I am looking for a large female for my George and through looking have came across many pictures of both male and female but alot of 4ft male Tegus look like they have very little jowels and look very young? would this be an age thing rather than size? What i'm trying to say is that the pictures I have seen look very similar to the smaller tegs i've had in the past where as any pic of George shows that he's a lump without having anything in the pic to compare him with, if you know what I mean.
