Balaena

Balaena montalionis

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 first described in 1758 by Linnaeus, who at the time considered all of the right whales (and the bowhead) as a single species. Historically, both the family Balaenidae and genus Balaena were known by the common name, "right whales", however Balaena are now known as bowhead whales.
