Anyway we placed the turtle in some more permanent shade and promised to come back the following morning to administer medicine and check it's progress.
Unfortunately when we returned the turtle had died during the night. Very sad for the turtle and tourists involved. However, this gave us the opportunity to perform an autopsy. The aim was to primarily determine the cause of death and then check for other bits of interest (i.e plastic in the stomach, other signs of illness). We performed the autopsy right on the beach under the somewhat horrified eyes of tourist however some were fascinated and Rosana quickly too the opportunity to teach onlookers on the biology of a turtle.
First task was the cut through the thick plastron on the underside of the turtle. Luckily a line round the edge can be used as a guide and after 5 minutes the whole plastron section was removed. This revealed a mass of muscle tissue attached each fin. There was a surprising amount of muscle especially on the front two flippers. Rossana cut the muclse out and threw it in a purposely dug hole along with the plastron. Under the muscle was a thin layer of membrane which seperates the muscle from the organs. Down the hole with the membrane unveiling a neatly arranged section of organs.
One by one they were removed and any relavant infortion recorded. The colours of some of the organs were very vivid greens or purples. The eusophgus was very interesting, turned inside out a tube of long spikes could be observed. Apparently turtles don't chew their food like a human would so it passed to the digestive system by rows of spikes with push the food down.
The blood inside the turtle was heavily coagulated and their was also so visible brushing on the plastron leaded us to believe that yet another turtle had falling foul of a boat in the harbour. After swimming with its injury the turtle gave up and retired to the beach where it then died. The turtle was a juville female, sad to see it go but a great opportunity to learn some hands on biology.
