Hello, am new to owning tortoises but have owned many reptiles. I am unsure if this tortoise is a russian, greek, etc. as i bought it from petsmart and they had no clue as to how old they are, what gender they are or what type they are. Please help to identify age, gender and type. He/she looks a bit more worn than photos of tortoises on the internet, but I don't know if that's because he is old or because he is unhealthy. Thanks!
