what do blue whales eat
What do blue whales eat? The blue whale is the biggest animal in the world, but strangely, it survives by eating very small creatures! These tiny animals are called krill, which look like very small shrimp and are around 1-2cm long. An adult whale can eat up to 40 million krill a day or around 8,000 lbs. Blue whales can only eat small prey because they have a very narrow oesophagus (throat). Watch a video of a blue whale below:
