Recently I noticed the bottom plate of my turtle's shell has been growing in an odd way. She isn't acting sick, or anything like that, so I'm not really panicking yet. I just don't understand what's happening. Is this normal? I've attached a photo of the shell. The 'gap' between the plates is actually hard and doesn't appear to be sensitive. There aren't any soft spots on the shell and her skin and top shell appear normal.
