セミクジラ
In 2001, Brownell et al. reevaluated the conservation status of the North Pacific right whale as a distinct species, and in 2002, the Scientific Committee of the International Whaling Commission (IWC) accepted Rosenbaum's findings, and recommended that the "Eubalaena" nomenclature be retained for this genus. A 2007 study by Churchill provided further evidence to conclude that the three different living right whale species constitute a distinct phylogenetic lineage from the bowhead, and properly belong to a separate genus.
