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.
Basilosaurus was once recognized as one of the largest known extinct cetaceans at 18 metres (59 ft) in length. The largest fossil toothed whale was the Miocene whale Livyatan melvillei which was estimated to be 13.5-17.5 meter in length. One notable feature of L. melvillei was its teeth which were 36 cm long and is unmatched by any other animal, extinct or alive.
