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).
Balaenidae consists of two genera: Eubalaena (right whales) and Balaena (the bowhead whale, B. mysticetus). Balaenidae was thought to have consisted of only one genus until studies done through the early 2000s reported that bowhead whales and right whales are morphologically (different skull shape) and phylogenically different.
Balaenoptera (from Latin balaena 'whale' and Ancient Greek πτερά (pterá) 'fin') is a genus of rorquals containing eight extant species. [2] Balaenoptera comprises all but two of the extant species in its family (the humpback whale and gray whale); the genus is currently polyphyletic, with the two aforementioned species being phylogenetically nested within it.
The blue whale (Balaenoptera musculus) is a marine mammal and a baleen whale.Reaching a maximum confirmed length of 29.9 m (98 ft) and weighing up to 199 t (196 long tons; 219 short tons), it is the largest animal known ever to have existed.
Through the 19th and 20th centuries, in fact, the family Balaenidae has been the subject of great taxonometric 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.
Balaena is a genus of cetacean (whale) in the family Balaenidae. Balaena is considered a monotypic genus, as it has only a single extant species, the bowhead whale (B. mysticetus).
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 ...
