侏儒露脊鲸（Caperea marginata）是现存的最神秘的鲸类。人们对它的生态和行为知之甚少，但不同寻常的视觉色素[1]、线粒体trna[2]和颅后解剖[3]表明，它的生活方式与其他现存的鲸鱼不同。从地理上讲，卡普里岛代表了唯一完全局限于南大洋的主要须鲸谱系。类似卡佩亚的化石，其中最古老的可以追溯到晚中新世，非常罕见，同样也仅限于南半球，尽管在赤道以北有更丰富的化石采样历史。现在，两个新的更新世化石提供了意想不到的证据，证明在地质历史上有一个相对较短的时期，当时猿猿出现在北半球（图1A，B）。
The pygmy right whale,Caperea marginata, is the most enigmatic living whale. Little is known about its ecology and behaviour, but unusual specialisations of visual pigments [1], mitochondrial tRNAs [2], and postcranial anatomy [3] suggest a lifestyle different from that of other extant whales. Geographically,Caperearepresents the only major baleen whale lineage entirely restricted to the Southern Ocean.Caperea-like fossils, the oldest of which date to the Late Miocene, are exceedingly rare and likewise limited to the Southern Hemisphere [4], despite a more substantial history of fossil sampling north of the equator. Two new Pleistocene fossils now provide unexpected evidence of a brief and relatively recent period in geological history whenCapereaoccurred in the Northern Hemisphere (Figure 1A,B).
