The blue whale is the largest animal known ever to have existed. [42] [43] [44] Some studies have estimated that certain shastasaurid ichthyosaurs and the ancient whale Perucetus could have rivalled the blue whale in size, with Perucetus also being heavier than the blue whale with a mean weight of 180 t (180 long tons; 200 short tons).
Perucetus is the largest Eocene whale measuring about 17–20 meters (56–66 ft) long. Some researchers claim that it may have rivaled or exceeded the modern blue whale in weight, partly due to the incredibly thick and dense bones this animal possessed, coupled with its already great size, while others argue that it was much lighter.

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
Size of Paraceratherium (dark grey) compared to a human and other rhinos (though one study suggests Palaeoloxodon namadicus may have been a larger land mammal). The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
The largest size this species can attain is 4,500 kg (9,900 lb), 4.7 m (15 ft) in total length, and 1.85 m (6.1 ft) tall at the shoulder. [91] It is slightly larger than the Indian rhinoceros (Rhinoceros unicornis), which can range up to a weight of 4,000 kg (8,800 lb). [92] The extinct Elasmotherium sibricum was the largest rhino to ever exist ...
The sperm whale's brain is the largest in the world, five times heavier than a human brain. The sperm whale brain is the largest known of any modern or extinct animal, weighing on average about 7.8 kilograms (17 lb) [61] [62] (with the smallest known weighing 6.4 kilograms (14 lb) and the largest known weighing 9.2 kilograms (20 lb)), [44] [45 ...
Size of Baird's beaked whale compared to an average human Size of Arnoux's beaked whale compared to an average human Size of Sato's beaked whale compared to a human. The two established species, Baird's and Arnoux's beaked whales, have very similar features and would be indistinguishable at sea if they did not exist in disjoint locations. [33]
The fin whale (Balaenoptera physalus), also known as the finback whale or common rorqual, is a species of baleen whale and the second-longest cetacean after the blue whale. The biggest individual reportedly measured 26 m (85 ft) in length, with a maximum recorded weight of 77 to 81 tonnes (85 to 89 short tons ; 76 to 80 long tons ).
