Balaenidae (/ b ə ˈ l ɛ n ɪ d eɪ,-d iː /) is a family of whales of the parvorder Mysticeti (baleen whales) that contains mostly fossil taxa and two living genera: the right whale (genus Eubalaena), and the closely related bowhead whale (genus Balaena).
Throughout history, the family Balaenidae has been the subject of great taxonomic debate. Authorities have repeatedly recategorized the three populations of right whale plus the bowhead whale, as one, two, three or four species, either in a single genus or in two separate genera.
The fin whale is the fastest among baleen whales, having been recorded travelling as fast as 10 m/s (36 km/h; 22 mph), and sustaining a speed of 2.5 m/s (9.0 km/h; 5.6 mph) for an extended period. [51] While feeding, the rorqual jaw expands to a volume that can be bigger than the whale itself; [52] to do this, the
†Balaenula astensis Trevisan, 1942 (from Italy) [2] Balaenula is an extinct genus of baleen whale species which lived during the Pliocene epoch of Europe and possibly North America. [ 3 ] [ 4 ] Balaenula is a small whale measuring within the range of 6–8 metres (20–26 ft) in length.
The communities first split because of the joining of North and South America. The rising temperatures of the equator then created a second split, into northern and southern groups, preventing them from interbreeding. [20] "This puts an end to the long debate about whether there are three Eubalaena species of right whale. They really are ...
The southern right whale (Eubalaena australis) is a baleen whale, one of three species classified as right whales belonging to the genus Eubalaena.Southern right whales inhabit oceans south of the Equator, between the latitudes of 20° and 60° south. [5]
