The Largest Animal Ever: The Blue Whale. 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.
Both were among the largest predatory mammals of all time. The largest member of the extinct Notoungulata, and the superorder Meridiungulata, was Toxodon. It was about 2.7 m (8 ft 10 in) in body length, with an estimated weight up to 1,415 kg (3,120 lb). Taeniolabis taoensis is the largest non-therian mammal known, at a weight possibly exceeding 100 kg. Notes
