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.
1 The largest species in terms of weight is the hippopotamus (Hippopotamus amphibius), native to the rivers of sub-Saharan Africa. 2  They can attain a size of 4,500 kg (9,900 lb), 4.8 m (16 ft) long and 1.66 m (5.4 ft) tall. The largest bear, and possibly the largest known mammalian land carnivore of all time, was Arctotherium angustidens. 2  The largest specimen yet found is estimated to weigh up to 1,600 kg (3,500 lb) and stood up to 3.4 m (11 ft 2 in) tall on the hind-limbs.
