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.
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 ). It was named in 1758 by Linnaeus , who at the time considered all of the right whales (and the bowhead) as a single species.
The males do not compete as aggressively against each other as male humpbacks. The female may not become pregnant but she is still able to assess the condition of potential mates. [ 18 ] The mean age of first parturition in North Atlantic right whales is estimated at between 7.5 [ 47 ] and 9 [ 48 ] years.
