Sorry about the pic. A know a photo from the side would have helped in identification. That skink was so fast and incessantly active. That was the best I could do without catching it. (Which I thought might be counterproductive.)
That cannot be helped. I take the view that we cannot be absolutely certain about each ID but nevertheless it is a valuable record. If someone is later reviewing a record he or she needs to be aware of any doubts that may exist.
