15 of the Largest Animals in the World. The blue whale (Balaenoptera musculus) is a marine mammal belonging to the suborder of baleen whales. At 30 metres (98 ft) in length and 180 metric tons (200 short tons) or more in weight, it is the largest known animal to have ever existed.
Blue whales are the largest animal ever known to have lived, even larger than the dinosaurs who once roamed the Earth. In fact, the longest blue whale ever measured was 111 feet long â approximately the length of three school buses parked end to end.
