It all depends on the location. If it is from Limpopo province, it is definitely not
A.etoshae, but as I said, it doesn't look like the normal
A.aculeata either. The differences can sometimes be quite small (
A.hispida vs
A.aculeata), and because their colouration varies greatly, it may only be something like the relative lenght of the tail, ridges down the back, shape and extent of keeled dorsals scales, etc. With an accurate location we should be able to narrow it down a lot! I amost forgot about
A.armata, but can't remember the difference between
A.aculeata and
A.armata I think it had something to do with ridges or spike arrangements, but will have to check later (or wait for one of the pros to reply).
We must remember that a photograph can hold just as much as we put into it, and no one has ever approached the full possibilities of the medium - Ansel Adams
