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.
The blue whale is the largest animal alive on Earth today, although the exact maximum size is something of a moving target in the literature. This prodigious species is thought to be capable of reaching 110 feet in length, and the largest scientifically verified individuals on record are 89 to 98 feet long.upersaurus, Argentinosaurus, and Diplodocus were the largest creatures to ever walk the Earth, stretching more than 100 feet from their pencil-like teeth to their sinuous tails. But that âwalked the Earthâ clause is important.
