Sei whale skeleton. The sei whale is the third-largest balaenopterid, after the blue whale and the fin whale. [28] Adults usually weigh between 15–20 t (15–20 long tons; 17–22 short tons). [29] They exhibit sexual dimorphism, with females outweighing and being longer than their male counterparts. [27]
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.
They include the largest animal that has ever lived, the blue whale. They take their name from a Norwegian word meaning "furrow whale"; all members of the family have a series of longitudinal folds of skin running from below the mouth back to the navel (except the sei whale, which has shorter grooves).
The largest beaked whale is the Baird's beaked whale (Berardius bairdii) at up to 14 tonnes and 13 m (43 ft) long. [38] The largest of the beluga and narwhal is the beluga whale (Delphinapterus leucas). Adult male beluga whales can range from 3.5 to 5.5 m (11 to 18 ft), while the females measure 3 to 4.1 m (9.8 to 13.5 ft).

Its behavior is also more energetic.
