[Ans] What is the largest known creature that ever existed on planet earth?

Step 1 : Introduction to the question "What is the largest known creature that ever existed on planet earth?"

At 98 feet in length and 180 metric tons or more in weight, the blue whale is the largest known animal to have ever existed. The Blue Whale’s tongue weighs around 5,952 pounds, about the size of an average Asian Elephant and its heart weighs about 1,300 pounds and is the largest known in any animal. Not only is the heart similar in size to a mini-cooper car, but it is also comparable in weight. By comparison, the largest known dinosaur of the Mesozoic Era was Argentinosaurus, which is estimated to have weighed up to about half the weight of the largest blue whales.
