Ah, I thought with the ? marks after wards you were asking if male. How large is it

Judging by the size of claspers it is close to being mature. With that being said,
if it was full marble it would have some type of marbling, even if it is a low grade
marble. At least some hints or shadows of Marbling between the spots.
