How much plankton does a blue whale eat?

Blue whales are filter feeders and consume enormous amounts of plankton, mainly krill, daily. Here's a breakdown:

* Daily intake: A blue whale can consume up to 40 million krill in a single day.

* Weight: This translates to approximately 4 tons of krill per day.

* Volume: That's equivalent to about 3,600 gallons of water containing krill.

Keep in mind:

* This is an estimate, and the actual amount a blue whale eats can vary based on factors such as:

* The abundance of krill in the area.

* The size and age of the whale.

* The season and water temperature.

To give you a better sense of scale:

* A blue whale can be as long as a Boeing 737 airplane.

* Their mouths can be as wide as a school bus.

* They have baleen plates in their mouths that act like a giant strainer, allowing them to filter out krill and other small organisms from the water.

Blue whales are truly remarkable animals!
