Embryology of dolphins : staging and ageing of embryos and fetuses of some Cetaceans /
Comparative embryology has been neglected in the past decades. In our opinion the decreased interest has been caused by the fact that the time factor has not suffficiently been respected. Therefore we used the Stageing and Ageing Method (Sterba 1995) to determine the ontogenetic age of embryos and t...
