External Morphological Characterization of 60-Days Gestation Myocastor coypus (Coypu) Fetuses

The main objective of this work was to carry out the external morphology characterization of 60-days gestation Myocastor coypus (coypu) fetuses since this stage could be considered a crucial point in the prenatal development in this species. Fourteen fetuses out of three litter were analised. Gestat...
