
