I had a rat problem, now have a shell problem

[SteveW]

Well hello TFO, long time no talk. Hopefully you're collectively doing well. I'm back and needy as ever. As stated in the title, one problem dealt with, another remains. Here's the damage:



Another view.



Sid (M.e.e) normally lives in a swamp, and I couldn't get a focused picture without drying it off. Hence the weirdly dry shell. Anyway, anybody have any ideas? I have photos on a currently out-of-commission hard drive so can't compare, but off hand I'd say the split is getting longer.

I have no clue. I haven’t seen this before.
Sorry I have no ideas to offer.[emoji53]

No problem, thanks for chiming in. I was beginning to fear I was posting incorrectly.

It's some sort of a scrape - either from a tooth, or maybe he was trying to go under something that scratched the shell???

I'd like to see some pics of the whole animal.
