But do you know which animal has got the title of “The largest animal on the earth.” This creature is, even more, bigger than the largest dinosaurs ever found on earth. That creature must be well known to you. The creature is “Blue Whale,” (Balaenoptera musculus) largest animal on the earth, is a marine mammal, reaching a confirmed length of 29.9 metres (98 feet) and weight of 173 tonnes (173,000 kg). A female blue whale measuring the length of 110 feet has been recorded in 1909 at Grytviken, South Georgia in the South Atlantic.
