This morning the internal organs were individually explored. The blood vessels near the heart showed that this whale successfully changed from an intra uterine to extra uterine life (technically, the ductus arteriosus was closed).
The ductus arteriosus is a blood vessel that circulates oxygenated blood received from the mother whale while the baby whale is in the uterus. When the baby whale is born, the lungs take over this function and the ductus arteriosus gradually closes and becomes a part of the ligature.
