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).
Ambergris (/ ˈ æ m b ər ɡ r iː s / or / ˈ æ m b ər ɡ r ɪ s /; Latin: ambra grisea; Old French: ambre gris), ambergrease, or grey amber is a solid, waxy, flammable substance of a dull grey or blackish colour produced in the digestive system of sperm whales. [1]
The point where a node branches off is analogous to an evolutionary branching – the diagram can be read left-to-right, much like a timeline. The following cladogram of the family Balaenidae serves to illustrate the current scientific consensus as to the relationships between the southern right whale and the other members of its family.
The right whales were first classified in the genus Balaena in 1758 by Carl Linnaeus, who at the time considered all of the right whales (including the bowhead) as a single species. Through the 19th and 20th centuries, in fact, the family Balaenidae has been the subject of great taxonometric debate.

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.
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.
