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 animal ever known to have lived. By comparison, one of the largest known dinosaurs of the Mesozoic Era was Argentinosaurus, which is estimated to have weighed up to 90 tonnes (99 short tons), comparable to the average of blue whale.
