Estimates suggest that because calves require 2–4 kilograms (4.4–8.8 lb) milk per kg of mass gain, blue whales likely produce 220 kilograms (490 lb) of milk per day (ranging from 110 to 320 kilograms (240 to 710 lb) of milk per day). [96] The first video of a calf thought to be nursing was filmed in New Zealand in 2016. [97]
In 2023, paleontologists estimated that the extinct whale Perucetus, discovered in Peru, may have outweighed the blue whale, with a mass of 85 to 340 t (94–375 short tons; 84–335 long tons). [8] However, more recent studies suggest this whale was much smaller than previous estimates putting its weight at 60 to 113 tonnes. [9]
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. [11] [12] [13] It is estimated that this individual could have a mass of 250 tonnes or more.
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]
