What’s this thing circled?

Found this snapper on a trail today. When looking at this picture I noticed this thing that looks like it’s connecting the shell and foot together. But it might also just be a leaf or something that I picked up with it. Any clue as to what this is?

I can’t tell if it’s a stretched out leech or just a piece of lake grass. Either way, it’s not harmful.

unrelated- I'd be terrified of losing my pinky finger holding a snapper like that (yes I'm aware that shouldn't be within bite zone, but im extra cautious with bitey things)

Looks like a long hook
