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).
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).
These are narrow and approximately 2–2.8 m (6.6–9.2 ft) long, and are covered in very thin hairs. [27] Right whales have a distinctive wide V-shaped blow, caused by the widely spaced blowholes on the top of the head. The blow rises 5 m (16 ft) above the surface. [28]
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]
It does not migrate but remains within this area year-round. Little is known about the feeding behavior of Rice's whales, but data from a tagged individual revealed a diel vertical diving pattern , in which the whale spends most of the day feeding at or near the seafloor at depths of up to 271 meters (889 ft) and night at the surface.
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 ...
The Antarctic minke whale or southern minke whale (Balaenoptera bonaerensis) is a species of minke whale within the suborder of baleen whales.It is the second smallest rorqual after the common minke whale and the third smallest baleen whale.
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.
