Notes on the Anatomy of the Heart in the Harp Seal ( Pagophilus groenlandicus Erxleben, 1777)
The heart of the Harp seal ( Pagophilus groenlandicus) is described based on the dissection of six specimens of both sexes ranging in body weight from 23.2 to 46.4 kg. The heart is characterized, as in other seals, by a transverse broadness and a flatness of the ventricles along with an apex formed...
