Hi, I was just sent an email needing an I.D. on a tortoise. My first thought is Texas Tortoise, but I need an expert I.D. Desert tortoise look too similar to me. This is the only picture I was sent. Thanks!
If I'm reading this correctly, the desert tortoise has a nuchal scute (as does the tortoise in your picture), but the Texas tortoise does not. I'm going with desert tortoise (Gopherus agazzii)
Every image I've seen of a Texas Tortoise has a nuchal scute. The one in the link you send almost looks deformed. It may have not been a good specimen for that photograph. Hmmm.........
