I too have an aldabra from the same source. Mine had the same writing on the shell. I suspect the "CE" stands for Chris Etsep maybe they mark the ones that are going to him ahead of time. Another interesting tidbit of info is that the shell shape of Unle Bri is similar to my aldabra- lacking the high dome seen in those which come from Aldabraman. It would be really neat to find someone willing to do the genetic tests and see what mix of genetics and what specific islands all of these little guys ancestors came from. This is all so fascinating to me.
