I'm absolutely rubbish at this so don't take my word for it.... but I'm going to guess at an aldabra but wait for a few more opinions I'm probably totally wrong.
That looks like a big brother to one of my California desert torts, or, as Tom said, the Latin species name gopherus agassizii. Are you here in Cali, as your name suggests?
Thank you all for your replies, even you, LeopardTortLover.
I am from Southern California, hence the name. It is not a CDT. This tort has a sharp beak unlike the CDT's soft mouth. I was thinking more on the lines of a Marginated or Greek but I wanted others thoughts. I have added a couple more pictures to clarify. Her shell is 7" in length.
Thanks again.
It does appear to be a Greek tortoise, Testudo graeca ssp. but I do not believe that it is an Ibera Greek (T. g. ibera). It lacks several characteristics of that subspecies. The clarity of the of the color, patterns and what would be normal growth and shape are obscured by the prominent captive growth. Lots of ridges and non-typical flaring growth.
It looks more like it could be a Caspian Greek, T. g. buxtoni or possibly T. g. perses which I believe "at the moment" are considered to be one in the same subspecies.
Regardless of subspecies, it does appear to be a Middle Eastern Greek subspecies.
I sent the pics to one of my tortoise friends who has T.g. buxtoni, and he confirmed that this is most likely one of them. He said that something looks funny about the plastron, and agreed with the accelerated growth that several others have mentioned.
I actually fostered a T.g. buxtoni earlier this year for International Reptile Rescue - I'm attaching a few pics (before I trimmed his beak). He has now joined Tim/Robin's group.
Tell us more about your tortoise if you know. Who, what, where ...
I seem to remember reading about this type being bred by a family in northern California in the 80's and the babies sold to pet stores.
