Tell me about tortoises. I don't think I want one but I always see them at shows and when I go to Regal Reptiles and they make me curious because I know nothing about them. I once met one of my friend's pet box turtle and that is about the extent of my knowledge. What do they eat? What are the smaller species? How old to the aforementioned species get? What sort of environmental parameters do they require? Are they social?
