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.
The blue whale is the largest creature to have ever lived on earth! One of the most important reasons that whales have become so large is they have more space - more room to roam. Remember: over 70% of the earth is covered in ocean water.
