Mine was an Alligator Snapping turtle, Ive been hooked on them ever since I got this book as a kid about reptiles, and it had a real big fold-out page with a huge picture of a hunting Alligator snapper.
It's been my favorite turtle ever since. :)
I say don't buy tortoises from petstores (or turtles) because they simply don't care, they just see animals as money.
At my local PetCo, they sell Red-Eared Sliders. I've seen the conditions they keep them in. They keep around fifteen turtles, each badly pyramided in their own special way...
Same here, looks almost like that side of his head didn't develop as well. I don't know much about tortoises, though, so I kept my trap shut.
Now if the knowledgeable fellas say it, though...I agree. :)
The tail looks female to me, because of how small it is compared to the rest of the tort.
The plastron looks as if it's pushed out a little, like in females, because they don't need to mount.
Hope it helps!
