Balaenoptera sibbaldii Sars , 1875. The blue whale ( Balaenoptera musculus) is a marine mammal and a baleen whale. Reaching a maximum confirmed length of 29.9 meters (98 ft) and weighing up to 199 tonnes (196 long tons; 219 short tons), it is the largest animal known ever to have existed.

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. [15] [60] [61] The extinct whale species Perucetus colossus was shorter than the blue whale, at 17.0–20.1 meters (55.8–65.9 ft) but it is estimated to have rivaled or surpassed it ...

By comparison the average blue whale penis is nearly 3 times the size of that of a sei whale. Specimen measurements indicate that a blue whale measuring 21.6 metres (71 ft) in length had a vestigial mammary slit of 40.6 centimetres (16.0 in) width and 48.2 centimetres (19.0 in) length, with a penis measurement of 1.83 metres (6.0 ft).
By comparison, the modern sperm whale length measures on average 11 m (36 ft) for females and 16 m (52 ft) for males, with some males reaching up to 20.7 m (68 ft) long. The large size was probably an anti-predator adaptation, and allowed it to feed on larger prey.
If the upper size estimates for Bruhathkayosaurus are accurate, it would even rival the size of the largest recorded blue whale. Mature blue whales can reach 30 m (98 ft) in length, and the record-holder blue whale was recorded at 173 tonnes (190 short tons), with estimates of up to 199 tonnes (220 short tons).
Whales are fully aquatic, open-ocean animals: they can feed, mate, give birth, suckle and raise their young at sea. 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
