The blue whale is the largest animal known ever to have existed. [43] [44] [45] 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).
Blue whale penis. As the largest animal that has existed, the blue whale has the largest instance of several body parts. Its tongue weighs around 2.7 tonnes (3.0 short tons; 2,700 kg). [1] Its mouth is large enough to hold up to 90 tonnes (99 short tons; 90,000 kg) of food and water. [2]
The largest animal currently alive is the blue whale. The maximum recorded weight was 190 tonnes (209 US tons) for a specimen measuring 27.6 metres (91 ft), whereas longer ones, up to 33 metres (108 ft), have been recorded but not weighed. [1] [2] [3] It is estimated that this individual could have a mass of 250 tonnes or more.
The blue whale diverged from other Balaenopteridae (including fin and northern minke whales) between 5 and 10 million years ago, and the oldest fossil representing something similar to today’s ...
Rorquals (/ ˈ r ɔːr k w əl z /) are the largest group of baleen whales, comprising the family Balaenopteridae, which contains nine extant species in two genera.They include the largest known animal that has ever lived, the blue whale, which can reach 180 tonnes (200 short tons), and the fin whale, which reaches 120 tonnes (130 short tons); even the smallest of the group, the northern minke ...
The 17–20-meter (56–66 ft) skeletal structure alone would have accounted for 5.3–7.6 t (5.2–7.5 long tons; 5.8–8.4 short tons), which is already two to three times the weight of the skeleton of a 25 m (82 ft) long blue whale. The weight estimates are based around the relation between skeletal and total body mass of modern mammals.
The heaviest archeocete, and possibly the heaviest known mammal was Perucetus, with weight estimated at 85–340 t (84–335 long tons; 94–375 short tons), while length is estimated at 17.0–20.1 meters (55.8–65.9 ft), [111] possibly rivaling the Blue Whale in mass. However, Motani and Pyenson in 2024 argued that it is extremely difficult ...
