Phylogenetics of Baleen Whales
At present, there are 15 species of baleen whales that belong to the monophyletic suborder Mysticeti. The family-level designations of Balaenidae (right and bowhead whales) and Neobalaenidae (pygmy right whales) are strongly supported and well resolved. However, family-level designations and inter-r...
