cephalorhynchus การใช้

According to, Peale's dolphin and the " Cephalorhynchus " species are the only dolphins that do not whistle.
Peale's dolphin also shares with several " Cephalorhynchus " species the possession of a distinct white " armpit " marking behind the pectoral fin.
Though both are traditionally placed in the genus " Lagenorhynchus ", molecular analyses indicate they are closer to dolphins of the genus " Cephalorhynchus ".
Mitochondrial DNA studies have indicated that certain dolphin species within " Lagenorhynchus " are actually more closely related to dolphins within the genus " Cephalorhynchus ".
Actually recovered the Peale's dolphins as nested phylogenetically among the species of " Cephalorhynchus ", and they suggest these two species be transferred to that genus.
