I have a 10 yr old greek tortoise. I was wondering something about the under side of his shell. Near the back part/half of the shell there is a "crease" going from side to side, should the part of the shell below this (tail end of the tortoise) move up and down when you push on it? I never noticed this before about him and am just wondering if that line should work somewhat like a hinge. (as you can tell i am new to turtles and tortoises) Thanks.
