Livyatan is the largest fossil sperm whale discovered, and was also one of the biggest-known predators, having the largest bite of any tetrapod. [ 1 ] [ 8 ] Diagram comparing the upper and lower size estimates of Livyatan (bottom three) with the size of mature sperm whales, including one of the largest individuals recorded (top three), and a human
They calculated that the ancient giant weighed somewhere between 94 and 375 tons (85 and 340 metric tons). The biggest blue whales found have been within that range — at around 200 tons (180 ...

The largest known New World monkey was Cartelles, which is studied as specimen of Protopithecus, weighing up to 34.27 kg (75.6 lb). Caipora bambuiorum is another large species, weighing up to 27.74 kg (61.2 lb). [231] The largest omomyids were Macrotarsius and Ourayia from the Middle Eocene. Both reached 1.5–2 kg (3.3–4.4 lb) in weight. [232]

Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the largest known animal that has ever lived. The sperm whale is the largest toothed predator on Earth.
