The largest animal in existence is the blue whale. The blue whale (Balaenoptera musculus) is a marine mammal. With a length of 30 meters and a weight of 180 tons or more, it is the largest animal ever known. The blue whale's tongue weighs about 2.7 tons, the average size of an Indian elephant, and its heart weighs about 600 kg and is the largest known in any animal. Not only is the blue whale's heart size comparable to that of a Mini Cooper, but it's also comparable in weight.
