Most people believe that the largest animals to ever exist on Earth were the dinosaurs. However, one of the largest land dinosaurs, the sauropod Argentinosaurus, weighed only about 180,000 pounds (81,647 kg). That's little more than half the size of an adult blue whale. It makes a lot of sense that the world's largest animal would be a sea creature. Land animals have to support their own weight, whereas sea creatures get some help from the water. It is believed that at one time there were more than 200,000 blue whales.
Best Answer: No, it is Baleonoptera musculus. It is a marine mammal belonging to the suborder of baleen whales. At up to 33 metres (110 ft) in length and 181 metric tonnes (200 short tons) or more in weight, it is believed to be the largest animal to have ever lived on Earth, though some recent, albeit controversial, dinosaur discoveries may contradict this long-held belief.
